Default RE: Home made smoke for 4-stroke

I got those parts from a hardware store here. They have just about anything you can think of. But one thing is those brass fittings are pretty heavy. But that is all I knew to use for my idea.

I drilled a hole in and smaller than the brass fittings. Then I just used epoxy around the threads and screwed it in place. Its hard as a rock now and don't seem like it would move. I have no clue how much pressure it can take max. Like I said I just made this up out of my head. I been pumping 30-35 lbs in that small tank. I have a gauge on my pump that I use. I found anything lower than that did not work to well.

I would like to make another tank and put the fittings used from ROBART on it. Also use high pressure lines with it. Then all I would need is one tap in my tank instead of 2. I could use some T's and then the valve and should be good to go. I also looked at the air tanks they have but there kind of big to squeeze in my plane.

I tried it out again today and found I had to much oil flowing. It was spitting out before it had time to heat up. I messed around with it to find a good middle point where it would smoke finally. For some reason I don't think the oil is heating up enough the way I have it now. It goes into muffler near the header and does work. But it is not as thick of smoke as I would like.

My engine is still new so it does idle to smooth yet. It starts to chop pop and some times backfire and reverse rotation. Today I was running my smoke when the engine slowed down and backfired. It started running backward and I never seen so much smoke come out. I mean it was really thick and looked awesome. Wish I could get it to flow like that out of the muffler. This time I was flowing out of my cowling....oops

I know it would probably be easier to go out and buy a smoke set. The way I am doing it now is aggravating but I figure it is not going to work perfect the first time I try it. It is going to take a few tries before it right if possible. I just thought it would be cool to be able to make up something cheap that would work. I like to mess around and this is giving me something to try out for fun.

I will post updates as I try different set ups on what works and does not work.
