Are the hole patterns and sizes available for the front of the spindle holder and laser (7w)?

Looking to make a very rigid laser bracket for mounting my 7w jtech head to the front of the spindle clamp. Tried measuring the holes and machining a bracket a couple times, but I just can’t get the pattern right to where its nice and snug. Does anyone have these measurements?

Sorry if this is a repeat question, i did try searching first and couldn’t find anything.


I just finished making an alignment-camera system that mounts to those holes, basically copying @TMToronto’s design. And very carefully measured the hole pattern so that I could choose compatible shaft holders.

Unlike most everything else on the machine, the laser-mounting hole pattern is imperial: 1.5” wide x 1” high on center. But the holes are tapped M5-0.8.

Thanks for responding! Those were the exact dimensions I used. I must have had a burr or something because i just reamed the holes out and deburred the edges and it fit better.

The laser head still has me confused though. The hole pattern dims don’t seem to land on a relatively simple value for me with both metric and imperial.
