Topic tags/keywords: safety side wheel grinding drill-driver question sharpening

Hello Jocks. Here is my deal. I bought this General Tool Grinding Attachment to sharpen my drill bits. $20.00 delivered. I have experimented with it on a few bits by side grinding on my bench grinder. It works super great, just take your time. Face grinding edge will give me a hollow grind. Yes I know, no side grinding. This is my thought. Why can’t I make a 6” grinding wheel out of plywood (I don’t trust MDF) and attach psa sandpaper to it and safely SIDE grind my bits on my bench grinder? My grinder is a dual wheel China Junk 6” at 3450 rpms. Maybe a solid oak or poplar wheel? I am also thinking of making a similar setup for my lathe and operating at a much lower speed. Hope to hear from someone. Thanx, Ripp

I would worry about getting it balanced, lahe sounds better , lower speed will lessen over heating

I don’t know about running a wood wheel at 3450 for any length of time regardless of wood type but if you do make one for your lathe use MDF and double it up.

P. Michael Henderson has a great tutorial on making a disc for
a lathe on the links above.

Have your say...
