Vinyl lettering by RNinMunich Fleet Admiral!   Posted: 2 hours ago
Hi Manofkent (from a fellow man Of Kent! Folkestone😉) If you have an inkjet printer and the Bliss font on your PC (downloadable I expect) you can make your own decals, any scale you like, with printable decal film. For instance, found on Amazon- https://www.amazon.de/dp/B00835TC7Q/ref=pe_3044161_185740101... Must also be on Amazon UK. RM Logistic UK Limited 20 Carville Grove Wigan WN2 4NN GB I made the name decals for my Sea Scout with this, using Winword on the PC. Cheers, Doug 😎

We should live so long Ed 😉 I may have the machines necessary to make a steam engine, but I sure don't have the expertise necessary🤔, like Hammer 👍 for instance does have! Anyone out there making mini marine diesels???? Cheers, Doug 😎

Thanks Ron, the learning curve is steep but I'm getting there 😉

engine by RNinMunich Fleet Admiral!   Posted: 9 hours ago
Hi Hammer, that's exactly why I use my mini milling machine for such precision drilling tasks! Work piece clamped in a machine vice bolted to the table. Start the hole with a small milling bit, for such a key slot as yours simply continue with the milling bit. I will be using this method on my Gina 2 cutter to key the gears to the shafts. If a hole is required the drill bit can't skid off😉 Drill slowly with cutting oil!! Cheers, Doug 😎

Harbour Posts - Again!! by RNinMunich Fleet Admiral!   Posted: 18 hours ago
Here we go again! Sinbad, Seagull, HMS Dittisham, All sound very interesting- BUT without pics very disappointing 🤔 "Painted in the scheme of ...." A picture tells a thousand words folks! Doug

Hull Pt2: Motorisation - Come What May!! by RNinMunich Fleet Admiral!   Posted: 21 hours ago
As promised (or threatened?😁) stage two of the hull work and thoughts on motorisation. The hull was sprayed with two coats of grey primer/filler. Pic1. As usual this showed up the remaining imperfections (pics 2 & 3), but I'm not going to worry about them until I've got prop shaft tube and rudder stock sorted out and permanently fitted 😉 After my attempts to make and thread a 3mm prop shaft went awry Martin (Westway the Mechanicals Master👍) stepped in and made me a decent one complete with a bushed stuffing tube 👍 Vielen Dank Meister😊 I did however manage to make a 4mm to 3mm reducer so that I could fit a Rabeosch 35mm prop as seen in pics 2 & 3. The tube and shaft from Martin, arrived Saturday an' he only made it on Monday😊, have been dry fitted so that I can start setting up the gears, necessary to bring the drive down to the prop shaft fitted very low down in the hull, and motor mount. Pic 4. Motorisation: (Remember folks - this kit was designed and built as a static model!) I want to use the old 1950s Taycol Target motor which my Dad originally fitted in the Sea Scout which I have renovated and upgraded to brushless. See Build blog 'Sea Scout - Jessica' Many of you will know that the Taycol motors were field coil motors, meaning that they have no permanent magnet around the rotor coil, and thus reversing the battery connections to the brushes had no effect on the direction of rotation, as this simply reversed the magnetic fields of both stator and rotor coils🤔 To counteract this so that the motor could be used in both forward and reverse with a conventional brushed ESC I modified the motor slightly (separated the two coils) and built a simple converter board to connect it to the ESC. Again see the Sea Scout blog for the details of the conversion. Basically; once the field coil and brush-gear (rotor coil) have been separated a simple diode bridge can be used to apply the output of the ESC to the motor. This enables the reversal of EITHER field OR rotor coil polarity, depending on how you connect the converter to the motor. Thus reversing the direction of rotation of the motor. Beneficial side effect is that the diodes also suppress the commutator sparking😊 In my case, with the Taycol Target, I also cleaned, flattened and polished the commutator. Thus significantly reducing the potential for spark generation in the first place! A peculiarity of the Taycol motors is that they all use metal brushes, pressed phosphor bronze strip, so they need oiling! DO NOT oil conventional brushed motors with carbon brushes unless the brushes are exchangeable or you want to have to buy a new motor!!!!! Pics 5 & 6 show the proposed position of the Taycol in Gina 2 and pic 7 the prototype converter board I knocked up to test the motor, together with a Graupner Navy V30R Marine Brushed ESC. Details and results in the Sea Scout blog, including video of the sparks and oscilloscope pics of the drive waveforms before and after conversion! The latter showing the spark suppression effect of the converter😊 Some samples attached - last 3 pics. Pic 8 pic shows a more compact version of the converter, one of a few types I'm doing for Martin's various Taycols as a trade for the prop shaft he made for me and some useful material he sent. Thanks mate👍 Next steps will be 1) mounting the gears correctly on the shafts, requiring the manufacture of a 3/32" to 4mm adaptor and a 1/8" to 4mm adaptor, and keying them to the shafts - Hooray for mini milling machines 😉 2) manufacturing bushed end plates to hold the gears in place, 3) fitting the motor mounting platform. I'll probably borrow from my experiences of real shipbuilding and do this as a suspended 'false floor', i.e. mounted on stiff springs to enable adjustments to optimise the gearing mesh! On real naval ships this is done to improve shock resistance and to minimise engine noise / vibration conduction to the hull, thus significantly reducing the acoustic signature of the ship. Not that I'm tooo worried about being torpedoed 😁 Worth a try😉 Pic 9 shows the cleaned up and renovated Taycol Target motor. Pic 10 shows the drive waveform complete with sparks before modification.🤔 Pic 11 the cleaned 'forward' waveform with the converter board. Pic 12 the cleaned 'reverse' waveform, no suppression capacitors needed 😉 More soon folks, Cheers, Doug 😎 PS Along the way a new keel was fitted as can be seen in pics 1 to 3. The original builder had 'buried' the keel in the hull planking! 😲

