I have managed to find a very cost-effective and simple way to index or re-index a part that you need to put back onto the table for further cutting.
This Red Dot Laser Pointer fits perfectly into a Razorweld Retaining Cup.
The Laser has two adjustments to center the laser.
All you have to do is push the Laser snugly into a spare Retaining Cup. (It fits perfectly)
Place the retaining cup into the torch holder and gently tighten the screws so that it holds it semi-tight but you can still spin the retaining cup.
Spin the retaining cup a few times while adjusting the laser until the red dot remains in one spot.
