I have spent a lot of time in the last several months researching the next generation of Twistor diamond lap. As some may have read in this forum, this prepolishing lap was an Adamas/Gearloose collaboration that Gearloose could not continue in manufacture due to the abrasive swarf the process generated. For those who liked the Twistor, I have good news for you.
The new Twistor, which I call Twistor2, has double the diamond layer thickness of the original Twistor, greater resin bond hardness than the original, and double the diamond concentration.
The color of the bond will be a light yellow brown on a dynamically balanced, 1 cm. thick aluminum alloy baseplate. The lap will be 20 cm. in diameter with a 7 cm. wide by 3 mm. thick diamond layer.
This lap produces a prepolish, but the slightly coarser micron size and higher diamond concentration produces significant material removal so prepolishing large tables takes place relatively fast, you can finish cut girdles without as many lap changes, and use it without concern of "pressing too hard" which is a caution issued for a resin bond lap made by another company. This is a water drip lap that is compatible with Adamas water soluble lubricant.
This lap will be available very soon, but I can answer questions right now.

Good news Tom. I look forward to it. These are nice laps for stones that could otherwise get cutting oil impregnated in them.
