We rented the Isky O-ring tool and did some cutting for o-rings today, but didn't get very far. We finished cutting on the #1 cylinder and tried to install the copper wire in the groove, but it wouldn't stay in the groove.
We miked a section of it and found it was only .038", not really an interference fit in that groove.
So, I came home and ordered some .041" stainless steel wire that I hope will fit better, and stay in the groove when I hammer it in.
Here are a couple of pictures.
The dummy piston with the bolt in the center is a piece I had made in an effort to catch the filings and keep them from getting places they shouldn't be (like, between the piston crown and skirt.) It is perfectly round, is tapered, and 1" think, and sized to have only about .002" clearance between it and the cylinder wall. The bolt in the middle is threaded into the dummy piston about half and inch, and is only there to provide a handle for removal. Vaseline will form a meniscus between the sides of dummy piston top and the cylinder wall and trap the filings. At least, that's the plan... I hope it works...
