Been offering this for some time but finally have it listed to buy online.
We all know Metal or Copper laps can be contaminated or damaged or just get worn out - over 95% of these Laps can be made usually better than new with the high quality Diamond Lathe tools we use today.
We normally machine about 0.040" to 0.080" ( about 1-2 mm) to ensure any Diamond used in the past has been removed.
Its simple - $44 for one usable side of a 6" Lap and then $22 for each side after that so gather them up and save
Prices for 8" are just a bit more and are online. Reason for the higher first Lap is we need to change a fair bit on the Lathe to set up for Lap work after general Machining.
