Sharpening End Mills on a Junked Disk Sander
vtsteam:
I decided to use some 1" square aluminum bar stock I had -- cutoffs I bought in a barrel at auction once, as end mill holders for the sharpener. I took one of the aluminum blocks and another strip of 1/8" by 1/2" steel, and positioned them to get the exact space needed from the one I just filed. I clamped the steel strip down with a welder's clamp. (first photo)
Then I removed the spacer block and spot welded the new strip in place:

Then I took three of the aluminum cutoffs and faced, drilled, and reamed 3/8", 1/2" and 3/4" to fit some end mills.
vtsteam:
It turned out that for shorter mills the slide can be on the close side of the sander's table slot:
And for longer mills, I can turn the slide around so it is on the other side of the sander's table slot. The 1-1/2 degree relief angle stays in the same orientation, either way. The blocks can be rotated 90 degrees and replaced in their slide to sharpen each of 2 or 4 flutes.

Not seeing amy pictures... :shrug:

Sorry Chris, looks like the problem is that the images are old http hosted, and some new browsers now insist that they be https. I guess I'll have to re-do all of the images to make them work. But they will no longer be in-line, which sucks.
This will take me a little while to do.
