Sblack You are so right! A bit it over a year after scraping in the cross-slide I tore it down to make some improvements for better oil penetration into the dovetails and hand flake it.
While I had it apart I put it on the surface plate. It was out and I had to re-scrape that and the compound.
I'm certain that everything was within a tenth or less before.
The carriage bottom was done while I was feeling crappy and I really made a poor job of it. Also, that was before working over the mill so I had no way to machine it, which every part of that machine really should have been. Had to remove a lot of material by hand.
After catching up on a few other projects I'll tear it down and machine the bottom of the carriage and scrape it again.
Will probably need to make a couple tools so I don't screw it up this time.
The tools I'm using are very crude and ugly, only partly finished, cheap carbide on crappy home made handles without proper wood ends.
Hey, I kept thinking I'd just do one more part and maybe never scrape again. Dumb Huh!
I started out doing the compound with a parting tool and just tape on the end I held.
The lathe carriage travels well now and is rigid enough that I've parted aluminum1.5 inches DOC and mild steel, 1018, 1 inch DOC without any chatter or problems.
It just cut through making nice curls. Couldn't part at all before scraping. Prior to scraping the lathe and mill, oil would just poor through the dovetails.
Now Ive had to put oil grooves in them and provide a path for air to escape or the oil can would explode from the pressure of trying to pump oil under the lathe carriage.
petertha I really must apologize to everyone for not posting more of my progress and HuHum, "minor" errors.
Now that I'm feeling better I'll run down my pictures and share more.
