    Part 20.

    I turned my attention to deck planking and did some experiments with regard to the caulking.
    I have not planked a deck before though I have read plenty of great articles on this site and in books.

    In Ted Frosts book From Tree to Sea when it comes to deck caulking he says that the caulking was not scraped after being applied, just left in an uneven way to be worn off by the crew as they walked on it, he also says that the deck wasnโ€™t planed only the high spots removed, making a comment that โ€œit is a working boat not a pleasure yachtโ€.

    With this information I though that a slightly in-perfect deck would be more realistic.

    In my first experiments I used black paper of varying weights this worked well though a little to consistent for what I was looking for.

    These experiments were done whilst Melbourne was in one of itโ€™s hard Covid 19 lock downs during 2020, therefore I used what was to hand.

    I am not saying that this is an original idea though I donโ€™t recall hearing of it being done like this before so after some thought I tried mixing artists oil paint with Titebond 3 glue, this took far too long to dry.

    I then tried artists acrylic Gouache a thick acrylic and Tamiya acrylic mixed with Titebond 3 (separately that is), this worked alright but was too runny so I tried adding a filler, in this case West Systems 406 because I had some in stock, I also tried Micro Balloons however they didnโ€™t mix in all that well, the West Systems 406 mixed in nicely.

    Doing some more experiments, I found that adding a spacer between the planks was even better, an unexpected bonus is that once dry the joint has some flexibility.

    I settled on a mixture of Titebond 3 with Matisse, Mars Black, flow, artists acrylic and West Systems 406.

    The best thing is that I have a lot of control over how neat or messy the caulking is, my hope is to leave areas where I am guessing that the crew wouldnโ€™t normally walk in a messy condition, thatโ€™s the plan time will tell how it works outโ€ฆ.

    I have also played around with weathering the deck, still more to be done on that.
    I did find out that you cannot leave steel wool in vinegar for to long as it goes a rusty colour.

    Before I can start planking the deck I need to make up the planks, I have a couple of blocks of Huon Pine that are awaiting being turned into sawdust and planks.

    The next thing I looked at were what Ted Frost calls Binn Irons or Bend Irons there are 3 of these on each side of the hull, mounted one on each of the top 3 strakes. Giving some protection to the hull.

    I couldnโ€™t find a commercial Brass 1/8โ€ โ€œDโ€ section so I thought I would try making some, this would need to be machined from 1/8โ€ diameter Brass rod.

    I know from previous experience that machining long thin material in a conventional setup, for example holding in a vice or clamping at either end is not possible made worse by the material I wanted to hold being round and of small diameter.

    I pondered on this problem for a while and came up with an idea of making a jig to feed the material through with a milling cutter around midway to remove half of the material therefore round bar in one end and โ€œDโ€ section out the other.

    This jig is basically a piece of mild steel with a hole drilled right through, the diameter of the material with a slight amount of clearance to allow the material to slide through easily, then around the middle milling a pocket to the desired depth for the milling cutter to do itโ€™s work, then on the output side I drilled and tapped a hole for a screw adjusted to stabilise the โ€œDโ€ section as it comes through.

    I tentatively started machining and was surprised how quickly I was able to manufacture all the โ€œDโ€ section material I required.
    SAFETY WARNING: This sort of setup is not without itโ€™s risks there is potential risk of personal injury or damage to the cutter.

    This post brings my build up to date, the glacial speed that I progress at will be more evident from now on.

    I am currently working on a router table now that my long awaited Incra jig has arrived this is taking up my hobby time at present.

    Thanks for looking in, for all the likes and all those that are following, I do really appreciate them and hopefully you will remain following once the pace of posts slows dramatically.

    Cheers,
    Stephen.

    Hi Martin,
    Thanks for asking.
    I am sorry to say that I haven't done any work on the Drifter for a variety of reasons, I hope to get back to it in the near future, mind you I have been saying that most of this year.

    Cheers,
    Stephen.

    A short working time is a problem.

