Yes a copper pipe would be ok with me if I can find one. The old bush is fairly thick, perhaps I could bore the old bushing out and push a copper liner in.
The wrist pin has any where from 1/2 to one thou wear, measures 7/8 in and is very hard.
I took the old bushing out and set the rod on a granite plate. The rod little bore does not seem to line up to the big bore. I need to check that out. If babbit does in fact swell as it cools I could try filling the small end and then somehow drilling and reaming to align with the big end.
The small end bore is roughly tapered by about three to four thou . By design or just loose tolerances?
I jumped the gun on the bushing I made and did not discover the taper until too late.
The old bush is not tapered and appears to be soft steel with bronze or some fairly hard liner. Possibly I could bore it a little and pour babbit or tin solder and ream it.
Oh well, I will be thinking about it.
