Inlet or exhaust?

[JasonBModerator @jasonb]

And also does it need fabricating or will it be cut from the solid?

David, you need to tell us more.

 

What kind of I/C ? – diesel, glow, petrol, single or multi cylinder, size and anticipated use.

Nice one Rob but will it stand the heat.

 

David I have made manifolds/small silencers for two stroke glow engines (which have a very hot exhaust) to 61 size. They were made from ally and held together with a two pack epoxy type product called JB Weld. The early silencers were held together with a long central screw as well but the later ones were just JB Weld’ed with only one screw holding the silencer to the manifold. Virtually all were for aircraft – no failures experienced flying them regularly and in competition.

 

Here are a couple of before and after pics of a manifold made for an HP61 marine engine which is JB Weld’ed to the engine exhaust

 

 

 

Hope this helps give you some idea – any thing else just ask.

 

 

regards – Ramon

I’m worried about the head warping there, Rob.

 

At least you can slice a bit off to get it straight again