    Thankfully the mix I made up has a good working time.

    Hi Stephen.
    Like you I tried various ways of simulating 'caulking' with various mixes of adhesives with colourants, I experimented with a two part wood filler with a black colouring powder normally used to colour mortar for ornamental brickwork that worked particularly well but the working time was far too short to be practical. In the end I settled on thin black plasticard (styrene) strips which gave a very neat appearance when sanded back and lacquered which was my aim, but your requirement of a 'messy' finish, while unusual, could look very effective ๐Ÿ˜€

    Hi Graham,

    Do you have a small saw bench?
    If you do you can put a slitting blade in instead of the normal saw blade and use that to slit your tube, keeping fingers well away of course.

    Stephen.

    Hi Stephen,

    The C section will be very small. Iโ€™m considering using 1/16โ€ brass tube, 0.014โ€ wall thickness. I donโ€™t have a mill, and the tube is going to be fragile, so I plan to make a jig similar to yours to old the tube, and then to file away half the tube rather than mill it.

    Might not work, but it will be interesting to try. Makes the modelling more interesting if nothing else ๐Ÿ˜Š

    Just a quick one, If you are looking for Half Round Brass there is a supplier in the UK called EKP Supplies. Does loads of stuff inc stainless bolts in BA etc. I couldn't remember his name this morning. But dug his name out of my workshop files

    I like the D section jig. I have a need for some small C section brass which I might try producing using your jig design to halve s length of brass tube

    There are a number of good model engineering suppliers still in Aus, from memory I didn't think to look at what they had.
    You can buy "D" section but it was far too big.

    Hi Steve,
    As an Ex Model Engineer that's the way it should be done but, as you say not without it's hazards! The minimum size I have done this to is 1/8". there used to be some good ME suppliers in Aus. don't know whether they still exist sometimes they would have D Section.
    Brass can be tricky as the cutter can pick up so well done. Soft and slow

    Part 19.
    With things settling down in the engine room, and having run my plant several times without any real drama I started looking at what next.

    Early in this project I decided that a forced ventilation system would be something I would try, seeing I donโ€™t like the idea of letting convection move the hot air out of a fairly enclosed area.

    To make this happen I wanted to fit a fan at either end of the boat with one in the bows pushing outside air in and the other pulling air out, or maybe pushing air in creating a combined flow up the funnel, ventilators and any other opening.

    Luckily there is a hooded companionway in the bows under neath which I can hide a fan.

    With the rail back in the hull, I worked out the fanโ€™s location on the deck then made a card board representation of the companionway opening.

    All of this work was made a lot easier due to there only being deck beams, therefore I could clearly see where things could go.

    A cardboard mock up was made of the duct that would connect the fan to the deck beams.

    Then once the shape was settled these shapes were transferred to ply wood cut out and glued together. The whole assembly including fan is easily removable.

    I then made a stand to sit the rail on when out of the model, while designing this I decided to make it multi purpose, one other use being to keep the lower hull and upper hull separated for unplugging a multi pin plug another use being to display the model.

    In the removable deck section there is a bit of wiring that in my opinion needed to be done now while there is easy vision and access. Wiring is needed for lighting, power to a voltage multiplier to run the 2 fans at up to 24 volts, for 2 servos to control the mizzen sail one servo hopefully to raise and lower the other for sail trimming.

    All of this going through a multi pin plug, the plug I bought is only an audio plug but seeing that I think there will only be about 1 amp running through any one of the pins at any one time I think it should do the job.

    With the rail in there is not a lot of room for much else, funny how it has filled up with equipment considering I thought there was plenty of room in the beginning.

    If you have any questions donโ€™t hesitate to ask.

    Thanks for looking in.

    Cheers,
    Stephen.

    Part 18.

    Testing of steam plant!!

    I started testing and rectifyingย problems and it still continues, both my feed pumps decided they didn't want to work after sitting for quite a while, I discovered that both of the inlet check valvesย (3mmย  balls) were sticking / jammingย in their housings so I changed them to 1/8" balls problem fixed.

