Hi Sakibian, The PT boat site now sells stuff too, but was originally a site where the author John Drain described how he was building his PT boat and then the E-boat. There are good plans and examples of how he has constructed these boats. My Fairmile D was made from plywood frames, pine stringers, planked and skinned with balsa and then fibreglassed. It was a very interesting and difficult shape, but very satisfying once completed. It sails beautifully in the most difficult conditions. I have also included a few more pics of my friend's E-boat with the newer camouflage for further inspiration.
Hi John, You seem to have missed the point entirely, as you also did with your first post on this thread, in which instead of trying to help Andy and answer his question you attempt to dissuade him from his goal. Unfortunately I missed Andy's question back in March as I was embroiled with family matters. BUT, if he hasn't in the meantime been 'scared off' by the lack of constructive response I will do my best to help, having several times been down the road of multiple screws, as have many other better constructors than me on this site. Nearly all my ships have two, three or even four screws. Only the Sea Scout and ancient Billing Boats fish cutter (a restoration and conversion from static to RC project) have single screws - as per originals. About a year ago I acquired a model of a US Elco PTB fitted with two shafts. I am restoring it, rebuilding as Kennedy's PT109, and will fit the third shaft to complete it to scale as per original. Why? Because that's what scale modelling is about and because it's a challenge - pushing limits. Far be it from me to decry or put down anyone (as you now seem to be trying with me). We all have the enthusiasm (or we wouldn't be here) and do the best we can with the skills nature gave us and what the budget and state of health allows. I have often been astounded and appropriately applauded, and supported where I can, what fellow members have achieved with very limited resources and under very different circumstances from those we in the so called 'Western World' enjoy. That guy in Bangladesh blows my mind with what he manages in the back of beyond! Look for his post about his March '71 boats. WHEN I pitch in here I try to do so with constructive assistance, drawn from my own modelling experience and a lifetime spent working with navies and shipyards, to help a guy achieve his aims and dreams. NOT to immediately deflate him by saying 'Why do that? I did mine this way, it's not what you want but it works for me'. So far the Likes, PMs and mail feedback, request for assisitance I have tell me I'm doing something right. If I do boob (we're all human) I'm prepared to admit it and make amends / corrections. I have no idea what this 'Hooben' is that you yatter on about BUT - if "every little detail (is) reproduced with superb accuracy" why then ruin the overall effect by not continuing this attention to detail on the underwater ship and fitting shafts and screws appropriately? Whatever you do have fun with it, but don't dissuade others from pursuing their dreams. True there are "many roads to travel before one reaches there (!sic) destination" BUT as Confucius said "Every journey begins with the first step." If at the first step someone says 'Your destination is the wrong one' instead of offering a roadmap ..... ! Regards, Doug 😎 BTW: still waiting for the pics / videos of your 'Hooben' (?) and the Perkasa.
Hi biker, Depends on whether you want to build true scale model and build it 'right', or just a near scale 'Runabout'. Rowen has learned (with a little help form his friends 😉) to build it right which is extremely satisfying and the correct detail underwater truly compliments his superb detailing above the waterline. To me the two are inseparable. Seems to me that that is what Andy wants as well. I applaud him. About time we gave him some constructive answers - but first we need to know something about his boat:- Length, beam, probable max weight? If all you want is a near scale quickbuild fast runabout John there are plenty of ARTR/RTR options on the market. But then; that's just my opinion - and whadda I know!😁 Look forward to at least some pics / vids of your boat in action Biker. Cheers, Doug 😎
The heating elements in the hairdryer had two different wire gauges as elements. I removed the lighter gauge thinking they would probably draw less current. I am attempting to use 6 volts as that is what my boat is. 1. First Photo: Took a length of element and stretched it out as shown, started with a longer piece about 8". If you are at 12v probably longer. Use some alligator clip jumpers and attached to one end, ran it to negative terminal of my 6v SLA. Took another jumper and attached to a point on the wire, say about 7". JUST TOUCH the other end to the battery positive to see if it glowed, it did not. So just moved about 3/8" at a time till it glowed - See Photo. CAUTION, make certain you have a nonflammable surface to work on, I used a tile scrap. IT GETS HOT FAST AND WILL BURN, DON'T ASK ME HOW I KNOW. That's why I just touch the terminal till it glows then stop, let it cool for a while. 2. Cut element to length, than take your 16 gauge wire and the crimp tube shown in earlier post. Insert both into the tube and crimp it. I used a side cutter and carefully just squeezed enough. Make sure that the element will not pull out. Do the other end. Because I am using only 6 volts, I had flattened out the wire to give me more wraps on the wick. See photo and note. 3. In the lid of the box, I located the fan at one end, the exhaust stack at the other. Drilled a hole matching the fan opening and secured with two screws, drill small pilot holes so as not to crack the plastic. Drill hole to match brass tube OD, tube is about 1" long or so. Super glued brass tube in place. Excuse the sloppy copper sheet work on the inside of the lid, it was an experiment at the time. I added this a a bit of a heat sheild as the wick and element would sit below this. 4. Next photos show the interior of the box, not the best photos of the process as this was already built.... The mint tin set inside the plastic box was an idea to do two things; first isolate the heating element from the plastic,and two, provide a smaller vessel for the fluid. You may want to just use a metal container instead of the plastic box, again I was just using what I had on hand. The wick is laying in the tin with the element propped up at on end to keep it out of the fluid. Photo shown does not show much fluid in place. This needs some work, but worked for this test. Experiment, just be sure that the lower portion of the wick is in the fluid and the element wire wrap is above the fluid level. For the test, I used some mineral oil and a bit of glycerin, smoked very well. It's late so I will run it and photograph tomorrow. Cheers, Joe (Excuse the Imperial rather than metric)
Nice one 'Cyril' 👍 Used much the same technique for the spray rail repairs and replacements on my PTB 109 restoration. Works a treat don' it. Pics show the before an' after. Following the build with great interest, as I also did the Fire Boat Rob. Great stuff. Keep it up. Cheers Doug 😎
Hi all, in case anyone bothered to wonder where I wuz, you may know I was making a master for a 1/6th scale model kit of a Vincent Black Shadow 'bike. I sent the engine casings to Griffin Moulds in the Midlands and they utterly destroyed the masters, sending me back a back of fragments! No phone call, no e-mail, no note in the late-delivered (DPD) parcel. Now they have the cheek to invoice me! So I have been busy catching up with other stuff kept waiting for a while, sucvh as a 1/43rd scale brass master of a Triumph Model H 1915 'bike and a 1/32nd scale Vanwall Transporter. So I haven't even looked a t a model boat since the weather turned. And likely shan't much before May. Everyone have a nice Christmas. Cheers, Martin
The 37th Annual Modellers Exhibition will be held at The Grange Centre, Bepton Road, Midhurst, Sussex GU29 9HD on Sunday 10th February 2019. This is a great exhibition in the South where many Model Boat Clubs attend displaying a great array of their boats. For the train enthusiasts there is a large hall with fantastic displays and trade outlets.
