Engine vacuum

I'm going to do the engine vacuum ... but there is so little information about it, everyone can give me drawings, information.., I can do the cylinder, piston aluminum ??

What do you mean by "the engine vacuum", do you mean that you are going to build a "flame licker". If so the best metal would be cast iron in a stainless steel cylinder.

I'M SORRY !! YES ..I'm going to do the flame licker !! I want to make the cylinder and piston aluminum so tractable and research .. then will do better ..I can do the cylinder, piston aluminum ?? there is so little information about it, everyone can give me drawings, information..you can guide me somethings ....

Aluminium has a number of difficulties, first is the high coefficient of friction. Next it has a high rate of expansion, so to fit a hot cylinder, it needs to be made with a large clearance when it is cold.
Yes it's nice and easy to machine, and easy to obtain, but the cast iron in a stainless cylinder is more correct engineering.

Hi Ian. I too am going to make a flame flicker and was thinking of using aluminium as the cylinder, however, I see this should not be the case.
Can you use steel for the cylinder and use aluminium for the piston? It is hard to get cast iron here in Atherton or anywhere close here.

Atherton, Australia? Yes I understand that, know a bloke in Cairnes with similar problems, got to send over seas for bits, quicker than from down south.
You might be better off with brass if you can get it. Aluminium doesn't work the best rubbing against anything, bit of a bl**%$ nuisance.

Thanks for that Ian. Yep just out of Cairns but a long way from NZ.
Brass is a product that I still can get. Thanks for putting me onto the right stuff as I have had a lot of problems using aluminium.

I have built one of Jan's flame lickers, I haven't got it going yet, might have to try again.

One inch bore. I took all measurements from the scale on the drawing.