    Unfortunatelyย it does my head in when I run into problems, in my head it should just work!!!
    This is something that is improving as I get older, I am now less likely to throw my hands in the air so to speak.

    Then on testing for gas leaks using compressed air I found that the gas regulator I bought didn't have the output fitting soldered on properly and was leaking quite a bit, I have now soft soldered the leak.

    Then the output from my gas shutoff valve would not seal and after many headaches later I made a new output fitting machined off most of the old on then soft soldered the new one on problem fixed, looks like the guy in quality inspection was asleep on the job.

    As testing progressed the gas metering and shutoff valve's work a treat. I didn't find out there was a problem with the gas shutoff output until I lit the burner and after a minuteย I had flames where I didn't want flames. This was quite alarming though all was under control after flicking the switch on the transmitter that closes the shut off valve.

    A few days later things didn't improve much when I tried to run the steam plantย  (I went out with the expectation everythingย would work, thisย being theย main problem) and nothing seemed to work apart from feed pumps and gas valves that is.
    I tried lighting the new burner that was now in itโ€™s correct place for the first time and it would not run when inside the generator ( I have probably made the flue diameter too small, I did think of a temporary fan to induce a draft through the generator, though I didnโ€™t try it ) when I got it to run by removing the bush that centralisesย it in the generator it didn't seem to do much. Not happy!!!

    I went inside for a while to settle down and start to think about what had happened.

    I thought I would try the old Cheddar steam burner ( I had made up pipe work to try it anyway) what a difference things started to happen, I discovered that I had filled the entireย system with water including the engine which I think sort of hydraulicโ€™ed and locked up I had hot water coming out all over the place and not much else happening.

    I was ready to give the whole thing up and either buy a commercial steam engine or just put an electric motor in and be done with it. To say I felt dejected would be an understatement.
    I went back inside again. I even had a look at a beautiful Martin Baylis Engineering twin slide valve engine,ย I hate to think how much one ofย those isโ€ฆ.

    Once I started to rationalise the whole thing I started to calm down, I decided that next morning I would run the engine on compressed air firstย  to prove that it would run.

    So next morning I hooked compressed air up to my engine and it ran, I found that the main leaks were from the forward/reverse valve, I removed it then pulled it apart flattened both faces reassembled and ran with compressed air, the engine seemed to run well.

    I changed the feed pump curve on the transmitterย and halving the feed pump max speed to reduce water flow.

    I tried running the plant again and to my joy it ran, still pumping too much water though. It has run several times now still reducing the amount of feed water.

    There is still more to do on the plant, like adding temperature sensors to monitor steam temperature and maybe ambient inside temperature.

    I did a couple of short videos of the plant starting and running, copy these links into your browser and hopefully they will work!!!

    Hi,

    I know that steam locos have a bypass valve on the water feed pipework to allow the partial return of the feedwater. Would one help with your system?

    I'm enjoying your blog!

    It is great to see you have the engine moving.
    Looking at that setup on the bench it looks like some mad science experiment.

    Part 17.2.

    Any non coloured Brass parts were given a coat of clear Lacquer.
    Control of the steam engine requires 3 servos, one for gas metering, one for feed pump speed, one for forward / reverse on the engine.

    All controlled from a single input on the transmitter, which is a Taranis 9XD+ programmed via OpenTX Companion.

    A switch on the transmitter controls a fourth servo for the gas on / off valve.
    ย 
    All gas equipment is painted white.

    If you have any questions donโ€™t hesitate to ask.

    Thanks for having a look.

    Hi Ianh,

    Unfortunately they would be warmed up because of the heat transferring system,(the copper tube wrapped around the gas cyl and separator) pumping water around the separator picking up heat then moving it to the gas cylinder cooling the water and returning around.

    Part 17.

    Back to the engineering side of things, next job was gas control.

    I had a look around the internet trying to get some design ideas for RC servo controlled gas metering valves to no avail, all I came up with were some commercially made RC servo controlled gas shut off valves.

