I have 400 and 600 grit metal sandpaper and a flat surface. Can you describe the process of sanding shims?

Thank you!

get some 220 and get back to me. ;D

seriously...those grits are unnecessarily fine for the job.

Get a diamond stone.  After you get back to Nate, he'll tell you to use a figure 8 motion to avoid creating an uneven surface, and turn the shim occasionally.  You'll have to take a few measurements to get an idea of how fast you're removing material.

actually I don't use a figure 8.

I push straight ahead and rotate the shim 900 every other push.

I find it to cut faster and still maintain a flat level surface...but I use 220 paper.

Well.  I do the same thing, but I was always told to do the figure 8 thing, so....    

The stone is way easier to use than paper, and they last forever.

I never prescribed to the do as I say theory.

I want everyone to have the opportunity to do it wrong like me. ;D

Never thought of using my diamond stone, that's a great idea.  It's much smaller and easy to handle than my 12" square marble tile and sand paper.  Almost any pattern should work if you rotate the shim often and don't press on one side of it excessively.

we were taught the figure 8 for not flattening round things, like valve balls

I do the push and rotate for anything flat, like shims

I'm curious, has anyone noticed any difference in the actual size when measuring a now "hot" freshly sanded shim?

I don't move fast enough to get them hot. ;D

Seriously, I don't think it's an issue.

If you're concerned you could always use some oil on the wet/dry as a lube.

It would get difficult to hold on to the things though.

I usually use WD-40 on wet/dry, no problem holding on to the shims.
