Can you share> what you did to get the white stuff?> Heh, heh, heh. Boy that smoke system is alot of fun. Here is what I did: On one of the rear cylinder exhaust pipesyou weld a fitting about 3" down from the flange. (I used aSwagelok 1/4" female fitting) Drill two small (Number 40 orso) holes into the exhaust pipe inside that fitting you justwelded on. Run 1/4" copper or stainless tubing out from thatfitting about 8" long then connect to rubber hose (to reducevibration and prevent cracking your metal tubing or fiting)The run the hose into some 1/4" poly tubing- the black ortranslucent kind we use to run airspeed lines, etc. I think eventhe hardware stores carry something just like it. Run that poly tubing back to your rear cockpit however you like, and then go to Wal-Mart. In the garden dept. buy a 1/2 gallonbug sprayer/ pressure pump by hand type of deal for about 10 to $15. Unscrew the 'wand' or cut it, leaving some of thevinyl tubing intact. Use your choice of how to connect thebug sprayer outlet to your hose in the cockpit going to thesmoke injection port on your exhaust stack.Call around to local oil distributors and ask if they carryTexaco Canoupus Oil No. 14 I think it is. It used to becalled Corvus Oil. Don't quote me on the No. 14, but I canlook at my 5 gallon container at home to confirm that or not.Ask what's the minimum they'll sell you....usually 5 gallons.IT's not cheap. It's what the airshow boys use. I paid 30$for 5 gallons. (but got quite alot of smoke time with that)Anywho, fill your bug sprayer about 3/4 full, tighten thelid and pump up the pressure. Start your engine and let itwarm up. Run the engine up a little and press the bugsprayer's button to fill your line and start injecting oil intothe hot exhaust stack. Whala, insant IFR. Be careful testing this out- Make sure your fitting isn'tleaking or weld poor. The idea is to keep the oil insideso you don't create a fire hazard. If your holes are toobig you will go thru too much oil too quickly and most ofit will just make your gear and belly oily. In selecting a pump, see if you can try it out at the storefirst- It shouldn't take 100 pumps to get the pressure up- you want one that builds up pressure in fairly short order.I've tinkered with the idea of using a windshield washerpump and a motorcycle battery to pump the oil but just wanted to keep it simple. The bug sprayers don't last super long either with thatoil. If you purge the lines out with air when you are done(ie: turn the sprayer upside down and just pump air thruthe line) they last longer.

I'll be interested to see, but I'll bet money that a Model A stack, evenlengthened, is too short to produce proper smoke. More likely you'll coveryour airplane (and yourself) in half burned oil. Good luck, though. (takea fire extinguisher!)________________________________________________________________________________

Original Posted By: N321TX(at)wmconnect.com
Subject: Pietenpol-List: Smoke SystemThis smoke system seems like a lot of fun. How does it work? Is it easy to build and fit one? Or do you just buy one to bolt on?regards TugTug,My smoke system consists of an after-market windshield washer pump and tank, plumbing to each exhaust pipe, and wiring to the switch on the power lever. Iisolated / mounted the tank on the upper left motor mount tubing, with a couple layers of rubber strap. I routed the clear tubing to a Tee fitting securedin rubber, to the engine mount, then used 1/8" brass tubing to each of the fittings in the exhaust pipes. I laid out the route of the tubing, marked thepipes, and removed both exhaust pipes. I cut a 1/8" pipe coupler in half, radiused each half to the radius of the pipe, and oxy / accy welded them to theaft pipe of each side. After welded, I drilled one #60 hole through the exhaustpipes. I placed these holes toward the bottom edge of the fittings, theorizing that if oil would lay in there it would gum up. The switch is a pushon / push off button, that is mounted right to the throttle handle. This location allows me to work the smoke without taking my hand off the throttle. I originally thought it would only smoke good at full power, but came to find I don'tneed much over 1/4 throttle to Smoke 'Em Up !! I can smoke 'em while taxiing,without any problem !! My exhaust pipes point down and away from the fuselage, and even when all the oil doesn't vaporize, the fuselage hardly getsanything on it.I have a couple of squawks on the system, that I have taken care of. 1.) I mounted the tank at about the same level as the fittings