Slow going ... by BW3 Chief Petty Officer   Posted: 5 days ago
After building the mine laying rails I then purchased scale German mines , only to find out that they are 4mm wider than the rails on the boat, ...what to do , cut the mines (8) down and rework the base and wheels to fit the boats rails or move the rails wider ..... moving the rails ... slow going , found that the motors I have are more aircraft/drone use per the esc, , no reverse .... Hobbyking does have esc that will work , still need a couple of servos and a radio , just not sure if a 6 Chanel land/ boat radio or get a large channel stick radio would be better ... as always $$$$ is an issue . Work on the messy table as I fit cut and replace fittings and supports ... Smooth sailing to all... Bill G

HMS BRAVE BORDERER by kevinsharpe Sub-Lieutenant   Posted: 10 days ago
Hi. Been watching this build progress and the discussion. Having seen the recently posted pictures of the rudder installation it appears that your problem is probably caused by the rudder aspect. From the photos it appears that the rudder post is not mounted completely vertical. Thus when the blade is turned by the servo this will create an aileron or elevator effect on the water flow. Things behave very. Much the same in water as they do in the sir. Regards Kevin

Smoke generator by jbkiwi Commander   Posted: 11 days ago
Have just made a prototype of a fan forced smoker which seems to be working well (despite breaking the heater coil by moving it while hot, - had it apart, broke wire, screw and washer repair, not quite as hot) I bought a couple of Heng Long smokers (for R/C tanks or cars) to play with, for $10 NZ each(or 5.3 Euros to you Northerners give or take a yen) from Bangood and just bought another from Ebay. There seem to be 2 different models, as one has a long coil with a lamp wick draped over it, which is sitting in the oil reservoir, the other has a small coil inside a piece of heat resistant woven tubing (as you might find insulating toaster/heater wiring etc) which acts as a wick and that also sits in cotton wool in the reservoir, (this seems to be the better of the two) Tip - don't fill the tank right up, only enough to soak the cotton, element should be just out of the oil. The wick loads the element. The better model seems to have a black top to the tank (also maybe either brown or black tank) and the other has a brown top and dirty brown tank. As with most of this stuff you won't know till you get it what it's going to be. What I did was remove the tank and cut off the pump tube just in front of the screw lugs (see black line in photo) then fitted the tank, and a 40x40x10 5v ESC fan (voltage controlled by a UBEC set to 5v on the jumpers) into a plastic electronics utility box from Jaycar (our local electronics and hobby store). I made up a double JST lead for the 2s 1800Mah Lipo and fired it up (using baby oil). It's pretty much silent and smokes well once it gets warmed up, ( starts smoking in about 5 seconds) You could control it (on/off volume) by either a remote on/off switch or perhaps a small cheap 10A brushed ESC. I would leave the fan running and control the element to avoid burning the element. The original pump tank inlet hole seems ok as is (approx 1.5mm) but you could enlarge it very slightly to get a better flow if you could find a better oil. At the electronics store they have proper smoke machine oil for $20 NZ per litre so I may have a look at that. The reason I went for the fan idea was that I found in std pump form, if I immersed a tube from the tank in water, it sucked water back into the tank. I was hoping it would pump smoke out of my HSL exhausts at water level alongside the cooling water but it would need a very light non return valve to do this. The fan seems to pump the smoke through 2mm ID silicone tube ok, so tubing of similar ID to the OD of the tank outlets should work well. These pumps in original form work pretty well for the price, and are cheap enough to keep a few for spare elements, the only thing is they are a bit noisy but in an 'engine sounding' way, (might add to the effect on a tug or work-boat though) What you have left after this mod is a very handy little geared motor with an eccentric output wheel which could be used for winches, radar and whirly bits of any description (see pic of motor leftover and original) To avoid burnout, these should be run on no more than a 2s (around 7.5v-(suggest 8v max with fan running) The other tank is going to work a lot better than this one but I'm not making a tug, just want a bit of exhaust smoke on start-up etc to go with the 2 sound units. Very cheap to make (around $25 NZ with pump, box, fan and UBEC all through Ebay, Aliexpress and Bangood (and local electronics store) If you wanted to run an ESC to control the smoke and you have no channels left to control it proportionally, you can always try using a second receiver bound to your TX, (if your TX will allow it,) power it and a brushed ESC (wired to the element) as normal and use the throttle channel to plug in your smoke control. This should work if you want more smoke as you accelerate or if you are using only 1 stick on a 2 stick TX you could use your 'elevator' stick pushed up (or a toggle switch if available) to start/stop the smoke (through the brushed ESC setup) . This setup weighs 100g (10g more than std) The quest for lots of smoke continues Will try to upload vid later and update progress.

2nd servo fitted and copper pipe through round hatch all i need to do now is make the control arms to to operate main and for sails (photos to follow )

Decks & hatches. by robbob Fleet Admiral!   Posted: 15 days ago
Because I need access to the wiring at both ends of the boat I formed the framework of an opening at the bow to make the dummy hatch into a real hatch. In a similar way a hatch was formed in the rear deck which will give me access to the wiring, rudder servo and the ESC cooling. It’s going to be quite tight to get all that into the cavity under the rear deck but I’ve done a test fit and it will all go in but will involve some ‘keyhole surgery’ through the rear hatch opening when I get to the stage of installing all of the running gear…🤓. Both of these decks were glued and pinned in place and some packing tape used to pull the decks firmly onto the frames. The side decks were also trimmed for best fit and secured in the same way and when all was dry and set a small hand plane was used to trim them flush to the hull sides. The next stage will be to fit the balsawood blocks at the bow and shape them to the hull…..it’s the tricky bit I’ve not been looking forward to…😟

