Looking good Does the Snow engine use rollers to follow the cam? If it has flat followers the cam flanks could do with a radius.
I think the inner two studs will be a bit of a problem to attach a nut to them.Can you glue a nut to one side of the stud and use it as a bolt. I do not know if this makes sense to you.Vince
Nice work as usual Achim.I see that you are making good use of your cutting machine for the gaskets. I recently purchased a Silhouette Cameo machine and have been learning how to run it. My first attempt at cutting gaskets was not completely successful. I was cutting a rubber reinforced fiber material about .017" thick; no matter what I did it just wouldn't cut clear through. I think the rubber in the material allows it to push away from the knife. I was able to get usable gaskets by finishing them with a sharp X-acto knife. Maybe I need to start looking for some different gasket material.Can you remove the cylinder assembly from the base to install the exhaust valve cages?Dave
Some times cutting rubber can be helped by putting it in the freezer for a while, with thin stuff like that, probably best to put the cutting board in the freezer too. Rubber would be best cut with a wad punch.Ian S C
