2" x 72" Reeder grinder with a 2 HP motor and a VFD. It's a big step up from the 1" x 30" Harbor Freight grinder I've been using. Going make momma a new paring knife. ;)

Nice. Damn son, you have more "ramset" loads than a Home Depot. I probably have half as much myself though.
Wow, and industrial grade meat slicer. Makes me want a baloney sandwich.

Not a slicer. A sander. Although with a 36 grit belt on it you could make ground meat out of your hands a fingers if you aren't careful.

I have two sanders. One is a hand held Black and Decker oscillating sander. It doesn't actually seem to sand anything, but it makes workmanlike buzzing sound. The other is a belt sander that I needed to shape the corners on some cabinet tops I made. I have also used it for needs I don't experience often. A stationary sander seems rather specialized. What are you using it for?

Grinding steel. The plan is to make knives.
Everybody gets knives for Christmas next year.

Knives out!
I got a new toy too.
I can't share what it is or used for here.
But it does have a nice blue marble design
My grinder is up and running. Getting it running was the easy part. The hard part was reorganizing the garage so I'd have a good place to run it.

I wish my kitchen was as clean as your garage.

lol. If you had spent Friday night and all day Saturday, Sunday, and Monday cleaning and organizing your kitchen like I did my garage I'm sure it would be.
So I got the forge fired up and started 6 knives today. The 3 on the right have been heat treated.

Got a small wheel attachment so I can get into those inside corners easier.

Got eight knives shaped and quenched this weekend. They are in the toaster now for the first of a couple of tempering cycles.

I am jealous. always had an interest in knives as a hobby. studied what I could. probably watched more than half the knife making videos on youtube... but I am a long ways from having my own shop to play around in.
I didn't make a description to remember what any of these things are, but they are all related to metal forging for knives or melting metal for jewelry

apparently I missed my list specific to knives. The jay fisher page is probably the most complete information about heat treatment anywhere on the internet ( nice long read that includes some new and more expensive toys)

Thanks for all the links. As far as Jay goes, he practices metallurgy at a level unobtainable by most hobbyists. The equipment required to do that kind of work puts it into "I won the lottery" range for me.
I looked at the heat treat page but haven't read the whole thing. While it looks like it could be very informative it seems to lack some very basic things that would be very useful like tables of heat treat temperature and times for different steels.
be nice to have a heat treatment table with all the info in one place. So far I only find heat treatment info by looking at seller's data sheets
Well poop. It's a long weekend, and I had plans to work on knives all weekend, but my cheap Chinese VFD blew a transistor a little while ago so there will be no grinding until I get a new one. I think I'll go ahead and bite the bullet and buy a KBAC-27D.
The offending transistor.

There was a swordsmith in Yokosuka that I used to watch when I had the time. There was a line outside his forge on a side street. If you crossed that line without permission his helpers would shoo you away. I'd been warned about that and maintained a respectful distance. I visited once a week for about a year before he waved me and offered me a blade to inspect. I bowed and took the blade, then I moved to a rack of bladed and compared it next to another one. (I had seen him taking extraordinary care with that one.) I didn't judge but my eyes lingered on the good one for a few minutes. When I turned around the whole shop bowed to me. Warm and fuzzy.
My first forged knife. Friday afternoon this was a chunk of 1095 steel, a piece of wood and a stainless steel rod.

This weekend's projects.
A pair of zebra wood handled bush craft knives.

started work on a camp knife made from 5160 steel.
(https://i.imgur.com/EMzxLev.jpg)
This is the first time I've tried to use 5160. Up until now everything has been 1095.
Just finished up the knife that is shown on the grinding jig in the previous post.

Next up is sheath for it.
