Got clamps and the CVS extra long heating pad (per
@Goldfish's rec) earlier this week, and 43mm ceramic blanks from
@BR Pro Poker today--got 38 blanks (35¢ each), because that's how many I could get before shipping jumps from $6 to $10, so I can flatten 36 chips (18 chips + 19 blanks per clamp).
Don't have the ribbed racks, so I just hand placed the blanks and chips while holding the bar clamp vertically. The chips may not be dead even center on the blanks but I made sure none of them were too close to the edges. Set the heating pad to 160F and covered the clamps and chips. Will check and tighten in 20-30m, maybe flip the clamps over (even though I have the heating pad covering the top too).
