Ah, so true. Will know better once I get it cleaned up and the rest of the pistons out.
In the old days shops had a big bow device that held croakus cloth and was weighted. It was attached to a lathe head so the cloth could line up with various throws or mains. Then the crank was turned at slow speed with the polishing cloth bow pivoted down on a crank throw. A certain time limit was observed, and then moved to each throw, or main. Pretty low tech, but the polishing cloth really didn't remove any metal, just gave it a mirror surface.I finally got the block to the machine shop today. Good News, cylinders are straight and he recommended a hone and clean up. I need to find someone that can polish my crankshaft as he does not have that tooling. But, everything went better than I had hoped!
Wow glad you caught it in time.I finally got the block to the machine shop today. Good News, cyclinders are straight and he recommended a hone and clean up. I need to find someone that can polish my crankshaft as he does not have that tooling. But, everything went better than I had hoped!
My buddy Gary still uses that Machine.In the old days shops had a big bow device that held croakus cloth and was weighted.

Bet nobody uses that old setup anymore, just because it's not high tech now. The guy who built my 283 for my '55 gasser used this method back in 1970.
There ya go! Likely a true expert in his trade who knows how to use it too!When you find a 80 year old machinist still working with the right tools!
