If you don't want a cam then look at rotary valve and sleeve valve engines

they do have timing gears so kinda the same thing.

Won't the heat melt the epoxy? I know if I want to release anything from epoxy I heat it.

There are a lot of additional features that could be added and if I do the much modified version then a lot of those will be included. But this one will be quite close to the original as it would be a good beginner's first casting kit and as it does not come with barstock and fixings they won't feel obliged to go down the imperial/BA route.

The support leg under the end of the trunk guide would also be in keeping with what in the compound form is meant to represent a fairly large engine with rope grooved drum but then again so many other featured don't fit in with that size of engine for example it would not have had just two mounting points for the bed castings.

Thanks Mike. The plan is to try swaging first. If that doesn't work out then I'll fall back on epoxy.

Hi Ron,

Nicely proportioned sparkies. Do you intend to swage the body over the Corian insulator, or will you use epoxy?

I think I see where this is going (the spark plugs) but how do you keep the electrode from shorting/sparking against the housing?  Or does the Corian insulator neck down and fill all the way to the business end of the plug?
Hi Bent. Yes, that's correct. The Corian extends to the end of the threaded portion at the tip.

Turn Slim a loupe from brass, wire or twisty tie to hold it to his head! He might get annoyed if you run the wire through his ears though...