    For one reason or another nothing suited my instillation, in the end I decided to make 2 externally similar valves and mount them on a manifold, similarly to how Hydraulic and Pneumatic valves are mounted in industrial installations.

    One reason for this was to reduce overall space taken.

    There are some things that I need to draw before attempting to make and these valves fall into this category. Using CAD I designed then built a metering / flow control valve and a shut off valve.
    The metering valve allows me to go from an idle flame through to full flame.

    I am also using a small commercialย gas regulator this should give me a constant pressure and therefore a constant flame.
    ย 
    I started buy making the metering needle this was quite tricky, being made from Stainless Steel with a taper of around 2 degrees, this made for a taper length of around 15mm going from a point up to 1mm diameter add a polished finish and this took me around one day to do.

    In the end I rejected the first needle and proceeded making up the body linkage and servo horn adaptor.

    For the servo horn adaptor I machined a disk with a groove on the lathe, then in the mill I machined a notch finishing off with a file.

    The small radius was filed by hand up to a guide turned on the lathe, this made it really easy to achieve a nice radius.

    Two pipeโ€™s were made one for each gas burner that I have, when I am making up odd shaped piping I use wire of some sort that is close to the same diameter as my pipe in this case I used heavy gauge soft solder bent to shape as a guide.


    I also made up a servo mount for the forward/reverse and rudder servos along with 3 special long screws for holding down the plant rail, these screws enable installation and removal without tools also it is easier.

    Continuing in part 17.2.

    Hi mturpin,

    I tend to have a bit of a love hate relationship with the engineering side of this build, it is all good until testing starts. haha.

    I believe that well made components will preform better for longer than roughly made items.

    At the end of the day it is your build and you are allowed to over engineer things if it suits you as long as you are happy with the extra weight.

    Cheers,
    Stephen.

    Hi Steve I do like the engineering side of things. There is some really precision work there a credit to you. I sometimes think that the engineering part of boat building is the most interesting, however it usually causes issues with weight as I tend over engineer a solution as others have commented, but I like engineering.
    Great job Steve

    Part 16.

    The rudder was something I was looking forward to building for a long time.

    Combining a small amount of woodwork with a reasonable amount of metal fabrication, having done a lot of work on the steam plant I chose to take a break from that aspect and make the rudder.

    My aim was to build a rudder and rudder post as close as possible to the original using the plan and book From Tree to Sea as a guide, while being able to remove it completely from the boat.

    My initial design envisaged a few compromises and alterations the most obvious being distance between rudder shaft and rudder post.

    After finding that the rudder shaft tube was not quite on the right angle, I removed it and elongated the hole slightly.

    Then I started making up a lower rudder shaft support or โ€œTOE IRONโ€ as this fixes the rudder shafts lower position.
    This was fabricated from brass, silver soldered together.

    Next was the โ€œTโ€ section rudder post, I tried to find a length of commercially made brass material with no success.

    There were two ways I could go, fabricate or machine from solid, I wasnโ€™t confidant of fabricating a โ€œTโ€ to the quality I was looking for so I machined one from solid brass in the mill.

    Next, I made the upper and lower rudder post brackets.

    Cutting them from brass sheet then folded them to shape. These were silver soldered to the rudder post in a jig of sorts to assure alignment.

    Making the hinge like components that bolt to the Rudder post and retain the rudder shaft, proved time consuming.

    The miniature HEX nuts and bolts are homemade, commercial ones having too big a HEX for this application.
    Turned out the woodwork part of this was not much work.

    As my build progressed, I ended up either moving position, remaking or modifying some of the components moving away from my original design and finding that I was able to build a more accurate representation whilst still being completely removable, all taking considerably longer than expected, nothing new there.

    Thanks for having a look.

    Cheers,
    Stephen.

    Part 15.

    With most equipment mounted on the rail I pulled it apart and painted it.
    Turns out there are quite a few parts!!

