I googled "drill hole saw in acrylic" and got this http://www.thebestcasescenario.com/forum/archive/index.php/t-1886 .html They suggest drilling halfway through and then flipping the sheet over. If you do your own search you might come up with something better. Let us know what finally works. Good luck! /Ed On Sat, 29 Mar 2008 13:30:33 EDT, [EMAIL PROTECTED] said:
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. [1]Watch the video on AOL Home.
