Thread: An idea for a contact grinder.

You’re edge thickness should end up in the .005” area. I would think you could go slightly less than 2mm for ht.

You could set your drum sander up to do final sanding pretty easily I would think. A machinists vise with some flat stock and a series of spacers may work to keep from getting wavy. As you get close to final thickness free hand it to blend in anything around the shoulder since that may be a problem area with the swoop you’ll need to do to get the shoulder right.

I should be up and running in a month or two for heat treating so if you want to experiment with different thicknesses for heat treating we could probably get something figured out so you’re not spending all your time on finish grinding. Finish grinding is what took me the longest. There seems to generally be enough thickness to take care of any warping due to ht when grinding post ht. Smiling blades lend themselves to being slightly warped and still being able to maintain an even bevel and easy honing.
