1/2 boolits for lee hardness tester
I don't like how the lead boolits flat place made with a file so the hardness can be checked, it seems fuzzy, making it kind of hard to get a good reading. so I cut a square of alu thatI use to make gas checks with, I cut so it just fits inside the mold, I close the spru plate, make sure the edge is against the spru plate, close the mole, pour, 4 1/2 boolits, they a have nice smooth surface to test, it makes it easy or me to read the microscope. just thought I would toss this out there.
I do things a little different, Ed....
...no surprise there, I reckon. ;)
Ed,
Get you an old microscope. Then tape the Lee scope to it.
I use a very old Tasco and some new age rare earth magnets under the deck for the V-base that goes in the presses ram.
Ben sez pictures sure help. So here are some:

If I had a bit better camera you could see the scale in there. [smilie=b:
Also, I use a 1/4" die grinder with 100 grit disk on it. (I have a large air compressor and air piped around my shop)
I put my sample in a very small vise, and grind a nice flat slowly and gently.
Does two things for me...
Gives me fairly consistent flats.
And let's me take even slower passes to get fine hash marks.
Whatcha think?