on the exhaust pipes, and it always dribbles out the pipes, with a little bit of smokeas a result. Over a period of a couple of hours, it will drain the tank, but I usually 'Smoke em up' before that happens.2.) When I ran the tank empty, and refill it, the pump would cavitate because of the way the line ran from the bottom of the tank to the pump, and Iwould always have to prime the pump, by blowing in the top of the tank. I gotsome strange looks from folks, while I performed this operation !!3.) The tank was too small. It only was big enough to do about 3 smoke runs. I would like to put about a 5 gallon bucket up there on the firewall, butI don't have enough room !!4.) I had to remove the top cowling to re-fill the tank.I'm building a new tank out of fiberglass / West System resin, with a fill tube out to the right side of the cowling. I'll mount it lower on the firewall. This will take care of all the squawks.5.) I now have been using the new smoke tank, but I have a small leak in the tank. I used West Systems resin for the fiberglass tank, and evidently I didn't get the seam sealed up good enough. I've never had that problem when Iused polyester resin, but it kicks very quickly. The West System gives some time, but it is also quite a bit more expensive. After the warnings about thestuff catching on fire, I'll be repairing the tank before my next flight.Chuck G.________________________________________________________________________________
Subject: Pietenpol-List: Smoke SystemThis smoke system seems like a lot of fun. How does it work? Is it easy to build and fit one? Or do you just buy one to bolt on?regards TugTug,My smoke system consists of an after-market windshield washer pump and tank, plumbing to each exhaust pipe, and wiring to the switch on the power lever. Iisolated / mounted the tank on the upper left motor mount tubing, with a couple layers of rubber strap. I routed the clear tubing to a Tee fitting securedin rubber, to the engine mount, then used 1/8" brass tubing to each of the fittings in the exhaust pipes. I laid out the route of the tubing, marked thepipes, and removed both exhaust pipes. I cut a 1/8" pipe coupler in half, radiused each half to the radius of the pipe, and oxy / accy welded them to theaft pipe of each side. After welded, I drilled one #60 hole through the exhaustpipes. I placed these holes toward the bottom edge of the fittings, theorizing that if oil would lay in there it would gum up. The switch is a pushon / push off button, that is mounted right to the throttle handle. This location allows me to work the smoke without taking my hand off the throttle. I originally thought it would only smoke good at full power, but came to find I don'tneed much over 1/4 throttle to Smoke 'Em Up !! I can smoke 'em while taxiing,without any problem !! My exhaust pipes point down and away from the fuselage, and even when all the oil doesn't vaporize, the fuselage hardly getsanything on it.I have a couple of squawks on the system, that I have taken care of. 1.) I mounted the tank at about the same level as the fittings on the exhaust pipes, and it always dribbles out the pipes, with a little bit of smokeas a result. Over a period of a couple of hours, it will drain the tank, but I usually 'Smoke em up' before that happens.2.) When I ran the tank empty, and refill it, the pump would cavitate because of the way the line ran from the bottom of the tank to the pump, and Iwould always have to prime the pump, by blowing in the top of the tank. I gotsome strange looks from folks, while I performed this operation !!3.) The tank was too small. It only was big enough to do about 3 smoke runs. I would like to put about a 5 gallon bucket up there on the firewall, butI don't have enough room !!4.) I had to remove the top cowling to re-fill the tank.I'm building a new tank out of fiberglass / West System resin, with a fill tube out to the right side of the cowling. I'll mount it lower on the firewall. This will take care of all the squawks.5.) I now have been using the new smoke tank, but I have a small leak in the tank. I used West Systems resin for the fiberglass tank, and evidently I didn't get the seam sealed up good enough. I've never had that problem when Iused polyester resin, but it kicks very quickly. The West System gives some time, but it is also quite a bit more expensive. After the warnings about thestuff catching on fire, I'll be repairing the tank before my next flight.Chuck G.________________________________________________________________________________
