Hi all,

I'm just starting to experiment with razor repair and creating new blades out of a 3 foot length of O1 tool steel I came across.

I only have a small 1x42 grinder and am hoping to get some better belts next week, but the contact wheel isn't impressive compared to those big belt grinders, and I have only tried hollowing the steel with my regular 8" bench grinder so far.

Has anyone tried the Norton white or blue grinding wheels that are reputed to run cooler? I was burning my fingertips (and work hardening the steel) on the grey wheel, and am thinking of trying the Norton. It's under $60 from Lee Valley (Canada) and hopefully will keep me from having to find any new equipment.

Thanks for any input,
Atchbo
