LATEST SMOKER, E-CIG ELEMENT

Not sure I understand what Vaping is .............The tanks I presume are part of the system - you will have to go into a great deal of detail for ignoramuses like myself to understand whats going on.......... I have visions of one of those very involved Turkish pipe things standing up in a boat shaped like an Alladins Lamp... Seriously I like your idea of creating an easy to use working smoke unit JB - would be of great use to all boat s . Have only one small steam engine set left now - the nicer gunmetal type sold by Midwest ..... all the rest have been sold over the years as its very time consuming firing up - watching the sailing time - and the safety bits too - simpler to use electrics with dummy boiler & engine in open boats - so a smoke unit would be good there too - perhaps camouflaged as the boiler itself. How about that for your next project!

This is my Sir Kay (T241) - Round Table Class Minesweeper. it is from the Caldercraft range and I was fortunate to recently acquire it - I would have much preferred to have built it but couldn't miss the opportunity of it being given to me by an old retiring . it just needed new RC throughout, a good clean, a tidy up and some fresh paint here and there plus a bit of rigging renewal. Not tried it in the water yet but will do tomorrow at our Club meet. (Motor: MFA Geared 2.5:1) (ESC: Mtroniks) (5/10)

Servo Mount

The aluminium servo mount is similar to what I have used, but the quality here is a step above excellent. 👍 I use aluminium angle sections as well, so they can be made into a Z section depending on the application. I use 2mm to 3mm diameter bolts and drill and tap into the sections to secure the servos. This method can be used on any size of servo as they come in various sizes. I have also noticed that some s put two linkages on rudder servos. if both linkages worked in tension only (ie both pulling), then this is necessary, but if the linkage is a rod that works in both tension (pulling) and compression (pushing) then there should be no need for duplication. None of my models have this arrangement.

Hallo Gary, Your curious response to my post prompted me to look back at your history. In your very first post on the site four years ago I ran across this about a tug project of yours - "My reason for trying to build this particular kit in the first place, is it is 39 inches in length with a beam of 10 inches, with a one piece large superstructure making it ideal for a steam engine." All very fine but it underlines the snag many of us have, especially naval s with 10to1 LoA / Beam ratio, that we simply don't have the beam and superstructure height necessary for steam power plants. Regards, Doug.

My Dear Gary, If you wish to start a Steamer thread then why not title it as such? In no way did I wish to be AntiSocial. I simply responded to your somewhat provocative question, which I quoted in my previous post, as did several others on the site in similar vein. Whilst I admire those who can build steam engines, and I have done that on this site, I simply listed in my response to your (perhaps rhetorical question?) the obstacles that most s are faced with when it comes to steam power in models. Perhaps I should have added number 7. - For most of us the SHIP is the main objective and not the power plant which in the vast majority of cases is hidden under deck. If steam is your THING - GREAT I have no problem with that. More power to your boiler 😊 It just won't work in my ships and boats. Esp. my subs 😉 And I don't have the patience for all the faffing about necessary to get going at the lake - one of my six points mentioned above. And I suspect that goes for many other contributors to this site. My post simply consolidated several similar responses from other members. You write; "I could correct all six points that you felt you had to share ..." I would be MOST interested to read your refuting of ALL my six points if you have some valid arguments. Throughout my professional engineering life I have always been open to alternative ideas and solutions. So prove me wrong and uncross my wires please. I look forward to your point by point refutation. BTW; as an experienced electronics engineer I always carefully double check my circuits before applying power - so crossed wires are not normally a problem with me. Similar principle also applies to my considered response to your posts. Regards, Doug 😎 PS: did you build your steam engines or buy them? There are some guys on this site whom I admire very much, but can not emulate, who build their own. PPS: Quote "In the fifty years or so I have been involved in this hobby I have NEVER ever installed an electric motor in a boat." Fine, if that's your THING, does come across as a little fanatical though.🤔

CNC boat kits...?

I'm thinking about interchanging boat plans as CNC files - so I'm thinking about the sort of machines people are going to have at home. There are a lot of 'cheap Chinese' machines on EBay for £200 up to about £500 - but these will be used for engraving, and will have cutting tables of about 8" square. Boat s really need a long axis. The Shapeoko is an 'open source' hardware design - much like the Rep-Rap, and the great thing about it is that you can specify the axis sizes - so you can have a machine which is a foot by six feet if you wish. I have just bought a UK kit for one called the eShapeoko - 1m x 500mm - cost about £500. But there is so much to consider - calibrating the machine, choosing a spindle drive, picking a software set....

