toolpost bolt force can warp compound

What I learned tonight--Scraping in a small lathe compound is a lot different than a milling machine knee. They move more.

Captain Obvious reporting for duty--!
It won't matter how well the compound is fit unless the toolpost is fit to the compound. Scrape in the top of the compound in the tee slot area, , and the base of the toolpost, and secure the toolpost to the compound. Then put it on the surface plate.

Since I had already scraped the compound, there was a ready made reference for how much change putting the toolpost on would make- I looked at it and thought, ya know, that toolpost could put a lot of movement into that little thing- put on the toolpost, and reblued on the plate and it was back to touching opposite corners.
Then I scraped the toolpost bottom, and the top of the tee slot area, put the toolpost back on, and the compound was back to almost flat.
It's getting there...:D
