Ordered and received today this attachment for my 2X72 grinder.
It is a 9 inch flat grinder, which can be used vertically and horizontally. Excellent tool for flat grinding blades,scales, and a bunch of other tasks.
As you see, the grinder turns by using a 2X72 belt, and can be operated at different speeds through my variable speed controller. Also works forward/reverse.
Test drove it on a few heat treated Magnacut blades/scales I presently got on the go.
Should have bought one of these long time ago! Does a great job and will save on a whole lot of hand sanding.
Not really a "hunting knife" topic, but thought I'd share...
