Getting Close by carpemoment Chief Petty Officer   Posted: 9 days ago
I've been trying different configurations for controlling the sails. Finally settled on the winch circular method and managed to get it installed and calibrated. My tether broke the other day. Fortunately, a kayaker came along and graciously retrieved her for me. So I decided it was time to go ahead and add a motor. The drag of the tether was affecting my ability to get control of her. After a few failed attempts, I was able to come up with a configuration that works. Probably way overpowered but I had a spare motor from a defunk helicopter sitting around. AND finally, the beauty of her markings are back. I found a source for new labels (much easier to apply than the original ones that were water based).

Davits and falls by Gdaynorm Captain   Posted: 12 days ago
Dreadnought had two boats on Davits,slung each side of the funnel, and actually directly above the midship main armament gun barrels. I would assume the davits were able to tilt outwards to allow the boats to be lowered directly outboard. Would anyone know what sort of winches the falls would have been paid out with, or were they simp[y lowered by hand? As far as I can make out the rest of here boats were accessed by the crane on the mainmast.

RC Mixer by sam Petty Officer   Posted: 12 days ago
Hi, I'm doing some (a lot) of research before embarking on a Bristol Pilot build. My attention has now turned to controlling the twin fore sails. A helpful guy at my club mentioned using a 'mixer'. Anyone who has controlled two foresails and/or a genoa on a racing yacht may have some ideas here - any welcome. But my initial question is about terminology. Reading my Futaba handbook - a truly excellent translation 😡- I find two terms under the mixer section - 'OFS' and 'VR' - any idea what they mean? For interest, the problem is that the front sail overlaps the rear 'foresail' so we can not simply attach a sheet to the front sail to drag it to a 'tight' position as this may tangle with the rear foresail. The second problem is that if the foresail is out to the port, the drum winch must turn anticlockwise to haul it in, whereas when it is to starboard the winch must turn clockwise. I do love these problems, but desperately need help. If its only someone telling me not to be stupid and just lket the foresail hang loose - I'm not racing afterall👍 Sam

Carina by Hellmut1956 Sub-Lieutenant   Posted: 16 days ago
Trying to learn to use this forum properly I am publishing a video that shows an experiment I did to find out how fast the stepper motor could turn. I am using in my model of the sailboat Carina 2 stepper motors like the one shown in the video to work as a winch to control the position of the sails in a system solution where I am realizing this my own way to implement the sheets as shown on the original sailboat Endeavour. This requires my sheet control system to control the length of the sheet of the mainsail i.e. over a range of 8.3 meters. This requires the drum which is turned by the stepper motor to make 21 full turns. Details will be published in my report from scratch of building my Carina.

Gypsy Sloop Jr. by hammer Fleet Admiral!   Posted: 1 month ago
Go with swing arm servos for sail control, less trouble with the lines than winch. If room is a problem one can be used to control jibs & main. but separate controls are obviously best.

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 3 months ago
Hi, Doug. I’ve attached a zoomed-in photo of the “Anchor Enclosure” that’s built into the starboard bow bulwark of the Wyeforce. There’s an anchor in the box but I can’t tell for sure what kind it is. Maybe a navy-type with the fluke & bill pointed inward toward the deck? A better photo is needed to be sure, so I’ll keep looking. The enclosure itself would be simple to build & fit to the hull. I remember seeing a photo of the boat’s foredeck area that showed what may have been a hawse pipe running inboard from behind anchor enclosure & down through the deck, presumably to a winch belowdecks? Does that make sense? Pete

sound generators by Rookysailor Commander   Posted: 3 months ago
If you want a selection of various engine sounds, plus extra sounds i.e. klaxon,seagulls,winch sounds etc, the best one for the money is by Action electronics👍, part of Component shop. http://www.action-electronics.co.uk/engines.html Peter😉

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 3 months ago
Hey, Doug. Thanks for the photo link; I grabbed them for my reference archive. The winch can be seen again in one view; I think I have plenty of information now to extract measurements & sketch a fair representation. Thanks again. Pete

