Voltage increasing via regulator by EricMB Commander   Posted: 8 hours ago
Evening all, I have a voltage regulator I’d like to fit to my Southport tug (currently running on 7.2v Ni-MHs) in order to get it up to 12v. I’m after more speed/power and would particularly like the bow thruster running a bit faster than it does on 7.2v. So, the questions are, where to fit it in the wiring loom, and what will the effect be on the battery life? Advice please! Thank you in advance...

Old outboard motor... by Westquay Fleet Admiral!   Posted: 8 days ago
That's how the modern ones work, but I assume the flexi is stainless cable rather than a spring. I have one from Hobbyking for a fast little kneeler to 152VO rules, even though I'll never race it as all their events are in Germany and Holland and I don't have a Passport, but I do like the boats. I shall be off to try cutting this ancient one apart to repair the motor and wiring. I'd love one of those Keil Kraft Elmic Sprite outboards, but can't justify the cost. And any of the O&K scale working o/bs are gorgeous. Cheers, Martin

Nice work there Dave, is there a wiring schematic for this model.

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 1 month ago
Hi Pete, Welcome back👍 Yes, I did remove the moulded rungs. No chance of cramming the wiring in if you don't. I just twisted them out with a small pair of pliers and machined the rest out with a 3mm milling bit in my mini drill. I had hoped you would come to the 'cluttered' conclusion about the mast! Don't know of any standards for lamp spacing, never thought about. Spect there is, maybe Ed (figtree) knows, but he's having internet problems at the moment 🤔 Thanks re antenna cables. Not difficult with a couple of chunks of copper wire and the pin-drill. Some time I will also add the two small booms carrying a GPS antenna and an anemometer. Re anchors: all tugs I've ever seen have anchors. This is on my list of 'Missing details on the model'. It's quite a long list🤔 Pics attached showing the anchor in a recess on the stbd bow. BECC still exist but only seem to sell through agents/stockists now. Here the US/Canada stockists;- http://www.becc.co.uk/contents/en-uk/d47.html This probably your best bet http://www.loyalhannadockyard.com/ Some of the others have disappeared😲 Look forward to your winch sketch, cos I wanna build one too! Cheers, Doug 😎

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 1 month ago
Hey, Doug What you’ve done so far looks terrific. I noticed that you stayed with four lights on the mast itself. I take it you’ll also replace the two “dummy“ lights on the stub mast (behind the pilot house) with working ones? I considered the same thing but I like the look of all six lights on the “main” mast. Based on how things usually work out for me I’m still going to put a divider or barrier in the mast before I button it up. If there’s the slightest ghost of a chance of a short in the wiring it’ll happen to me. Five minutes’ work & a scrap of plastic will help me sleep better. Regarding the winch, it appears to be a very simple unit (see attached photos). The large bitt/towing hook unit in the photos hides some of the winch details, but it doesn’t look like a complicated unit to model. A few pieces of plastic sheet stock, some rounds & a few bits from the spares boxes is pretty much all it’ll take. I plan to attach the winch assembly to the Deckhouse; not to the deck. The base plate for the winch will need to be shaped to fit around the horn speaker grille holes in the deck but otherwise no problems. I already have a large roll of scale rope to wind around the drum. If anyone who reads this happens to have photos or a sketch of the winch in full view please post them if you’re willing. Thanks. Pete

Mornin' Pete (it is in Germany anyway!) I agree, there are lots of details and 'standard equipment' missing from the basic model. You can see the winch and Life Raft canister in one of the photos of the original I posted above. Re Mast wiring; don't fiddle about putting a divider in the mast. It'll just get in the way. Attached is a pic of my modified mast. I used a 0.5mm brass wire on the right-hand side for the earth return. Wire is better than rod cos it's flexible (can be pushed into the corner). I glued it in with gel Gluper Sue WHEN all connections were soldered and tested. The LEDs are standard domed lens types. I ground the tops flat and painted the tops with several coats of matt black until it was opaque. After testing I closed off the mast with some plasticard and fitted ladder rungs made of copper wire. I also added the missing antenna cables to the bottom of the VHF IMM antennas, 0.5mm brass wire. (Some time I'll also fit the missing GPS antenna and anemometer.) Then painted the mast matt black. I then turned my attention to the searchlight and red/green NAV lights. First I stripped the wheelhouse roof and painted it white as in the original. On my model it was grey🤔 Then I drilled out the searchlight to accept a 5mm Bright White LED. You won't have to do this cos you have a later version with lights, mine had none 😭 Then had to paint the searchlight with several coats of matt black. Otherwise it just glowed all round! Pics show construction stages and finished lighting effect. All wires inside the wheelhouse roof I super glued to the ceiling and ran them down inside the funnels (stacks to you guys across the pond!😉) ready for connection to a switch board in the hull. While I was at it I rubbed the false Southampton name off the cabin using a 1000 grit Tamiya sponge and am preparing inkjet printed decals with the correct Wyeforce name and logo. Have fun getting all lit up Pete,😁 Cheers, Doug 😎 PS Attached some pics showing the original 'Southampton' 😉 and making obvious what's missing on the model 🤔

