Help - New grinder chips glass?

Post by Randy Sheeha » Sat, 12 Oct 1996 04:00:00



Hi,

        I just bought an Inland Proshaper. It has a 1" grinder bit and 5"
disk for bevels.

        I started working with some glass that I have ground successfully
in the past on a different grinder. This is the only glass I've tried so
far. I'm pretty sure that I set the grinder up properly (although I have
to say, the "users manual" was pretty sketchy!!). Seemed like I had good
water flow, etc, maybe even a little too much.

        The problem I'm having is that around the top edges of the glass
where I'm grinding, chips are coming off. Not huge chips, but I certainly
couldn't foil it, even if I wanted to! Am I doing something wrong??    

Thanks in advance for any help!

Randy

My first guess is that with a new grinder wheel, it has much more abrasive
action than the old grinder that you were using, and you're applying too
much pressure.  On a new grinder bit/wheel, I find that you need a VERY
light touch.

HiRandy,
I agree with Sam. Most chipping when grinding comes from either course
grit and or too much pressure.
