EarlyVosper M.T.B by Simplas by boaty Captain   Posted: 6 hours ago
Hi Onetenor Fuji 15 was a good glow engine which I don't think it is manufactured any more. Aero version max B.H.P was just below .40 when tested. If it was in a model aircraft it would have been around .20 to .25 depending on prop size which was good then for a small capacity glowplug . Marine versions when on the water put out a little less and the water cooled jacket was never as efficient as the finned cylinder jacket of the aero version. My two Aerokits boats, the Sea Commander and the Crash Tender are powered by single Speed 600 motors running on either 8.4 or 9.6 volt Ni Mh batteries. Performance is equal to that of marine diesel power such as the 2.46 Ed Racer and D.C 2.46 Rapier, the latter I used to watch in the fast steering events in the early 1960s at Fleetwood and Coronation Park in Crosby just outside Liverpool. Taycol powered versions would be obviously slower due to the additional weight were far more reliable and you did not have to put up with injuries from excessive use of a starting cord with kids watching and "extracting the urine" shouting "why wont it go mister".

"Maybe but ballast ,is ballast,is ballast. However it's achieved." Sure John, but at least a heavy battery is useful load and not 'just' ballast.😉 Have no idea what shaft power the Fuji produces (only know their excellent 35mm film😉) but the Taycol Supermarine is rated at 22.5mHP (22.5/1000HP) at 3.5A, 4000rpm. Efficiency 52% 🤔 so you have to stick twice as much electrical power in to achieve that! Sooo, given that 1HP = 745.7 Watts - And electrically P=IxV (Current x Volts) 22.5/1000HP = (745.7*22.5)/1000 = 16.778W so ~33.55W in. Thus if I = 3.5A they must have done that test / measurement at about 9.6V. The Supermarine also runs great at 12V but maybe not with max efficiency!? With a spec weight of 2&1/2 lb i don't even want to get into Power to Weight Ratio, although I measured Colin's motor at 947gm = 2.0877776229lb 😉 But then, some of the motor had corroded away As I'm currently renovating a Supermarine for Colin H. This makes me start thinking about rigging up a test jig so I can see what it actually produces!!! Always up for a challenge 😁 Got nowt else to do 😁😁 Would be useful for other motors as well if I can get it figured out😉 Happy fiddlin' folks, cheers, Doug 😎

Maybe but ballast ,is ballast,is ballast. However it's achieved. The overall effect is the same. Would the Taycol Supermarine have had more power than the Fuji? Or at least the equivalent.?👍

Hi Martin, Apropos mini Milling machines; this is the one I use. https://www.youtube.com/watch?v=qffdG_d2fJ0 https://www.axminster.co.uk/proxxon-mf-70-milling-machine-37... Pics show using it to mill my new Sea Scout propshaft to secure the grub screws in the motor coupling. I just changed the tool holder from collets to a proper chuck. I also bought the little machine vice which clamps to the table, and the dividing head. There is also a CNC (putah driven version - ain't got that far yet, bit expensive😉) But this little job has served me well for several years now, very happy with it👍 I also use it as a precision drill press; e.g. to make the new phosphor bronze brushes for my Taycol target renovation. See last pic. Have also recently used it to make the little gearbox so I can fit the renovated Taycol Target into my ancient Billing Danish fish cutter 'Gina2'. See, I don't just do the 'Grey Fleet', sometimes I also mess with wood😁 Cheers, Doug 😎

Shucks! An I was hopin' you'd build me a little 4 cylinder diesel for me to run a brushed motor as a Genny for all the lighting on my ships! Or for the diesel electric propulsion on my Type 45. Now wouldn't that be cool!?😁 BTW Some of Nick Carters tips an tricks showed me how to convert one of my tools to something that'll do what I want! So, out with the Proxxon mini-grinder😉 Cheers, Doug PS It wasn't a wrong steer cos it led me to all sorts of useful 'stuff' and above all helpful info👍