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 1 month ago
Hi, Doug: I hope all is well. FYI, I’ve received all but one of my parts orders needed for the LED Mast Light project. The flat top LEDs arrived today & will be perfect for Nav lights. I don’t know if I mentioned this before, but a while ago I decided that instead of starting work right away it would be best to wait until everything I need for the project is on hand. While waiting for parts to arrive (& mysterious eye infections to clear up) I looked the boat’s Cabin & Pilot House over & made a list of details I want to add, changes or replace, not least of which is the conspicuous absence of a towing winch. Other things like adding a life raft canister, better looking life rings, fire extinguishers, etc. will come later, after completing the Mast LED Nav lights & wiring changes per your design. This brings me back around to a wiring question. Some time ago we discussed using a common ground bus inside the Mast & soldering each of the six “-“ leads to it rather than using six wires to do the same job. I plan to put a plastic divider piece up the middle of the Mast & run the six “+” LED wires on one side. The other side will have the bare ground bus onto which the “-“ leads of each LED will be soldered. The question is: what gauge should the bus be? I was thinking of using a length of brass rod but I don’t know what diameter to use. What do you think? Thanks, Pete

Still Stripping......With Care! by NPJ Fleet Admiral!   Posted: 1 month ago
No way through to the bow from inside as first compartment is completely blocked off. I am thinking some 'putty' then tissue and EsiKote or resin for the whole of that area both sides. As the clean off progresses, thinking about general layout of the 'bits' and wiring layout. NPJ

SLA Batteries! by RNinMunich Fleet Admiral!   Posted: 2 months ago
Ed, What you are writing makes no sense whatsoever!😲 Where are you measuring these voltage swings? PM or mail me a sketch of the set up and wiring in your boat with photos showing all power connections please. Are you sure the batts are in series? Something's very peculiar somewhere. SLAs only go reverse polarity, and then not much, when they have been deep discharged and then neglected for a while. But they NEVER recover and come back from that! Cheers, Doug 😎

Launch ELAINE, by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Colin, Any pics of the control gear? Ain't seen plaited wiring and plugs and sockets like that for decades, and then only when repairing someone's ancient radio or 'HiFi'🤓 Attached pic shows working principle of the Kitchen rudder. Primarily for steering it would seem, not sooo effective for reversing😲 Cheers, Doug 😎

So close just the superstructure to do.. Even put.a 60kg long tow winch in lop full rewiring and she pulls like a train

Martin's Taycol Conversion Boards by RNinMunich Fleet Admiral!   Posted: 2 months ago
Howdy Ed, Yep, will do. Have taken some pics along the way. Mast lights and searchlight are working. Red/Green Nav lights fitted (had to spray the roof the right colour first - white not grey!) but not wired up yet. About to do that now. After that the two aft facing Towing lights and deck flood lights. Also discovered that there should be two deck lights P&S of the main cabin😉 Will need the miniscule chip LEDs for those - Now, where did I put my microscope🤓🤔 In fact while researching I found there's a whole list of 'bits' missing. Not least the Life Raft, which should be behind the wheelhouse!!😲 (In God we trust - But just in case we want a Life Raft 😁) Have also started drafting new decals with the correct owner's logo and fonts. The wiring is only a lash up at the moment to check that everything works. As soon as I'm happy, with resistors an' all, I'll fit some mini connectors. More soon, (in a different thread cos this will bore the pants off Martin. A NO Lights Man!) That reminds me of a banner I once saw above the RAF Controllers at the London Air Traffic Control Centre. "RAF controllers do it in the dark" 😲😉 The civil side was brightly lit, other side of the wall the RAF guys had minimal desk lighting only. Cheers, Doug 😎

BRAVE BORDERER by RNinMunich Fleet Admiral!   Posted: 2 months ago
Hi Rowen, Interesting snag! Can you send me a wiring diagram please. Sounds like you might be getting some cross coupling of control pulse ripple through the battery wiring. Reminds me of similar problems on naval COMMS systems where we had to fit filters to all the power supplies to prevent cross coupling of sensitive info from 'Secure' to 'Plain' systems via the power leads! BTW: All brushless squeal and scream until the the pitch gets beyond human hearing frequency range 😉 Alternative: If you use two 3S LiPos, each of half the capacity of the original, you should get the same endurance with only a small weight penalty. This ain't curing the real problem though 😉 Cheers, Doug 😎

Old Futaba servo wiring... by Ianh Sub-Lieutenant   Posted: 2 months ago
Component Shop Do Servo Testers For Wiring I found this hope it helps

BTW John; Re LED testing: Yes I also use the 'diode' function of my multimeter to do a quick 'will it? won't it?' check. BUT that only tells me it works. With the tester I can determine the optimum current the LED needs, and thus the dropping resistor for any given supply voltage. Above a certain current, usually 20 to 30mA for the 3 and 5mm types, depending on type and colour, more current just produces heat instead of more brightness. Pic shows my tester, only few quid😊, see mA scale along the top! Runs off a 9V block. Cheers, Doug 😎
