What job did you do today in your shop?

Just a hair over 1/4" is unthreaded is all.
5 full turns is the most I can get screwing the plate on backwards and there is only .3230"
or so left unthreaded yet out of .5300" of remaining hub left.
So, .207" more and I will be into the threaded portion, reducing the total overall thickness a lot!
It's at 1.35" now.

So I would leave .25 to .26 unthreaded. If you pass the .26 it will still use that last remaining thread and you'll be fine. I just wouldn't go past .25... each turn of a 8tpi thread is .125 so you have from .263 - .125 to err. Remember the goal is to seat the backplate on the stop. So even if you leave .260 unthreaded you are probably good. And if you don't like it you can take off more later.

Something simple, that took far longer than expected. Replaced a white wheel on my carbide grinder. Well, didn't have the right socket for it, 1-1/8". Found one at the local hardware store. Removed the old worn wheel and noticed the backing plate was around 1/2" thick. The new one, 1/8". Installed the old screws and found they interfered with screw heads deeper in the assembly. Wheel would only turn just shy of 90 degrees. Found some shorter 5/16" SHCS and mounted them, holding my breath. Had clearance for all 4 screws! Got it up and running again. Edit: add a picture.

I don't have air in my shop, so I had to drag an air line from the garage to the basement, about 100 feet. Used the impact wrench to take off the LH nut. And on minimum torque to put the nut back on.

Worked on making an adjustable bending/straightening jig for the press. Still got some work to do, but the hard part is done.

I'm having a problem visualizing how it works. Is it for round bars to bend, are each of the scallops a different size? Are they there to support the bend / straightening?

Yep. Basically I’ve got to cut two pieces of 1” round bar, and then make a die for the press. You place the round bars into any two cradles, depending on your intention. Then you put your die onto the press. Place the piece to be bent/steaightened in between. You can make different hoops, or rings, or straighten stuff. Here’s a similar thing.

got it. that explains a lot.

Did something like that about 50 years ago to bend tubing using different size mandrels and now use it to bend the lower drag links for my Cat 0 kits.

Cut the squish band on a Stihl cylinder.

I reckon I’ll call that done.
