A few questions about lapping

post #1 of 10
Thread Starter 
Ok! I found some 400, 800 and 2000 grit sandpaper down in the basement, so I'm gonna test-lap a spare heatsink of mine!

Now, would this work? If I stapled the sandpaper to a 2x4, and lapped it that way, or is it better to use a piece of glass or something?

The flatter the material you use as a base for the sandpaper, the better.

Yes use glass, a peice of wood will not be true flat. I use an old door off a toaster oven, it is nice heavy glass with rounded edges.

I used a picture frame. Thicker glass is better. Or a mirror.

The issue there is, if you're applying that much force, you're likely to whet it down uneven. You have to let the weight of the lappee do the work. Check out my sig thread for the "skating" notion...

The lappee... is that me or the heatsink?