    I painted the rail parts dark Brunswick green, feed pumps and manifold Blue.
    Stop valve and pressure relief valve Red. Parts that are natural brass or copper were clear coated.

    Somewhere along the way I dropped the idea of using an Arduino Nano and settled on using a FrSky Taranis 9x plus, programmable radio.
    This radio has Telemetry along with the benefit of being able to be programmed using Open TX Companion.
    This is an open source program that runs on a computer allowing me to create a program on my computer test it on the computer then download to the transmitter.

    I have not tried to copy what Ian Gerrard did in his truly amazing control system however I have taken the concept and adapted it to a manageable level for me.

    After the paint had fully dried I reassembled the rail.
    I had read that balsa wood has really good insulating properties so I made an insulating tub for my steam manifold from it then painted it silver.

    Before I mounted too many things to the rail I set the relief valve using compressed air.

    I mounted all the equipment that has been made so far to the rail.

    Thank you to those following and for all the likes, I really apprentice them.

    Cheers,
    Stephen.

    Hi Stephen,
    There is a massive amount of work that you have put into the motor, boiler and valves and other bits and bobs.
    She is going to look fantastic when she is finished.

    Part 14.

    I decided to build two feed pumps from a Peter Arnot design featured in Model Boats magazine mounting them horizontally this was in an effort to smooth out the feeding of water, my theory being that If you feed a pulse of water into the system it can pulse at the other end.

    Funnily I have only just recentlyย found an article in an old Model Engineer that said a 3 cylinder pump was preferable for feeding flash steam systems.
    My pumps are driven by a small motor through a speed control. The more steam I want the more water I feed.ย 

    I decided to make a rail to mount as much equipment as possible onto.
    Using 2 lengths of ยฝโ€ SHS (square hollow section) with separating pieces screwed on.
    Mounts were made and epoxied onto the keel, using a temporary setup to hold the rail perpendicular to the centre line.
    The rail is held down by 3 screws for quick removal.

    After the rail was made but not painted yet I positioned all the equipment.
    Because the flue/exhaust for my Steam generator is not positioned directly under the funnel I made up an offset flue out of steel pipe.

    I made my own stop valve, pressure relief valve, manifold and separator.
    Modified model aircraft fuel tanks are used for feed water and recirculating water tanks, a small pond pump is used for circulating water.

    I was starting to get worried whether my drifter had put on too much weight.
    So I wrapped the lower hull in plastic film and did a practical test in a wading pool, this showed no problems to my delight.
    Requiring some ballast and sitting at the preferred waterline, with no need to go on a diet.

    Thanks for having a look.

    Cheers,
    Stephen.

    Thanks Martin,

    Flash steam is more complex than your run of the mill boiler.

    You could be right about the mad bit, haha.

    Thanks again.

    Hi Stephen,
    There is a lot more to steam power than meets the eye.

    The last three photos look like something a Mad Professor is experimenting with and not a water to steam converter LOL!!

    I dose look extremely impressive though
    Excellent workmanship.

    Part 13.

    One of the guys at the model boat group I belong to tried a Flash steam / steam generator / mono tube boiler or which ever name you wish to use.

    Tom was saying that he should be able to raise steam within a couple of minutes with his new system, this got my attention!

    I donโ€™t like the amount of time my boiler takes to raise steam, so I thought I would look into this different way of producing steam for those who may not know a steam generator otherwise known as flash steam or monotube boiler, all the same thing.
    You pump water in one end of a tube, heat it and steam comes out the other end, as there is no storage of steam unlike a conventional boiler, when you take the heat off the steam stops, more importantly for me it raises steam quickly.

    There is not a lot of information about flash steam. Most information I found was related to steam cars or tethered hydroplanes. Although there are a couple of sites that are of use.

    Then once again it is a good thing to read a magazine like Model Boats because in the January 2016 Model Boats mag there was an article about an Edwardian Steam Launch, for those who are interested here is a link to the article;

    http://www.modelboats.co.uk/news/article/model-engineer-exhi...

