I am cleaning up a P-83 but I noticed that the adjuster knob/screw is bent. I would like to try and bend it straight again and would like to remove the knob/screw entirely and try and hammer it straight on a vice.
It must be able to come apart but looking at it I see no obvious way to take it out.
Does the upper (knob) section unscrew from the lower threaded section somehow?
any help would be appreciated.
"Does the upper (knob) section unscrew from the lower threaded section somehow?"
No, they are not intended to come apart. And, don't go hammering on the threaded part or clamping it in a vice...you'll ruin the threads. You might try putting several nuts of the proper thread size on the threaded part and then clamping those in a vice.
If you have a soft jawed hobby vise you can straighten it in the manner you were thinking. I've had to do it on a couple of occasions. It gets the large bends out usually, but it may not get it perfect. sourcing a better one may be the better way to go if it really bugs you a lot.Walking
Good point. You could probably use a couple small pieces of soft wood like pine to line the jaws of the vise to grab it enough to straighten too. Basically making your own soft-jawed vise. I have wood cut that I can bolt in, instead of the iron jaws when needed.

I actually have rubber hard rubber inserts for my vice that I could use. Thank you for the info on the bolt no being able to come apart.
So I guess I I can just take the slide off and turn the bolt 90 degrees and then clamp it that way. and yeah I had already thought about the threads which is why I haven't done anything yet. I knew someone here would give me some good advice so thank you again!
Well wouldn't you know it. I used two wood blocks in the vice, I got out my hard rubber/plastic mallet and got it cinched down nice and tight. I even took a lot of time to mark with a sharpie the exact spot to strike it.
Gave it a nice sharp rap.. pulled it out of the vice and found I created an opposite bend on the threaded part (when the orginal bend was above the threaded part) about twice as severe as the original bend creating a nice "S" curve.
Fortunately I was able to use almost the exact amount of force, and a few taps on the opposite side to get it back to straight. Then I had to go to work trying to correct the bend higher up. It required a lot of light taps while holding it against a wood block with my hand at just the right spot. The vice ended up being pretty much useless. I got a much better and it is good enough you'd probably never notice it during normal adjutstment when attached to the drum. But when it is off the drum and you turn it rapidly you can still detect a bend. Although I would never be able to determine exactly where to hit it anymore. It is that close.
Anyway here is the finished product next to the original photo from the ebay ad where I purchased it.
Steps followed were:
1. disassemble
2. Soak in dishwashing liquid for 36 hours
3. rinse and clean with paper towel
4. scrub trouble spots with aluminum foil
5. scrub even greater trouble spots with 0000 steel wool.
6. Polish with simichrome
7. grease moving parts with lithium white
8. re assemble

That certainly cleaned up nicely.
Wow! Nice job...came out really good.
VERY nice, looks like 2 different throws!
