Re: MORE SMOKER STUFF 2

Re - Nope sorry JB🤔 dat's nix! Hence my comment elsewhere about scaling water Doug,(surface tension etc in miniature applications) Wonder if a surfactant introduced before the outlet might make a difference ? So many different exhaust methods in full sized boats, eg, vert dry stack with water side exit, (tugs, fishing boats etc) dry exhaust with water side or transom exit, wet exhaust side or transom, wet exhaust using waterlock system etc. they all act differently at exit, so you sort of have to pick 1 and try to reproduce it. A standard wet exhaust and a waterlock look totally different when they exit for example. Main thing is, we are getting some good ideas and feedback going, and I'm sure we'll see more "Smoke on the water, (fire in the sky)😊 in future. Who's going to be first to come up with black (nature friendly) smoke???? JB

Re: SEAPLANE TENDER TANK TEST 2

Re -Hi Guys, I'm back from the dinner date Hi Doug, the water lock s are usually completely hollow and valveless, and they are really simple (like me) As I mentioned, they simply fill up to a volume that resists the exhaust pressure which then builds up and pushes the excess out (they are always mostly full and always below the motor) only takes a few seconds to cycle at idle (depending on motor and type). Vid of one type working. JB

Re: SEAPLANE TENDER TANK TEST 2

Hi Guys, I'm back from the dinner date - keep the row down please I can't hear myself type!! "That's unless you have one of these nifty water lock s" One lives and learns JB 👍 The sounds super! OK, then set about building one. I guess it has some kind of flap valve inside? Sounds much easier to add water to smoke than smoke to water, or does it just sound so? Rather U than me Gunga Din. Oh!And BTW don't forget to add "Smoke on the Water" to your sound system - REAL LOUD 😁 I unshipped the water pump and pick-up from my Sea Scout (had used it for a steerable monitor experiment) now I'm tempted to put it back 😉 Happy head scratching JB 🤞 Cheers, Doug 😎

Re: SEAPLANE TENDER TANK TEST 2

Re - But that's just the exhaust, as I believe it should be That's unless you have one of these nifty water lock s Doug. Had one on the MkIII Zody motor in my 20 footer and they work really well. Exhaust comes from the manifold, cooling water introduced and then goes into the where it fills up and 'farts' out some of the water continuously. The water cools the exhaust and quietens it through the water chamber in the . You can tell if a boat has one (most do now days) by the burble burble pfupss sound from the exhaust (critics can invent their own sound description😊) You'd think they would melt being plastic, but that's how well they work!

Martin Westquay's Piper Cub ;-)

Found a locally and have fitted it. Put a carb full of fuel down its little gob , flicked it and Gor Blimey it ran for 5 seconds at least. Hasn't turned in donkey's years! So IC it is. Just started covering it in Solartex. An ancient roll I've had for years too. Bought originally to cover the cockpit area on my model of Miss Britain III, so almost none missing from the roll. Had trouble with wrinkles, but then found I was using the iron too cool. Turned it up and last night it all went well. Martin

Martin Westquay's Piper Cub ;-)

I confess I am in 2 minds over this. Having an OS 10 is ideal, but then it doesn't have a , so I'll have to make one, a bit of a faff. But then, I have fuel, somewhere a glow stik and I think my son even has my old starter for one of his boats. I love the smell and so does my wife so that's no problem. The lack of mess? Well it's only a wipe down with a rag when you're done. Starting frustration and dead sticks...yes, that's certainly a consideration. Our club is still more IC than electric, so loads of help if needed with recalcitrant engines. I recently re-bearinged an HB 25 and they got that running well on a test stand. Really, it's only the hassle that may yet put me off the OS installation. that and the fact that I've now glued up the firewall where the hole goes for the electric! Although that, of course, is for a big old 550, not a comparatively small brushless. Of course, then there's the expense. I don't have a big brushless (well I do, but that's in an outboard motor speedboat), I'd need a new ESC and I don't have a suitable battery. Biggest I have is a 2200 3S. Ah, just re-read and seen that's the battery you mention for the Cub. Martin

Re: Mermaid sport fisherman

I made a mod to my motor using an OS 45FSR bolted to the side of the leg and making a blanking plate for the std exhaust. This made it a lot quieter as you can imagine (the original was pretty loud,- old American std)
