Please don't try this at home kids.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.
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.Works for me.
