Unimat-SL DB-200 Motor/Spindle Bracket Modification

I may have said in the previous post that there would probably be no more projects on this lathe. Well that didn't prove true. I decided to do some whittling on the motor bracket. The reason for this bit of work is because the hunk of steel that encompassed the spindle was way too stiff, and the screw that clamps the bracket to the main spindle needed to be tightened a bunch for the clamping action to do its job. I figured if I removed some metal on the bracket, it would be easier to clamp. Here's what I started with. The red is the main part I planned on cutting out, plus a few minor touch-ups.

Unimat-SL DB-200 Tommy Bars and Marking (Zeroing) Pin

7/4/2022 update:
I did a little fiddling on the lathe today. I made two more Tommy bars. What I started with were two punch blanks that my dad had picked up from somewhere eons (50 years?) ago (or maybe he even made them in school shop, who knows). They had never been hardened, so I used two of them as a starting point.