Hi Doug. All credit due to Phil Smith and his original design for that actually... Hi rolfman2000 I hope SWMBO is good to her word as I happen to know that the kit is now available to buy from Vintage Model Works 😊👍 I'm told the price is £185.00 + P&P and there's also an optional stand/carrying box which is CNC cut to the hull profile for an additional £10.00 That sounds a bit of a bargain too. Contact Mike Cummings at VMW for more information: http://www.vintagemodelworks.co.uk/ I'm hoping to have the boat in an advanced state of completion in time for the London Model Engineering Exhibition at 'Ally Pally' in January 2019. It will be on the St.Albans & District Model Engineering Society club stand alongside my RAF Crash Tender. Rob.
I am not sure that you mean 'latex'. The most usual soft tubes are silicone rubber. Not neoprene, as it is usually too stiff. There are all sorts of universal joints available. Here are some metal ones from Ebay: https://www.ebay.co.uk/itm/5x-RC-Model-Boat-Robot-Universal-... These are surely too strong for small boats, however. The Eezebilt range are typically 30-50cm long and I use silicone rubber joints on brushless motors there quite satisfactorily. You just need to be sure that the tube wall thickness is sufficient - typically 3-4mm. Here is a picture of the Eezebilt PT Boat (50 cm long) motor connector, with a picture of it running. You will see that it can go at a reasonable speed. See http://www.eezebilt.tk/PTBoat.html
Thanks for the nice comment, and yes it is a very nice pond, except when there are a lot of those things with rags tied to sticks racing (shouldn't say that as I've sailed full scale all my life and still have 2 small yachts), and the buoys they leave there are a pain also, (easy to forget they are there) It was full of hire carp (yes hire carp) which were removed as the council wasn't paying the company or some such hassle, but I'm sure they missed some and they will soon multiply and keep the weed down. Bought the plans for the MTB around 1968 and took around 20yrs to finish it. I still have the plans and it only took me about 40yrs to find a photo of the original boat (bit late by then!).
Thanks Doug, always appreciate your thoughts. The relays are in a NO mode, so only operate when selected. On the bench works fine. Perhaps you do not have the same modulation issue as you are using 1000Kv and I am 2200. My motors respond rapidly, particularly around the fwd/rev position, so am always trying to accurately centre the lever. The motors I choose have integral cooling jackets and are nicely made. If they had been available in a lower rating would have probably used that. Good luck with the PT boat, looking forward to hearing what you decide with the powertrain. Good luck with the "C" check oug. Best wishes R
Good thinking Batman👍👍👍 I hate those slide switches as well. They're always the first thing to fail on my garden solar lights. Nice trick with the relays, could also perhaps have used one double pole relay to replace the ESC switches? Otherwise they are energised but in an 'undefined' state 😲 Strange, I don't have your 'modulation' problems with the brushless (1000kV) in my Sea Scout!? 'Get-home'; agreed 👍, that's why I'm pondering squishing a centre motor into my PT Boat. It's all stripped out and in the 'C Check' dock 🤔 so now is the time! All the best Rowen, cheers, Doug 😎
[Score: 8/10] 40" Loch Ranza Capable of 3mph and a runtime of 100mins Geared to a MFA 919D series Powered by Lead Acid (18v) Batteries - Comments: I bought an unfinished Graupner paddle steamer kit which was in a bit of a state and spent many happy hours making her look loved. The hull and paddle wheels were in an acceptable condition but the deck and superstructure left lots to be desired. The previous owner had purchased the motor which was 50.1 geared and pushes the boat along well all other bits including 'smoke' brass portholes and new superstructure added by myself. She was a delight to finish and looks an absolute dream on the water.
Hi Samnewbie I have a Cariad which is wooden hulled at twice scale. I decided to use a false keel but as I bought the hull completed needed to retro-fit one. I agree with you! If you can fit the tube as early on as possible it will make life a bit easier. My keel needs to be about 12kg and the tube is a couple of inches behind the mast. I am still trying to cast the keel; I'm now on my fourth attempt! I have calculated the keel weight and plan on it being about 1kg lighter than need be. This will allow me to finely trim the boat up once complete. Good luck with yours. Edward
