I used the white aluminum oxide wheels for years, still do in the cabinet shop, BUT after watching Toms video it dawned on me, Im grinding HSS not carbon steel in the machine shop a bit of heat doesn't matter, someone gifted me some 7 inch Norton grey hard stones, I switched to them, work way better, easy to hold a sharp edge on the stone to thin the web on a drill, and easier to keep the face flat.

I'm not trying to be rude but let's talk more in depth about tool grinding elsewhere and try to keep this to the item being created with the tools
I didn't get anything done last night unfortunately, work got in the way and we had a game night with some friends over. My fiancee leaves for a trip to Washington Friday morning so I will have ample time this weekend to play on the lathe in the garage.

Got the barrel looking like a Mk2 Mod 1 barrel today and parted off. I thought about making it look like it had a breech plug without actually making a breech plug, until I realized that i had turned the OD down too far well past the end of the barrel. Oh well, get to learn how to do inside and outside threads.
The knurling tool got cocked to one side so the knurling got a little ugly, perks of learning how to use my equipment 
The next step is to do some electro-etching so that it looks cool and then it will grace my desk. I plan on making several more. At least one of which will be donated to the EOD Memorial Auction.

Good luck with that one. These threads often drift away from the original theme, but that's how everyone learns. You just have to drag it back on course every now and then.
I'll start a new thread on grinding wheel selection under General Metalworking Discussion.

Snail....
I think your doing great, the best way to learn is to make mistakes.
could you please explain a little more on what this thing does in its working life..
Anthony.

It's used to shoot a 1"Dx3"L slug propelled by an electrically initiated .50 BMG cartridge through pretty much anything you can put in it's way. We use it to disarm tons of fuzes from hand grenades to 2,000 lb bombs. Of course, there are other options as well. Propelling water and steel shot or even just using the air pressure. The applications are basically limited by the user's creativity.
Mostly, it's just a REALLY old tool that is symbolic of our career field.