    I tried to find out more about this model, eventually I found that Ian Gerrard wrote an article for Engineering in miniature magazine.

    By now I was totally sold on the idea of a steam generator.

    Below is a link for the article in PDF that goes into how he used computer control to control his monotube boiler!!
    Wow I was and still am blown away by his approach to controlling his steam generator.

    I am not even close to having the ability to do such a thing although initially I thought I would probably use an Arduino Nano as the micro processor if I went down that path.
    Again for those interested in how he made it happen, copy the link below.
    http://eddy.dawa.de/DUK-flashboiler/elektronisch_gesteuerter...

    This is a you tube video of the latest boat this guy has made.
    https://www.youtube.com/watch?v=Az_U-Qeb3fY

    From the research I did it appeared that heavy wall 3/16โ€ copper tube was preferable the other important requirement is for the tube to be as long as possible.

    I had a couple of ideas for how to improve the insulation of my future steam generator and whilst discussing this at a model boat group meeting Alan came up with the brilliant idea of using a vacuum to insulate the inner from outer.

    I found an old stainless steel vacuum flask that looked like the right size, checked it in the hull to make sure.
    Holes were cut into the vacuum flask where required then bushes silver soldered in. This really tested my silver soldering ability.

    I will let the photos speak for themselves.

    Thanks for looking in.
    Cheers,
    Stephen.

    Hi Martin555,
    Thanks though I don't completely agree that what I am doing is quote "way above my skills" they are simply a different set of skills, you are a very skilled model maker in my opinion.

    Part 12.

    I decided to leave planking the deck and making the bulwarks until later, my main reason is ease of positioning equipment when I have clear sight through the deck beams, this turned out to be a really good idea.

    Back to the steam engine. The following steam engine issues happened over a number of years, not necessarily in order with building of the hull as presented in these articles.

    To recap from part 2; first run showed that it took a very very long time to raise steam and once it did raise steam the engine didnโ€™t run for long before the pressure dropped.

    I only ran the engine three times before I had large leaks mainly between the cylinder port and distribution block faces, the leaks being so big the engine wouldnโ€™t run properly!

    I wasnโ€™t sure why I was having these problems, I thought I had made the engine as accurately as I could.
    I pulled the engine apart and found that the distribution block now had slop in the bearing for the cylinder pivot.

    I was puzzled that this should occur with so little running time, at that point I thought either the pivot pin or bearing hole wasnโ€™t square to there respective face.
    I couldnโ€™t understand how this could happen, but I couldnโ€™t think of any other reasons either.
    So I set up the cylinder in a 4 jaw independent chuck, not easy to do, then took a skim off the face, then repeat again for the other cylinder.

    Next I setup the distribution block on a face plate and bored the bearing hole out this would ensure an absolutely perpendicular hole, then made a bronze bush and pushed it in.

    I reassembled the engine with high hopes only to have a similar result after a few runs, I had huge leaks again, I started to think this steam thing might not be for me.

    Then while I was exhibiting my partly built drifter at a model boat show at the Queenscliff Maritime Museum in Queenscliff a bay side township in Victoria, Australia, I met a guy who had built 2 of the same engines that I had.
    While talking he asked me how my engine was going and I told him not so good.
    He told me that one of his engines ran beautifully while the other was terrible like mine.

    He then proceeded to tell me how he over came the problem also saying he would send me some photos of his modification, photos eventually arrived of his floating cylinder retaining device ( I donโ€™t really know what to call it ).

    I proceeded to copy his modification along with another modification on the cylinder faces to under cut between the pivot pin and steam port, reducing surface area.

    Then for the second time I set the distribution block on a face plate and bored the pivot hole out this time for DU Glacier bushes.

    I re-assembled the engine then put it aside, with the hope those problems were fixed.

    Thanks for having a look.

    Cheers,
    Stephen.

    Nice looking engine Stephen,

    Way to complicated for me, but your engineering skill have proved to be excellent and you have made a lovely little engine.

    Well done.
