Well I just did one real slow, and the same thing, it's nanofused to the hole saw. The pilot hole is 1/4" and the arbor hole is 5/8, this thing is such a bear that now Im thinking maybe some 1/4" threaded rod stock with a 1/2" od nut on it and using the Python shaft puller on it. I tried a regular big drill bit but it tears up the acrylic, it seems they need to be specially modified for plastic and those do not come that large. I tried a forstner bit and it doesn't make a clean hole. David In a message dated 3/29/2008 8:27:44 A.M. Pacific Daylight Time, [EMAIL PROTECTED] writes:
Slow down the RPM of the drill! You are generating too mush friction heat which is causing the scrap to deform and fuse itself into the hole saw. You could also use a Forstner (spelling?) bit which just "shaves" the hole rather than cutting the diameter. Been there done that! **************Create a Home Theater Like the Pros.
