learning has occurred today. I try to push the limits on edge geometry in order to see how thin I can bring an edge on a given steel. For years I took S90V to ~.007-.010 BTE post HT. Decided to try taking a large radius hollow grind S90V blade to less than .005. I did it, but the edge stability was terrible (hitting bamboo and press cutting hard wood dowel.), so backed it off to .007. I think with S90V at 61-62 HRC, .007 is as thin as I am willing to go.
 
Needed a hollowgrind hand sanding jig and did not want to order one. Had a piece of thick aluminum laying around so I have 10”, 14”, and FFG all in one. (Don't know how durable it will be but simple and quick enough to remake if need be).

way bigger then anything i've attempted before. 5160, almost done on a full flat grind my poor belts, i over did the forge thick and grind thin on this one, think i ground off damn near a pound of steel. my poor belts...

I'm in a similar position with a massive kukri haha!
 
It's amazing how much steel comes off wide blades in a flat grind!! I did a 12" chopper from 2" wide 8670 a few years ago, forged it wider and some of the bevels in and it still lost a lot of weight while grinding it!

Navman, sounds like a reason to upgrade and get a mill! LOL.

I’ve always admired @Lorien framed hidden tangs so here’s another I just finished in cruwear. A little finicky but I like the process

I got this blank cut out, profiled, drilled, stamped, and jimped today in about 2.5 hours using my crappy 1x30, files, and other small tools.

This will be my third knife... :cool:

Finally got a chance to play with the SG-1 for the TW90. Made a bunch of thicker steel thinner.

You can also turn steel into an unguided hypersonic missile if you’re not careful. At least that’s what I’ve heard… I’ve also heard that they can be hard to find after they clear the tree line on the other side of the yard. I certainly wouldn’t do such a thing but, you know how you occasionally hear things…

Always a concern...much like with a:

Buffer
Grinder
Drill press
Mill
Lathe
....

Putting a small "stop" of metal on the magnetic chuck helps prevent turning a blank into a missile
 
Agree on the metal stops, at least for regular flat grinding. I generally taper tangs down to just about nothing so in that case stops can cause them to come out sideways. So, I aim the SGA out the big door into the wild blue yonder to keep anything from bouncing off of something or someone if a blade comes off. It’s easy for me to know everything is clear in front of it that way. Fortunately I don’t have to make the same mistake more than 3 or 4 times to learn from it. Now I remember to make a few passes with the machine off any time I change something. Obviously the thinner the grind, the less the magnets are able to hold. Just going from a slightly worn belt to a new one of the same grit can liberate one if you don’t adjust the table correctly. Certainly a learning curve with them. I haven’t had any issues since the first few weeks of using mine.

The buffer is more dangerous than just about anything else in the shop. I normally attach my blades to a wooden handle with a couple of screws when I’m buffing so I can keep a solid two hand grip.