Fairmile D 1/24 Scale Build

I am afraid that I disagree with the comments about Doug. They do not reflect Doug's comments or intentions. We are here to offer assistance to those that request it and others that may learn from the comments etc. Doug offers some of the best most practical advice from his experience. A Fairmile D had 4 engines and props. if you want to recreate it as a true scale model then that is the the aim. You are entitled to have one prop, one engine and one SLA battery in your boat. it may plane for approx 10 minutes before it slows and drops off the plane. I had such an arrangement a few decades ago in an old MTB, but have learned from it and moved on. I would not advise this arrangement with all the newer motors, battery types and ESCs available. My Fairmile D has 2 x Speed 700 motors and NiMH batteries. it runs on plane for an hour or more. My newer Vosper MTB and La Combattante III boats have 2 x brushless motors each and the same NiMH battery packs - my choice. Other people use LiPo batteries. We respect all s and their quest to build 'their' own models. Nothing wrong with having the best advice available, so s can make up their own minds.

CNC boat kits...?

I'll probably go for a laser cutter in the end. A big CO2 one - but these are powerful tools, and i'd like to have a reliable cutting bed before experimenting with something that might cut the shed in half! The obvious answer is to use some driver software that does handle tool radius compensation - I understand that the Tiny board firmware is now open source with a new name - G2Core. I think it needs a bit more poke than an Arduino Uno, though. I intend to simply slot sheets of balsa into it and crank out kit parts - which means a single pass cut. One issue is how to hold the sheet of balsa down without interfering with the cut. I was wondering about a vacuum base. If you want to observe a laser cutter safely, I hear that the Yank s are sealing them in enclosures, and viewing progress through a webcam, which is one answer....

Assembling the keel & adding bulkhead formers.

Hi Mike. The majority of Phil Smith's Veron designs were around this principle, just as the Aerokits/KeilKraft designs were based on the 'egg crate' method. Both methods are very successful and popular over the years as many s will attest, and the hull can be completed really quite quickly. 'Plank on frame' is probably as common if not more and a great deal more time consuming but far better able to reproduce complex hull shapes. Never tried the latter..perhaps one day.

just need cable (wire)...

Gents, I wanted the soft floppy silicon covered wires, so Halfords wouldn't do. Doug, the odd thing is that when I worked in Germany as a clay , I was often given hard modelling jobs (not clay) which usually meant making complex little mechanisms. So much so that I became known as Mechanical Martin or just "Mekanist". Yet back home fitting all the worky bits to a model boat or even a slot car/model railway loco is the bit I hate! Don't know why, except maybe in the boats/slotcars/locos there is a certain way of doing it which I find a drudge and in the clay studios there was always an element of invention required. indeed I am the nominated inventor on a VW patent! But, I have run out of space for storage boxes and can only rarely get to a decent pond to run anything, so I am going over to static models only now. 1/24th scale models of mahogany hot rods (woodies), some in scenic set-pieces, maybe. But I'll finish the models I have on the go first. Martin

Rudders and Propellers

BTW; I copied your above massive text block into a document file and split it up into paragraphs so I could see where you're at! My conclusion: so far so good BUT! You made the one classic mistake of many model boat / ship builders 🤔 You continued the prop shaft tube right back to the propeller and hence you had to make oversize struts to support them. This is fundamental wrong and creates unnecessary work.😉 On real ships, including the Schnellboote, the so called 'stuffing tube' is JUST THAT, it 'stuffs' the shaft through the hull and includes stuffing glands to prevent the ingress of sea water. Outside the hull ONLY the rotating shaft itself continues on through the bearing in the support strut and to the prop. See attached pics of my HMS Belfast as an example. There was actually no reason for you to make oversize strut bearings, simply bushes to match your prop SHAFT not the tube would have been correct. Inside the real ship there is also NO TUBE, only bearings at suitable intervals. They look like gigantic versions of the big ends in your car. Imagine on really big ships, carriers, container ships, bulk tankers etc, with shaft diameters of 1metre or so how big the 'tube' would be, how much weight that would add and how difficult it would be to service and maintain! I've often noticed in posts here that folk confuse shaft and tube, often referring to the whole assembly as 'the shaft'. For convenience we s use prop tubes, who wants to fiddle about making a row of internal shaft bearings no one will ever see and will most likely never be really concentric? The downside is that continuing this 'convenience' outside the hull is wrong, adds weight and detracts from the scale appearance of the model. 😭 OK, it's 3am here now so - orf me 'obby 'orse and up (in my case down!) the wooden stairs to Bedfordshire, G'night all, cheers, Doug😎 Re shaft length: What fits fits, what don't don't! Such a question is like asking 'How long is a piece of string?'! If all three motors abreast won't fit you have to decide if the central motor should / will fit fore or aft of the outer motors. Then measure / adjust the shaft length accordingly. Before you start fitting the centre motor check what length shafts are commercially available and adjust your motor fit to suit. Otherwise make your own shafts and tubes to fit as required, as I've started doing cos I got fed up with 'standard sizes' wot don' wanna fit my ship. 🤔 G'night All, cheers, Doug 😎

Devil in the detail!

