Jemma 7

[T.L.A.R. eng]

Has anyone built the Jemma 7 from SIC volume #72-76?

I am wondering if the prints are buildable, and are there any mistakes to watch for?

A search on the net brings up very little on this little radial.

Any comments?

T.L.A.R. eng,

I am building this engine right now and the prints are usable but there are several missing dimensions on the drawings. I have had to redraw some of the parts in AutoCad to come up with my own dimensions which hasn't been a real big deal so far. I have the crankcase, cam case, intake manifold, distributor gear/carb mounting housing, and the front covers finished. Getting ready to start on either the cylinders and pistons or the crankshaft and con rods.

It is going to be a long build but I'm in no hurry.

Hope this helps.

Thanks for the reply 3jaw,
I noticed some of the missing dimensions but figured they would be obvious when I got to that point.
I know what you mean by a long build, but I like most of the features of this engine.
Thanks for the heads up.
