Same Shindaiwa 577 is still on the bench. I only get a little time to work on it between my real jobs, but here goes tonight's thrilling session:
After I put the crank halves back together, I masked off a few bits, and sprayed on a few light coats of rattle can paint...Ever press in a Shindaiwa piston pin? They are tight. So under the suggestion of Four Paws, I made a wrist pin press from a 3" clamp. I knocked the end off the clamp, swaged on a couple flat 5mm washers, and turned a spacer pin on the little Pratt & Whitney lathe.
Said pin, now pressed in, with a new Shindaiwa piston kit - so all new OEM piston, wrist pin, circlips, wrist pin bearing, thrust washers and rings. All brandy spankin' new. Piston ring compressor? My fingers. They've always worked good enough. I deleted the base gasket, and wish I'd spent the time to take a little off the bottom of the jug or the crankcase base, but hey, it's just a work saw - my work saw. Hondabond HT seals the base of the jug now. Then, I reinstalled the exhaust studs with some locktite.
I did a muffler mod, dusted the can in the blaster, and sprayed on a new coat of VHT paint. And on went the muffler. These old 577's have a pretty decent muffler as it is, but there's always room for improvement.
Time for more mechanic's fuel....

Its OK im sure that pic would be much better as a vid fire it up and let it leave 6
Its OK. It could be much better if it was running and leaving you in the dust anyone agree that we need a vid?

The good thing about it all is that it will never end as far as the saw thing is concerned. I like it that way.

Still can't find the info I'm looking for as far as the actual squish band demensions... Bell's book is mostly bike/cart info. I'm guessing a 4-5mm wide band? Not sure how thick... Seeing as it's a flat piston I'm guessing no need to angle it toward the combustion chamber center(?).... I'm going with a hemispherical chamber with the plug in the center. Now the area between the center chamber and band should be tapered in towards the center I imagin right??? Some many questions
