Was about to scrap a part until I tried a different way to set my work offset

I was getting a weird .003 taper on a 4-inch aluminum block, so I touched off on the finished side of the part instead of the vise jaw. Has anyone else fixed a weird tolerance issue like that?

Oh man, that's a solid trick. I had a part that kept coming out with a weird lean, like one side was just a hair higher. Drove me nuts for a full shift. Finally just touched off on a known good surface from a previous op, and it cleaned right up. Sometimes you just have to work around the machine's little lies. What other weird fixes have you found?

Ever tried tramming your vise?

Tramming the vise is a whole project, grantp28. Last time I tried, I spent an hour with a dial indicator only to find my mill's table was the thing out of whack. Felt like tuning a carburetor on an engine with a bent crank. You get everything perfect in one spot, then it's off by three thou on the other side. Makes you want to just hit it with a dead blow hammer and call it good.
