help diagnose my scratch lines from a kmg ?

Probably a combination of both, but 1/8" thick steel will definitely flex way too much with appropriate pressure for hand sanding. I'd go up to 1/2".

thank you javand.

You might try going to the 80 grit sooner than you usually do on the grinder.

No belt machine grinds a flat surface, put the bevels
on a disc machine and you'll see this in seconds.

I ground this one on a 2x72 with a jig. I grind up to about 1200 grit (Norax U264 X16). I am in the process of building a disc grinder though.

Try some 3/8" thick paper micarta for a sanding "stick". Just buy a pair of 1.5" wide by 3/8" scales of some since black paper micarta it's dirt cheap and not as expensive as g10 or a nasty to work with.

That's what I've been using and it works great. I cut through one of the scalse lengthwise to make a piece about 1" wide. Then you can keep the other half inch or so for times you want something narrower to sand with. You also have the other full 1.5" wide scale for when you need/want something wider, and you can also very easily put different sized radii on the different edges for getting into tight area like plunges that might have different sized radii on different knives etc.

Even if you don't go this route, I'd say just pick up a pair of black paper micarta scales the next time you order more supplies anyway, that way you can make any size or shape sanding "block" you want, such as shaping a piece into sorta like a half round file for sanding curved areas, or an acute triangle shape to help get into and sand any file work on a spine (if you ever do file work) etc. etc... It's just a good solid cheap material to have around that can be used for all sorts of things, just use your imagination. :thumbup:
