Smoke generator by jbkiwi Commander   Posted: 15 days ago
Have just made a prototype of a fan forced smoker which seems to be working well (despite breaking the heater coil by moving it while hot, - had it apart, broke wire, screw and washer repair, not quite as hot) I bought a couple of Heng Long smokers (for R/C tanks or cars) to play with, for $10 NZ each(or 5.3 Euros to you Northerners give or take a yen) from Bangood and just bought another from Ebay. There seem to be 2 different models, as one has a long coil with a lamp wick draped over it, which is sitting in the oil reservoir, the other has a small coil inside a piece of heat resistant woven tubing (as you might find insulating toaster/heater wiring etc) which acts as a wick and that also sits in cotton wool in the reservoir, (this seems to be the better of the two) Tip - don't fill the tank right up, only enough to soak the cotton, element should be just out of the oil. The wick loads the element. The better model seems to have a black top to the tank (also maybe either brown or black tank) and the other has a brown top and dirty brown tank. As with most of this stuff you won't know till you get it what it's going to be. What I did was remove the tank and cut off the pump tube just in front of the screw lugs (see black line in photo) then fitted the tank, and a 40x40x10 5v ESC fan (voltage controlled by a UBEC set to 5v on the jumpers) into a plastic electronics utility box from Jaycar (our local electronics and hobby store). I made up a double JST lead for the 2s 1800Mah Lipo and fired it up (using baby oil). It's pretty much silent and smokes well once it gets warmed up, ( starts smoking in about 5 seconds) You could control it (on/off volume) by either a remote on/off switch or perhaps a small cheap 10A brushed ESC. I would leave the fan running and control the element to avoid burning the element. The original pump tank inlet hole seems ok as is (approx 1.5mm) but you could enlarge it very slightly to get a better flow if you could find a better oil. At the electronics store they have proper smoke machine oil for $20 NZ per litre so I may have a look at that. The reason I went for the fan idea was that I found in std pump form, if I immersed a tube from the tank in water, it sucked water back into the tank. I was hoping it would pump smoke out of my HSL exhausts at water level alongside the cooling water but it would need a very light non return valve to do this. The fan seems to pump the smoke through 2mm ID silicone tube ok, so tubing of similar ID to the OD of the tank outlets should work well. These pumps in original form work pretty well for the price, and are cheap enough to keep a few for spare elements, the only thing is they are a bit noisy but in an 'engine sounding' way, (might add to the effect on a tug or work-boat though) What you have left after this mod is a very handy little geared motor with an eccentric output wheel which could be used for winches, radar and whirly bits of any description (see pic of motor leftover and original) To avoid burnout, these should be run on no more than a 2s (around 7.5v-(suggest 8v max with fan running) The other tank is going to work a lot better than this one but I'm not making a tug, just want a bit of exhaust smoke on start-up etc to go with the 2 sound units. Very cheap to make (around $25 NZ with pump, box, fan and UBEC all through Ebay, Aliexpress and Bangood (and local electronics store) If you wanted to run an ESC to control the smoke and you have no channels left to control it proportionally, you can always try using a second receiver bound to your TX, (if your TX will allow it,) power it and a brushed ESC (wired to the element) as normal and use the throttle channel to plug in your smoke control. This should work if you want more smoke as you accelerate or if you are using only 1 stick on a 2 stick TX you could use your 'elevator' stick pushed up (or a toggle switch if available) to start/stop the smoke (through the brushed ESC setup) . This setup weighs 100g (10g more than std) The quest for lots of smoke continues Will try to upload vid later and update progress.

Hum, Now What! by figtree7nts Fleet Admiral!   Posted: 1 month ago
Captain's Log: Continued! I have found where the leak is coming from! It's coming from above the shaft as it exits the hull! I'm not sure why it's leaking. The area is tricky to get to. As it's deep in the hull! An hard to get to. Since the hull is made of plastic. Am thinking of making a flange plate! And gluing it to the aft end of the hull On the outside of the hull! But, of course need to see where the leak. Is coming from the outside...…. I have already looked into getting a water pump. Also a water detection circuit to activate the pump!

