Rebuild starts by RNinMunich Fleet Admiral!   Posted: 1 month ago
Mornin Peter, That's probably your best bet👍 I find it convenient to use my cheaper single action airbrush with a 0.8 nozzle / needle setup for larger stuff like hulls, and keep the more sophisticated dual action set with a 0.5 (very occasionally 0.3) for detail work or the smaller 1/350 ships. For the latter rattle cans are of course totally useless, but the scale is just to big for decent brush painting (for me anyway😲) Saves having to fiddle about changing the setup so often😉 Happy spraying, cheers, Doug 😎

Hi Doug. Iwata do not do a 0.8mm nozzle for my air brush. I will look into whether my other cheap one can be altered.😊

Launch ELAINE, by Colin H. Fleet Admiral!   Posted: 2 months ago
Well today the radio specialist guys checked out the reciever for me, apparently it would need a new capacitor, a 90 volt and a 2 volt supply. Not really possible in such a small boat. So I've decided to use it for my vintage displays. The boat itself will be renovated and fitted with an electric motor, possibly a 600 as I have a couple in the spares box. Still looking for a way to remove the kitchen nozzle system. The motors that operate it are working so hopefully should be controllable by modern rc gear. Might need Dougs help designing a system I can build. BTW the Hull and cabins and deck is constructed from 1/4 Inc ply. Bit heavy but good and solid except for some of the frames are very soft and crumbly. Will start a resurrection blog soon. Cheers Colin.

Well Martin, sorry to put adampner on the proceedings but she does have throttle control, but the return spring broke during the test. Have removed all except the nozzle control as I haven't figured out how to remove it without damage yet.

BTW, that prop shaft looks like it hasn't been sealed in it's hole in the keel. Wonderful though the kitchen nozzle is, It must cause huge drag. Cheers, Martin

Launch ELAINE, by Westquay Fleet Admiral!   Posted: 2 months ago
Fantastic stuff, Colin. If you can get that ancient engine to run on diesel from your car plus Methanol, you could get that kitchen nozzle going! Where did you just get some methanol from? I'd say the engine is something like an old ED Competition Special or similar with a very home made water jacket and even more home made exhaust wrapper, requiring tubes to be added to the 2 stubs and led to the stern or either side. Doug's yer man for anything lecktrickal. Is there actually anything of the original RC in there apart from that superb kitchen nozzle affair, which deserves to be preserved all on it's own. Control will have been vestigial at best as the engine has no throttle and the nozzle arrangement will not have had any level of proportionality to it. It will, at best, have been push the button and see where the boat ended up, knowing it could, at a a pinch, be brought back to where it started. At one time all RC was like that. My own REP set was left,centre, right, centre, etc. A wonderful throwback that must be preserved. I wish my local junk shops had stuff like that! Cheers, Martin

Launch ELAINE, by Colin H. Fleet Admiral!   Posted: 2 months ago
Thanks Doug, I sort of gathered this principle but had no idea how to control it. There are two motors connected via reduction gears and levers to move the two parts into the various nozzle shapes for the thrust and the whole thing rotates via one of the motors also with reduction gearbox. The pictures are the best I could do with it still in the boat as I have not figured out how to remove it without damage yet.

So far, only checked the engine, it ran using a little diesel from my car mixed with a few drips of methanol. Throttle spring broke and the flames from the exhaust were about 4 inches long but it sounds healthy enough. As for the radio gear I'm afraid I don't have a clue. Have managed to get the rudder nozzle gear to move using 6 volt battery, but all the connecting wires are missing. Lots of wood inside that needs attention, seems a bit too soft. Cheers Colin.

Mahogany in Scale by Colin H. Fleet Admiral!   Posted: 2 months ago
Well Martin, its their loss. I try to make everything except the electrics. I suppose I'm lucky in being a retired prototype engineer, with my own machines and space to work. These days I am restoring more than building, I find it more challenging. Spotted a vintage boat in antique shop today, it had diesel marine power and valve and relay control system with a strange adjustable korts nozzle arrangement. I am trying to get the wife to let me buy it. Cheers Colin.

