Side Valve i.c. engine from Bar stock
Brian Rupnow:
After letting the Loctite set up for a couple of hours on the pressed in valve cages (.0015" interference fit) I drilled the connecting holes thru from the carburetor and exhaust mounting surface to the center of the valve cages. Now my engine will be able to breath in and breath out-----------

:clap: :clap: Looking better as every post you put up appears. I'm really looking forward to seeing you fire her up for the first time......OZ.
awemawson:
I thought that loctite required a small clearance fit not an interference fit?
Manxmodder:
Andrew, that depends on the surface finish on the component faces treated with loctite.
Years back when I was frequently involved in fitting press fit cylinder liners it was recommended practice to produce a honed crosshatch finish inside the cylinder block or barrel that the liner was being pressed into and use a low viscosity loctite retainer compound.
The loctite film occupied the small troughs in the honed surface......OZ.
Brian Rupnow:
Sometime to day I hope to visit one of my suppliers and pick up some suitable head gasket material and some high temp sealing compound for the two bolts that have their heads exposed in the combustion chamber. I don't want to hone/lap the cylinder until after I have permanently locked the cast iron cylinder and the valve body (which I have been mistakenly been referring too as the "combustion chamber") together. In the meantime, I have just rattled off a quick detail of the valve. I see some people make valves out of stainless steel and other exotic materials, however I have always used just plain old garden variety cold rolled steel and never has a valve fail.