Gina 2 Billing Boats Fish Cutter - Restoration & Conversion by RNinMunich Fleet Admiral!   Posted: 23 hours ago
Evenin' Mike, guess you're right 🤔 Bit of a departure for me I admit, and after I'd cleaned all the crud off and realised how shoddy and weak the hull was I wondered if I'd bitten off more than I can chew😲 However progress has been made😊 I hate to be beaten! See next update 'Motorisation - Come What May!' You'll recognise the topic from the discussion on dies and threading silver steel prop shafts😉 I'm multiplexing this project with a PTB renovation and refit! Like most boat modellers 'a glutton for punishment'. Cheers, Doug 😎

BRAVE BORDERER by RNinMunich Fleet Admiral!   Posted: 4 days ago
Bon chance mon ami👍 Don't know what TX you have but you may be able to do the mixing there. If not there are several separate mixer boards on the market. This one for instance; Action Electronics P40D from Component Shop. It's good for both brushed and brushless motors😊 See pdf data sheet. Mode 1 might be good for Brave Borderer!? http://www.action-electronics.co.uk/Mixers.html https://www.componentshop.co.uk/p40e-marine-motor-mixer.html Have fun, cheers, Doug 😎

BRAVE BORDERER by RNinMunich Fleet Admiral!   Posted: 4 days ago
Hi Rowen, Surely with a little ingenuity you could do both? Two shafts with a rudder mixer might be better for manoeuvring anyway 😉 Centre shaft on a separate channel and ESC and you've got the best of both worlds 😊 Cheers, Doug😎

Crash Tender crew by RNinMunich Fleet Admiral!   Posted: 6 days ago
More or less Martin 😉 After two attempts (7 and 15 years) I gave up the institution of marriage for life. The first nearly drove me into financial ruin, the second was so jealous that after every business trip I was subjected to the Spanish Inquisition, you can only stand that so long, last heard of with her boyfriend in USA. I divorced both. Lessons learned. Since 1995 I have a great partnership with my German girlfriend Gisela, who was also married once, to a latent alcoholic. We both agree; we don't need a piece of official stamped paper (much less a church paper) to show we love each other. We've been partners now for 23 years 😉 Cheers, Doug 😎 PS; "were" is correct. I have to admit that there was a transition period while working in Brazil that was very interesting 😉 This post expresses purely the poster's opinion based on his experience and in no way denigrates or derides the differing opinions / experiences of others who had more luck.

Yeah, might work with thin needles and tight stitches 😁😁😁 Quick blast of EzeKote an' there ya go 👍 Could also get the Better Half involved in the production line😉 Don't get ya needles in a twist,cheers, Doug 😎

Windows, stoopid question. by RNinMunich Fleet Admiral!   Posted: 6 days ago
Ahhh! MiniCraft, Good stuff. I have their 'Buffalo' drill (with chuck), miniature jig saw, and table circular saw. All driven off the same variable power supply. Can't get spares for the saw blades any more 😭😭 Bought the whole set about 40 years ago in a special offer from the AA (Automobile Association NOT what U lot are thinking!) . Drill been dismantled and cleaned / re-greased 4 or 5 times but still goin' strong 👍 Proxxon not cheap, but good, well made. My lathes, milling machine and grinder are all Proxxon. They just go an' go an' go. Cheers, Doug 😎

Crash Tender crew by RNinMunich Fleet Admiral!   Posted: 6 days ago
Aha! Similarity of names threw me off for a minute there! Should have known (slapped wrist)😲 Thinks; did I really want to know about the baby poo? 😡 In my experience phone cameras can be very fussy about light levels, esp for close ups. Comes from the tiny aperture I suppose. Cheers, Doug 😎

