Really enjoying this thread, 'cuz shop pictures are some of my most favorite-est!
FTO- That surface grinder restoration is awesome, it looks fantastic!

The giant 52100 bowie/fighter won out the
ADD focus challenge LMAO. In my first post, the blade was heat treated and had a few licks against a 120X disc. Fast forward to this photo--- it had been completely finish ground all the way around, and I was doing hand finish work-
Here's the result of the hand finishing. It's what I call a "dirty" finish, because it's all at one grit, but not quite as uniform as it can be (or at least as I can get, LOL).
It has some contrasting finishes (on purpose
)... The main bevel is 320X, the clip is 800X, and the spine/choil have been rounded and mirror polished.
Those bearings? You guys didn't like my description very much eh?
I'll start calling you guys dzvwhatever his name is HaHa! j/k
The bearing are for a very small--- small wheel for the KMG- If you happen to notice the finish looks a little different on the left side, that's because the first time I fired up the grinder with this, I didn't realize the belt was hitting 2 stand-off screws on the bottom of the small wheel attachment. The screws forced the belt to wrap inside and abrade the left side of the wheel.
I don't have super high hopes for this, because a contact wheel really needs to have some type of coating to grind smooth, quiet, and give the best finish. But this is it anyway-
Just for kicks, here's a big, fat FAIL that has to be redone. I was trying to build a recessed disc on the cheap. I made the
silly mistake of using two layers of 3/4" plywood for the bulk of the disc. Even though the disc was faced and bored in the same set up with single-point tools, the funky layers and holes in the plywood make this thing run like a rock tumbler. Grrrrr... Oh well, back to the start on that one! LOL
edited to add*** Yes, there's a steel hub on the back of the disc. I didn't just drill a hole in the wood and shove it on the motor shaft.
