Looking for someone who has LOTS of experience flattening leaded Paulson chips (3 Viewers)

Another tactic- I’ve gotten my best results with clamping and then putting it in the sun for a few hours. But it’s slow and weather dependent.
 
I'm also interested in this service, though I cannot afford $500/rack. If the PMer wants more work please PM me too!
 
Flattening chips:
Get a 4 inch C clamp and 10-2 inch washers.
Alternate chips and washers inside the clamp.
Tighten enough to keep all chips in clamp without falling out. Snug, not much more.
Heat oven to 140-150 degrees.
Place chips in oven for 15 minutes.
Remove, tighten clamp until snug again and cool for 5 minutes.
Place back in oven for another 15 minutes
Remove and let cool.
:)

Please don't try this at home kids.
 
Works for me.
C clamps don't apply even pressure across the full chip surface. 150F is too hot for Paulsons, you can squish them at that temp. And I've never seen a washer that was perfectly flat and prefectly smooth on both sides.

I would stick with the parallel wood clamps with ceramic blanks between chips at around 125F for 30 min if you want good consistent results that won't damage your chips.

Ok. I agree with that, no Lakeshores. I have done this many times with mint starburst chips and look like all the rest. No flattening or other damage has ever happened.