Crash Tender crew by RNinMunich Fleet Admiral!   Posted: 6 days ago
Hi Martin, coming on well. Thought you were going to use the Supermarine in the CT not Meteorites? No sweat; Meteorites (or Meteors?) are modified Targets / Torpedoes so I can make a conversion board for those as well (I think😉). One or two in your boat? Typical snag with phone photos; they don't like doing close ups 🤔 That's why I use my Sony Cyber Shot for the close ups I post. Tried the Samsung camera, fuzzy result - lens too small! Depth of field limited. Cheers, Doug 😎

Hi Braulio, Some masterful stuff there👍 and good clear photography 👍👍 Good to see the Atlantic Challenger. Many years ago a colleague and I did the COMMS system design for the original😊 Love the Minions and floating 'crapper', some imaginative folks about 😁 Cheers, Doug 😎

knitting pins by RNinMunich Fleet Admiral!   Posted: 6 days ago
Hi Mark, What do you use them for ?? Didn't know one could knit boats!! 😁😁 Do you just drop a stitch or two for scuppers and hawser holes etc ? Cheers, Doug 😎

Windows, stoopid question. by RNinMunich Fleet Admiral!   Posted: 6 days ago
Agree Martin, I thought you previously meant hassle with purchasing from Germany! Maybe the cutting takes two minutes but the setting up longer and at the end you've expended two or three not exactly cheap cutting discs🤔 Like Mike I also find the discs useful for accurate cuts in thin sheet material; mostly non ferrous metals and plastic. But not in hardened machine tool steel! Check the spindle threads on you 'Lidl' drills. You might find (like I did) that it's the same as the Proxxon so you can get a spare chuck from Proxxon to fit!😉 Did the same with my mini milling machine as it also came with a collet set. Have ordered from Tracy dies with slits and dimples 😊 Strangely on their site the die diameter wasn't given but they answered my mail query by return so I also ordered the appropriate die holder / wrench. Cheers, Doug 😎

Longer run time by RNinMunich Fleet Admiral!   Posted: 7 days ago
Hi, Lead acid doesn't like delivering the high currents brushless motors want. They are more suited to long term low currents. Go for a LiPo, 3 or 4S, something 7AH plus should keep you going for a while. Don't put batteries in parallel as one will inevitably try to charge the other, unless you have a hi power diode board in between them to prevent that. Cheers, Doug 😎

Windows, stoopid question. by RNinMunich Fleet Admiral!   Posted: 7 days ago
Good tip Mike 👍 thanks. What hassle Martin? Reichelt are on my side of the channel and the delivery is much cheaper😉 Could use an angle grinder for other jobs too, but not the huge things in most DIY stores. Will check what Reichelt has. As for Dremel; recently bought a set of their Speed-Clic cutting, sanding and polishing attachments. Amongst them were a couple of diamond tipped metal discs. Haven't tried 'em yet though. Anyway new proper cutting dies and a decent holder, + tail-stock die holder are on their way from Tracy. So I should be armed for the next task in this area - threading the 4 shafts on my Belfast 😊 Cheers, Doug 😎

Windows, stoopid question. by RNinMunich Fleet Admiral!   Posted: 7 days ago
Hi John, I wondered about cutting slits, BUT figured the steel would be very very hard and my Dremel cutters wouldn't manage it, (my other cutter is for bricks an' such), AND the damn things have no dimples, they are hex nut shape 😭 Figured I'd screw up my drills trying to put a dimple in it🤔 Recovery system On Hold till I get my cutter and PTB renovations 'on the road'. Cheers, Doug

Fitting Propshafts by RNinMunich Fleet Admiral!   Posted: 7 days ago
Was just pullin' your chain a little 😁 Sorry🤔 I'll do a quick measure up for the cutter 😉

Fitting Propshafts by RNinMunich Fleet Admiral!   Posted: 7 days ago
Interesting! Didn't know there is a market for such models 😁

Fitting Propshafts by RNinMunich Fleet Admiral!   Posted: 7 days ago
Yep, You just never know when STUFF will come in handy do you?😉

Fitting Propshafts by RNinMunich Fleet Admiral!   Posted: 8 days ago
Mornin Ed, 1 to 1. Basically cos that's what I've got in those big nylon cogs. Want to use the nylon ones cos they are wide, so more freedom of movement aligning them, and they should be quieter than metal gears. Think they came from old printers! Bought a batch of assorted cogs and pulleys at a flea market here years ago. Now they're coming in handy😊 Main purpose is to get the drive down to the propshaft which is mounted very low down in the hull as can be seen in the pics above 😲 Cheers, Doug 😎

JANE by RNinMunich Fleet Admiral!   Posted: 8 days ago
Nice 👍 Could she be a tick bow heavy? What was in the wrong channel ??? Cheers, Doug 😎