Propshaft Lubrication by Joe727 Captain   Posted: 17 days ago
I use White Lithium Grease in my stuffing tubes and on both plastic and metal gears. I build my own stuffing tubes for my 3/16" shafts using bronze bushings from the local hardware store. They insert into about a 3/8" brass tube thereby giving a reservoir for the grease. Does not seem to breakdown at all, has a nice viscosity, does not damage plastics and I have read will tolerate high heat. Local auto parts store sell it for about $6 in a tube that lasts me for years. Just my experience..... Joe

Deck, servo mount by Joe727 Captain   Posted: 23 days ago
Put together a pilot house based on some tugs I've seen. Just freelanced it as I went. I build a lot with styrene so I am used to just cutting and building. I use liquid styrene cement that fuses the materials together. See photo, will trim it out as I mount it, need to add some detail at roof and some Navigational lighting. Put on on 3mm plywood deck, same as hull bottom. The deck is also curved (proper term is SHEAR) and I started to build up some wood edge at the opening. Will sand everything well, then start sealing and priming all surfaces. Made a bracket for the rudder servo mount and an adjacent platform for the ESC and RX. Ordered two 6v 5ah SLA batteries. I will wire in parallel to stay with 6v and get 10ah. I like to stay with 6 volts as I want the motor to run slow like a tug should. Will wire in an in-line fuse. Haven't decided where I will put switch, up high somewhere to avoid water. I will show the wiring once I get to it. This build is going fast because it's a simple design, just what I was looking for. I work on it late afternoons and into the evening while I watch basketball games. About 4 hrs a day. Looking forward to building the hatch and getting some primer started tomorrow. Regards, Joe 👍

Internal wiring & bottom skins by robbob Fleet Admiral!   Posted: 29 days ago
There's plenty of access to fit the rudder tube at this stage because the deck skins have not gone on yet, and I still have fairly nimble fingers 🖖 😜 I'm generally following the kit instructions but I have sufficient experience to 'plot my own course' and deviate from them to achieve the same or better result. A great deal of thought and forward planning goes on when I build anything so I don't usually 'paint myself into a corner' so to speak. Here's a 'sneaky peek' (see pics) at the rudder and servo location that I'll cover in detail in the blog shortly. Happy Crimbo to you and yours 🎄 🎅 ⛄️ Robbob.

Internal wiring & bottom skins by robbob Fleet Admiral!   Posted: 29 days ago
Because I am keen to conceal as much of the wiring as possible I have decided to place the battery at the bow and the operational equipment at the stern, the engine on the original boat was central and covered with a soundproof box and this is convenient as the motor can be positioned and concealed in the same way. This means that some of the wires will have to run the full length of the boat and the easiest way to conceal them is to run them beneath the ‘box’ around which the hull is formed, and this needs to be done before the bottom skins are fitted. Holes were bored through the bulkhead formers under the port side of the hull and battery cables were run to the stern where the ESC will be and three motor wires from the ESC run to the centre, emerging near the motor position. For good measure I put in a servo cable and a separate draw wire just in case I needed to put more cabling in for any additional features, perhaps working navigation lights? Satisfied that I had all the cabling in place I was able to fit the bottom skins starting with the starboard side first. Before doing so I put a very slight 'hollow' in former F1 which should help blend the shape of the the hull where the ply skins meet the balsa blocks that will to be carved and shaped to form the bow. This can be seen in the last picture. The process of forming and fixing the skins is the same as for the side skins but in addition to the pins holding the skins in place I used some brown polythene ‘packing tape’ to pull the skins tightly against the bulkhead formers and strakes. The packing tape has a very high tensile strength and is ideal for this, and of course cheap and easy to remove. Once the aliphatic glue had set thoroughly overnight I removed the excess from the skins with a small block plane and finished them with my sanding plate. Before I fit the skin at the stern I will have to arrange the water cooling for the ESC, with the pickup just behind the prop and the outlet on the stern. I’ll cover that aspect in the next update.

Ship rudders by Toby Lieutenant   Posted: 1 month ago
Almost there. Have to turn some hinge pins and seal about the rudder access in the hull. Then to work out best method of rc linkage from rudder to servo. T

How to RC small boats? by DodgyGeezer Lieutenant   Posted: 1 month ago
There's no great need to dismantle a servo to get motive power - nowadays you can buy model motors that are not much thicker than a typical boat propshaft, and speed controllers the size of a thumbnail. Usually for about a pound. These small drones have really helped in this regard. This one, for instance, is 0.6cm diameter by 1.5cm long - https://www.ebay.co.uk/itm/Original-JJRC-H20-RC-Drone-H20-08... Your biggest problem will usually be rudder control - there will be little room for a servo and tiller right at the stern of small boats. For an EeZeBilt I recommend a closed loop system which lets you relocate the servo anywhere convenient - see http://eezebilt.tk/radio.html The EeZeBilt Terrier below is 10.75 inches long...

http://www.mhsd.org/model/howto/ style='background-color:yellow;'>servo.htm Anyone done this? Please send me some pictures of your work and anything I should be cautious about when putting this in a small craft? I want to put a small motor in the Comet sailboat and run it with the sails furrowed.

small servo's by jacko Commander   Posted: 1 month ago
thanks bike spokes looks / sounds great but then found out a 1.6mm drill works ok this morning as a 1.5 was tight,, drilled holes 1 3 5 one side and 2 4 the other thanks for all input

Agree with Doug. I use bicycle wheel spokes. Got an old wheel from my local bicycle shops scrap pile for free. Got enough rods now for the rest of my life!

small servo's by RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi Jacko, So what's the problem!?😉 Drill out the servo arms to match. Or; forget the clunky commercial clevis pins and simply make a push rod from spring steel rod. Don't let the manufacturers dictate to you!! Use your imagination; and a couple of pairs of pliers 😁 Cheers, Doug 😎
