Think its a T3 or 4 its 500watt I think max collet 8mm, Stupid 42mm collar though so had to turn a 43 > 42mm adapter!!.

At full speed its toooo loud!!! And at lower RPM's looses to much torque.

As for the DVD laser diodes, Yeah cost about £30 aswell so bargain!

I will start a new thread with as much detail as I can offer if there is any one wanting to try it.