Wha? I bet it's that bloody Post Office crap, where some peaked hat wants money off you for a parcel. Well, in that case, you have to deal with Peatol, who are OK, but not sure if he sells all the goodies that Carter make and sell. He actually remembered selling and delivering mine in an MG Metro Turbo, red and black. After 30 odd years he recalled me living by a river and taking away the Emco PC pile of dog turds in limited P/ex. I would love their milling machine but that ain't cheap like the lathe. I'm never gonna get to make my working model petrol engine, dammit! Sorry to wrong steer you, Doug. I had no idea they'd stopped selling abroad. I would just get my mate in Cal. to buy and send it on to me. Cheers, Martin

Be more careful with your hammer then 😡😭😁 Carter don't ship outside US and Canada so I had a look at Haig and from there to Peatol! Veeery interestin'. Useful stuff. Like the tips an tricks on the Carter site though, excellent. Cheers, Doug

Hi Martin, Reckon bushes are worth a go, can't be worse than two thicknesses of Paxolin! Thanks for the Carter tip 👍 I'll look 'em up. Cheers, Doug

Found on E Bay but sold in June of this year, a 42 inch kit of a Simplas Marine Construction Vosper M.T.B. It would appear that there are not many about now. I built one in 1972 and the kit contained a fibreglass hull with all fittings including the guns being in cast metal. Deck and superstructure were plywood and the boat was a model of an early Vosper as it had a very narrow beam and torpedo tubes were towards the stern. I fitted a DC Sabre 1.5cc diesel but had to add a lot of ballast which resulted in a sharp drop in performance. This was solved by replacing the Sabre with a Fuji 15 marine version glowplug engine . The boat was free running and as I was on an apprentice engineers pay and could not afford r.c.as I was having to support an ageing Mini. This was my transport from Ellesmere Port to the boating lake in New Brighton. If I had bought a Taycol Supermarine motor it would have solved all my problems as the battery would have been the ballast. Boaty 😁

Ah, some of my Taycols are also plastic capped, so nice move trying to fit brass bushes invisibly. BTW, if you're after small tooling for your lathe, try Carter Tools in the States who deal in Taig lathes like mine, although I got mine from a company called Peatol. Cartertools are a great company and sent me spares for a very good price when I needed a new drive belt and an indexing attachment. Cheers, Martin

Mornin' John, agree re chromite, but still don't know what chroDite is! I only personally own the one Taycol Target. I got into this whole Taycol business while I was renovating Dad's old Sea Scout last year and decided I wanted a bit more Oomph so upgraded it to a 1000kV brushless, which gives goods results on a 3S LiPo. See the vids I've posted of the the 'Sea trials' (Lake Trials!?). So I decided to use the Target in the ancient Billing Boats Danish fish cutter I'm restoring and converting from static to RC. Figured the Target would cope OK with the plodding pace of a fish cutter😉 BUT, I wanted it to be reversible without cumbersome external switches or relays as recommended by Taycol / Keil Kraft in those days. After surfing around a bit a found a website where others had tackled the same problem. Looked at their solutions and refined them slightly. All I do is rectify the pulsed (square wave) signal from the ESC with a bridge rectifier (4 hi-current diodes in a bridge form in one package), apply the + and - outputs from the rectifier to the field coil so that it produces a constant magnetic field just like the permanent magnet of a canned motor. The two alternating (pulsed) outputs of the ESC are applied to the AC (~) inputs of the rectifier, which go + / - or - / + according to the command from the TX, I apply to the brush terminals just like a normal brushed motor setup. The output of the ESC is a train of either positive of negative going DC pulses. Pic 2 the positive train on the scope. Pic 3 the negative train. The larger and wider the pulse the higher and longer the voltage is applied and the faster the motor spins. So called Pulse Width Modulation (PWM). The gaps between the pulses are smoothed out by the inertia (flywheel effect) of the motor, and anything hanging on it - like a prop and a few million gallons of wet stuff 😁 Hey presto, a field coil motor that runs forwards or backwards on command 😊 Main thing is simply to separate the field coil from the armature coil (i.e. brush gear) so you can control each one independently. No rocket science but highly satisfying when it all comes together and works on the pond. OK, I'll look up Mr Lynch, wasn't he the Sarge in Z Cars 😁😁😁 Cheers, Doug 😎

I too thought Chromite Doug but can it be used on it's own? I've only heard of it as an alloy or a catalyst. BTW great job. Never owned a Taycol but seen loads.👍 You don't recall Lynchie Tut tut😁
