Everytime I come on this thread it reminds me of how much of a hacksmith I am. I need to get better......

I lost some confidence in continuing this one because of the squish band being so uneven.
I ended up just widening the exhaust and cutting .010 of the base.
There's also a casting defect in the cylinder wall. 500i

Removed a little from the band and epoxied the intake. Still need to set it's fine intake numbers.

Was the squish band damaged in some way?

No, it just needs cut down, I didn't have the time last go around to cut it. Though after I did that 661 cylinder and got that saw back together I started taking apart the 500. So tomorrow evening I'll probably do that.

Edit: if you meant that 661 cylinder and not the 500, yes it did have some damage, it was a second hand cylinder with pinging at the top*

372xp big bore still need to do the uppers.

What are you folks using as a release agent to keep the inner form/barrier or piston from sticking to the epoxy
Just a thin wipe of oil, car wax, cooking spray, or....?
I'd like to fill the large gaps between the transfer caps (to cylinder cut out) of a redmax blower ebz8500, but of course I don't want to accidentally glue the caps to the cylinder.

I use metal foil tape on the inside of the bore

I use masking tape, then it will sit ever so slightly proud. Inside the cylinder, it can be easily removed with a slight use of a razor blade then some 220grit lightly applied the 220 won't harm the plating. (Unless you start using excessive force)

Squishband is cut on the 500! I dropped it .042 by the end of it.

Old piston with a light coat of grease.
