Rocker oiling

Yeah, I don't think I'd want to have a true press fit on a 10-12" piece of soft copper tube that has to be hammered all the way in. It would collapse before you got an inch or two in, even with a mirror finish on the bore of the hole. Even if it was line on line it would be a ***** because a drilled or even reamed hole is anything but smooth.

Plus the tubing is nominal. I was getting the tubing from somewhere back in the early 2000’s and it was .6250-.6265 IIRC.

When I finally ran out of that I bought some from McMaster-Carr and it was .6238-.6251 or close to that.

The reamer that came in the Chrysler kit I bought in 1988 to do a block had a reamer that was .624 so you ended up with a .001ish press fit.

I used it once. I loaned it out and the dude broke it.

And he never replaced it either.
