Any update on the Continental piston?

Still stuck harder than a Stock Brokers heart.

Ive been busy, so havnt had much of a chance to screw with it.

Ill pull the rod caps next, and try to get the crank out from under
the pistons, then pull the engine and take it back to the guy I bought
it from and let him rebuild it.

As a last resort, Ill put a cold chisel to the offending piston, then
bash out the bits

Ill post when I have an update

Having taken apart many engines that have sat for 70 years or longer, I have
had good success with Coca-Cola. Sometimes it takes a week or even a month
with Knight type sleeve valve engines that have iron pistons installed with
..0015 clearance.

Its got a half can of Kroil sitting in it, with periodic bashings
using a 1x1 and a hammer, around the edges of the piston.

Ditto the Kroil and some Marvel Mystery Oil my Hercules 6 in the
Lincoln 350. I try the starter on occasion, to no avail. I should put
the beast back up on Craigslist today. I'll never get around to fixing
it.

I got anything you want in trade?

Might be fun having two gas welders sitting in pieces in my back yard.

Is it worth putting the head back on or drilling/tapping to suit and fitting a
bit of ground/milled/shaped/scraped heavy plate. then completely filling the
cylinder with oil and screwing a threaded rod into the plug hole?... you'll
get the most force for the least localised stress by hydraulicking the piston
rings loose.

IIRC, a while back Gunner said the stuck piston is at BDC and
the engine would have to be detached from the generator before
the oil pan can be taken off and the rod pulled, and unhooking
the engine isn't easy.

I about drove myself nuts onetime trying to hammer out a piston from a RD350
engine.

Took a lot of hammering to figure out that the cylinders block was floating
on the crankcase.

Once I bolted it back down with spacers instead of the head, I was able to
maul the pistons out.

I still like my hydraulic idea.