I'm with you there Skydive 👍What Boatshed means is the part of the rudder in front of the stock. Thinks: are you building an Offshore Power Boat or a scale Lifeboat? If the former then follow Boatshed's recommendation. If the latter and the rudder is 'scale' then leave it alone. Any braking effect, which usually is only significant in a fast racing boat model or other fast planing types, can be diminished by reducing the rudder servo throw at the TX. One should also consider how the original behaved, maybe they did 'dig in' maybe not. There has to be a reason why such rudders were developed, and surely not just to annoy s 😁 One more minor point that struck me - Ouch 😭 Your prop struts! "not that it provides a huge amount of support but adds to the scale appearance." Even in a model they can be important. To help reduce potential whipping of the propshaft, especially if the model is overpowered. Actually in the originals they were vital, especially in larger vessels. The purpose of these struts, in larger vessels 'A' frames, is to provide support to the end of the shaft which carries the prop weighing several tons and, more important, to carry the bearing for the outer end of the shaft! Actually in the originals the shaft tube, or 'Stuffing Box' would not extend significantly beyond the hull. Thus the strut or A frame was vital for the shaft end bearing, fitted immediately in front of the prop for maximum stability. Attached pics of my HMS Belfast (sorry don't 'ave nutt'n smaller with this feature🤔) show the arrangement. Have witnessed such construction in various shipyards around the world. Last one in UK was the first T45, quite an experience! 😲 In the end she's your boat, if it feels good do it! 😉 I would leave the rudder alone if it is 'as fitted'. 👍 I make my struts and A frames from brass sheet and tube. Cheers Doug 😎 PS Stick with the brass Donnie! 👍

Graupner Elke HF 408

BTW Allen, Dave's comments re 'old motors' go in the right direction but the basic thought and measurement technique are not quite right. There should never be ANY ohm meter reading between armature coils (i.e. motor supply connections) and case! Do by all means try this, but anything less than infinity, '---' on most digital meters, means a scrap motor😡 This test really requires an insulation test using what is commonly called a Mega meter. This has a crank generator which puts high voltage (ca 1000V+😲) across the unit under test. it measures the insulation resistance in millions of Ohms, hence the name Mega! For us s not a particularly useful or practical test! The most common form of deterioration in old motors is cracking and flaking of the insulating varnish of the armature windings. This does not normally cause shorts or spurious measurable resistance to the case but causes internal shorts in the windings thus reducing their resistance and therefore increasing the current they draw for a given voltage applied, as Dave indicated. There are two ways you can check this, if you have a decent Ohm meter, one less, one more accurate. The less accurate is done externally by measuring across the normal motor connections and thus include the resistance of the brushes and connections. Connect the meter where you normally connect the output from the ESC. Slowly rotate the motor so you can feel the slight 'click' as the motor moves from one winding to the next (or one magnetic pole to the next if you like😉) You should see a few Ohms resistance at each pole. Value depending on the quality of the carbon brushes. Better quality brushes (more copper content) = lower resistance. Note and compare each 'pole' reading. If one 'pole' reading is significantly lower than the others then that winding has an internal short😡 The motor may overheat in that winding, depending on how many wires are affected, and fail eventually. The more accurate method is to dismantle the motor and measure the winding resistances directly at the commutator, i.e. without the brushes in circuit. But this is only useful for nuts like me 😁 as in my 50 year old Taycol Target renovation. I was lucky no shorts and all windings same resistance + or - a gnat's whatsit!😊 Sooooo, to cut a long story sideways😉I think it's very unlikely your motor has any internal problems. I recently found one of the ancient Mabuchis I originally fitted in my HMS Hotspur destroyer 51 years ago, it still clattered along, bearings shot but electrically still OK 😊 Just take what you've got now down to the lake and give her a Go. if she looks right then she most probably is! As my German colleagues would say "Always a hand's width of water under your keel". Cheers Doug 😎 PS: "But trust me on the sunscreen" 😁