Oh, NO Water Everywhere! by figtree7nts Fleet Admiral!   Posted: 1 month ago
Captain's Log: Ok, I like to float Tug Brooklyn! Last night I did this. I filled the tub with water. Then placed Tug Brooklyn. I left it alone for about half an hour. When I came back. I started looking at her. She looked different in some way. I hadn't realized she was taking on water. anyway I looked at her water line. And her water line was below the water! I then took her superstructure. Off of her when I looked inside. I was shocked to find. She had taken on more than 12 ounces of water! I then started to panic! I went and got my syringe. Which I had purchased just in case water ever got into her. And started pumping out all the water she had in her! I'm not sure where she's leaking from! Or why she is leaking! There's only one opening in the Hull. And that's where the shaft comes out of! Going to have to do another float test. to see where the water is coming in from! I'm glad I discovered this before next boating season!

Hi Gary yes 1946 Nov. but young at heart. Rick

steam water pump by GaryLCoupland Chief Petty Officer   Posted: 1 month ago
Good Morning Rick, well it is here in the U/K. out of curiosity, I had a look at your profile as I imagined you were young and just starting off with steam, at least I got the second bit right and discovered you were of 1947 vintage, easy to figure out as I am from 1946. That was a bit of a shock to the system, anyway I thought I would share with you the fact the TVR steam engines are manufactured in the US of A, across the border by Graham Industries, almost on your door-step so to speak. Regards, Gary.

Thanks Gary will look at it in the morning . Rick

Hi Rick, I am afraid it is me yet again, who said you can't teach an old dog new tricks. Despite the odds, I have managed to upload my steam engine video on to YouTube and on here, check out videos on this website and you will find it, it's a bit on the long side at twenty-five minutes, but you have to admit it runs like a Swiss watch and is very efficient in not wasting any steam. Regards, Gary.

Thanks Gary I will look at the steam engine. Rick

Hi Rick, if you google TVR 1ABB steam engine, you will find a really neat and very good value for money steam engine. I'm afraid this is not cheap and around the £250 mark, mind it does have ball race bearings on the crankshaft. This comes as a kit of parts and you have to build it from scratch. when you have completed this task you will have a really good knowledge of exactly how a double acting slide valve engine works while putting this together, you can save up for a boiler to go with it, the instructions for building are very good almost idiot proof they must be as I have built several. Beautiful engine and powerful it will easily power a hull of one-meter length. Something to think about and Christmas is coming.

Thanks Gary for the picture I only hope when I get the steam plant I understand enough to have a plumbers nightmare. Rick

steam water pump by GaryLCoupland Chief Petty Officer   Posted: 2 months ago
Hi Rick, I thought you might be interested in this, it looks a bit like a plumbers nightmare, but despite that, a beautiful engine a twin cylinder TVR / USA slide valve 1/2" bore, and incredibly efficient runs on only 30 PSI steam pressure. The boiler is 3 1/2" x 6" and will run for almost 30 minutes with no water pump, carrying water adds a lot more weight.

I like that idea thanks Gary

steam water pump by GaryLCoupland Chief Petty Officer   Posted: 2 months ago
You don't need to buy a water tank, simply build one into your hull using plywood and fibre-glass, the favourite is the sharp end simply fit a wooden bulk-head and cover it in fibre-glass.

sent you a photo of a mechanical boiler feed pump connected to an oscillating V4 engine. get on eBay and type in Microcosm steam engines. If you use a decent size boiler for your steam engine you should get 20 to 30 minutes run-time. Let me know how you get on. Regards.

Thanks Gary I have looked at their site and yes they have a pump I'm looking at I e-mailed them to find out if they do boiler water tank . Rick
