Paul,

What type of varnish or shellac should I use on this? part is finished
except for trimming the outer ring off by hand and filling a few knot holes.

Larry

You can still buy shellac and shellac is the traditional stuff.
There may be something better out there since 1947 but I do not know
what that would be. Three coats of shellac are called out with fine sanding
between coats. Then waxing is called out.

That pattern looks wonderful Larry. I am sure a lot of people
will join me in thanking you for this wonderful effort.

You have done a great service to the cause of furthering rotary engines
in aircraft.

Paul,
Coat it with Epoxy, first coat diluted with Acetone.

Does it ball up on you?

I like the idea because it can add a lot of strength.
Especially if a layer of four ounce glass cloth is added. Four ounce, for those
of you that have not experienced it, is like thin silk.

I am inclined not to do it this go around as we want to try the pattern out
as soon as possible. Extra time and labor.

Paul,
I've had no problems with it 'balling-up' if it's completely gone off, it
sands very well indeed and the thin coat penetrates well into the timber.
I used it on my timber mould, as well. As a matter of fact I have used it on
everything timber as it protects it well.
I don't think I'd bother with the glass - too many bumps to go over. When I
did the final glass pattern, I used timber stiffeners (over the plain glass
bowl) to make it easier to make.
Use epoxy with glass beads to fill holes/ knots, with some flock for bigger
holes.
