So I have collected enough aluminum to build a surface grinder attachment for my 2x72. But as I was turning my disk brakes while doing a brake job, I thought.
Why cant I use a fly cutter on the mill to ensure a blade is perfectly flat?
Has anyone done this? As long as its not longer than my table, im not sure why it wouldnt work?

I have tried this. Mind you, I have a Sherline mini-mill, and it's not really cut out for heavy work, but it did work. It was nowhere nearly as effective as the surface grinder and took a lot more time. In general, a mill finish is not even close to a sanded finish in terms of smoothness. You can still see the rings created by the mill cutter. A surface grinder with a stiff wheel produces a faster and smoother finish. I typically surface grind to 220 grit.
The best use I have found for the mill & fly cutter surfacing trick is with handle scales. Get one side flat on the 6x48 sander and move to the mill to create a parallel face. I also have a steel surfacing plat and will glue a handle scale to it and run it through the surface grinder. Much faster than the fly cutter.
