In your first pic I'm wondering why it's so deep. Compared to the set screw in the third pic there can't be much screw in there. Maybe you don't have much of a head to wrench out. Sometimes I just don't waste much time & just do what Daniel mentioned, it's always worked out good for me. Let us know how your doing. By the way the job you done on the rear end looks great. The black & silver barks !

I have replaced set screws on some pulleys with a bolt.  Had problems with a set screw  on my old post drill.

Drill a dimple in the end of the bolt just like some set screws have.  Able to tighten the bolt better and easier to remove.

The set screws are inset on the center mandrill, and almost flush on the outer mandrills. The plan is still to seek professional help.

I have a set of these. Wonder if they would work?

Because they are so hard, They are very brittle. Impact wouldn't work on them, I don't think. Maybe wrong, but I can see breakage.

I think you would've had better luck with oxy acet. torches and a rosebud. More heat and quicker on large pieces will often help where map or burnzamatic can't quite get there.

Have you tried the hand impact in the TIGHTEN setting?

 

Sometimes giving those a good sharp hit or two before trying to back them out helps.

The evitable rounding has happened, the 5mm and 3/16 bits just spin in the set-screw. I need to remove the mandrills from the deck so I can go to plan "B" (I had a sneak peek in Santa's bag) and I think I saw a bench drill press in there   Plan B will have to wait till after Christmas, but there is plenty of other things to work on.