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 3 months ago
Doug: I feel like a dunce for not noticing that anchor before. It sticks out like a sore thumb if you know where to look. That’s another thing that I’m surprised hobby engine didn’t add to the boat. I guess in the long run it was easier for moldmaking purposes to omit that particular detail. That’s another thing, however, that wouldn’t be all that hard to scratchbuild. All that’s needed is to cut an opening in the bulwark & build a sheet styrene box for the housing. It’s not exactly a high priority item, but I think it would go a long way toward adding realism. So far none of the photos of the Wyforce I’ve seen show what the anchor enclosure looks like on the inside of the bulwark. Then again maybe some of them did & I missed that, too. I assume there’s an anchor winch, possibly below deck near the chain locker. I expect there’s a “drop/raise” button inside the pilot house. I’ll browse for a photo of the anchor & post it if I succeed. Thanks

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 3 months 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: 3 months ago
Hello, Doug: Out of curiosity, did you remove the molded-on plastic ladder rungs from inside of the mast to gain more space for wires? Seeing your finished mast has shown me that it’s best to keep the original nav light locations. Having all 6 lights on the main mast will make it look too cluttered. With all of the lights switched on it’ll look like a light saber is jutting out of the pilot house roof. Do you know if there are standards governing the horizontal spacing of navigation lights? There should be, otherwise I’d think the lights could tend to overlap & look like one big light, especially in fog. BTW, the cables you added to the mast antennas look great. The smooth curve of the cables & the weather boots at the antenna connections add a lot of realism. Well done!👍🏻 Speaking of details, do you know if tugboats carry anchors? If so, what type? As far as I know the US Coast Guard requires every powered vessel to have at least one anchor. I see no reason why tugboats would be exempt from this rule. I’m glad you mentioned using a Tamiya sanding sponge as a means of removing the factory-applied lettering. There’s a model railroad technique I’ve used successfully where an ordinary pencil eraser & window cleaner are used to remove lettering. I’m sure it would work on my boat but I might not live long enough to get it finished. Shortly after I got the boat I ordered a cloth American flag & scale Plimsoll markings from BECC. Sadly BECC has gone out of business. Another good supplier goes around the bowl & down the hole. Sad. Regarding the winch again, your comments tell me that I may have misled you into thinking that my boat has a winch. It doesn’t, but I did say I’m planning to scratchbuild one. In fact, I’m going to sketch one out right after I post this message. Thanks, Pete

LED Tug Mast Navigation Lights by RNinMunich Fleet Admiral!   Posted: 3 months ago
Hi Pete, Thanks 😊 Yep, I decided to stick with 4 lights cos tha's all I see on the original 'WYEFORCE'. Yep again! I do intend to modify the two lights on the stub mast; 1 yellow 'Towing' and 1 white 'Stern'. I will also fit a wheelhouse light. Decided to do it 'fluorescent' style by fitting 2 white 3mm LEDs in the ends of a long block of 5mm perspex. After that the 2 work-deck floodlights, lower cabin lights and 2 deck lamps 1 each side of the main cabin. I'll probably link the cabin and deck lights so that they all come on together. Now pondering how to build a miniature working diesel genny to power them all😁 Good luck with your divider! You will have more wires to squash in than I did so I doubt there's room. Have fun trying. I separated the wires quite easily by keeping all the negative legs of the LEDs (that's the leg going to the larger electrode in the diode) on one side and soldering them to the brass wire negative rail first. Then I took colour coded thin 'hook-up' wire to each LED in turn; working from the top down. Cut the LED leg to 1/4", stripped the hook-up wire back 1/4", twisted the wire strands together and tinned it. Tin the LED leg as well and bend it 90° down the mast. Then it's easy to solder the wire cleanly to the LED keeping it well away from any other wires. When all was connected, and tested OK, I stuck the wires down with thick gel super glue so they can't wander about. To fit the LEDs to the mast, I removed the brackets; removed the dummy lights with a razor saw, filed the mounting flat and drilled holes for the LED legs in them, using a 0.75mm drill bit in a pin chuck, and glued the LEDs on with gluper sue. Then I bent the leads 90° back towards the mast and drilled 0.75mm holes horizontally into the mast so I could literally 'plug' the lamp bracket complete with LED straight in and glue it down. Painted matt black the leads become invisible, as in 3rd pic above😉 Winch: at least your version of the model seems to HAVE a winch! Or where did those two pics come from? Mine ain't got nuffink, just a big 'ole at the back of the cabin😭 All the best, Doug 😎

LED Tug Mast Navigation Lights by pittsfieldpete Lieutenant   Posted: 3 months 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