Painting. by RNinMunich Fleet Admiral!   Posted: 3 months ago
Evenin' Neville, For a first attempt spraying that's damn good👍 I prefer to use a 0.8mm nozzle for 'big' areas such as hulls. 0.5 for the 'fine' stuff, e.. cabins and fittings, which I still need to practice! Will need it when I come to the cammo pattern for PT109. Practice makes perfect they say! Basic rules (THEY also say😁) are- Paint consistency should remind you of milk (no cream!), Don't get to close, Don't move too slow! Keep up the good work👍 Cheers, Doug 😎

Painting. by MouldBuilder Captain   Posted: 3 months ago
Hi Doug. Thanks. You are right about the first aid. Clumsy. Good that my wife is a nurse me thinks.😆 No. This is my first attempt at spraying anything like this. That is why I ask a lot of questions. I try to build up knowledge and the courage to have a go. I was lucky this time, so far anyway. It is not perfect by any stretch, nothing like yours, but I am relatively happy with it. Takes quite a while with a 0.5mm nozzle but once you get going, you soon learn that the paint does not go on too thick so the chances of it running are less, I think.

Emerald - "Round the Word" ocean racing yacht. by East-RN Sub-Lieutenant   Posted: 3 months ago
Auto Bailout Modification. 1. I drilled small holes in the lower corners of the cockpit wells, opposite each other. These were then connected together with some small brass tube. This was to allow the water to flow from the front cockpit to the rear cockpit. (See pictures 1 and 2). 2. Two more holes were drilled in the rear cockpit, in the outer corners further aft. these were fitted with brass tube stubs. These were to take the plastic tube, which runs to the nozzles fitted into the hull (see picture 3 and 4). 3. To ensure the water would not flow into the boat, while stationary, the tubes were run through small eyelets on the under side of the deck(see picture 5). 4. Small holes were drilled in the hull and brass tubes were cut and bent, so that they would pass down through the hole in the hull, and lay flush against the hull, with the opening facing aft(see picture 6 and 9). 5. On the outer hull, the tube is built up, and covered in a cone shape, so the tube opening is the widest part of the cone and flush( see picture 7 & 8). 6. When the tubes are fitted to the stubs on the aft cockpit, and the cockpit secured in the yacht, the bale out is complete. Principle: While the boat is still and on an even keel, the cockpit floor is above the waterline, the tubes raise up to the deck level which prevents the water from flowing up and into the yacht. When the yacht starts to move under sail, the water flowing over the outlet nozzle is forced out by the cone, and creates a small vacuum at the nozzle opening, which draws any water in the cockpit through the tube and out through the nozzle. During a gust or strong winds, the yacht will heel over more. This will bring all the cockpit water to the lower side bailout tube, and be drawn out by the vacuum. When the yacht slows, and becomes even keeled, the cockpit will have been emptied. During heavy gusts, I found that the yacht will heel excessively, and if the waves are high enough, the cockpit will take some water over the deck. This is why I fitted the bailout device. So after a long sail in heavy weather, a long cruise back to shore on a broad reach and more even keel, will ensure the cockpit is dry. Happy Cruising

Spektrum, new, useless... by RNinMunich Fleet Admiral!   Posted: 3 months ago
Yep, otherwise known as a 'Jockstrap' 😲 SC is too sweet for me, and prefer V&T to G&T. Can't get the smell of gin passed me schnozzle 😡 Pims #1 is also good. Tally Ho chaps! Temp here has collapsed 10°C again, cloudy and rainy. Expecting 37°C again at end of the week though, Phew!! GWS to Chris, cheers, Doug

Booster nozzle by reilly4 Admiral   Posted: 4 months ago
My suggestion would be to contact the Kehrer shop directly. They are most likely to answer any of your queries. Looking at the booster nozzle it looks like a circular section squeezed into a smaller square with the cross fins to straighten out the jet thrust.
