Paper towel wetted with rubbing alcohol. Provides a surprisingly tight grip.

I have found a wipe of the hands with a paper towel wetted with rubbing alcohol, as well as wiping off whatever you are trying to undo helps a lot.

juice is slippery stuff!

I'd knock off a bit of the thread sharpness with 600 wet or dry paper first, then maybe grab some buffing compound for stainless steel and go to town on the threads a little at a time till they threaded without much force.

As long as you don't cross thread the parts will screw together better after a lot of use, the sandpaper and polishing compound are just trying to clean up 0.001" or maybe 0.0001" imperfections not major threading problems.

As long as the threading is the same (which it should be) you should be able to get the parts to screw together with a little cleanup of the threads.

You can also get chromium oxide paste or in bar form to help accelerate the polishing of the threads, coat the threads with a small quantity and beginh working the parts on and off as much as is needed to smooth them out. You may want to clean the threads every 5 or 10 passes to get a better idea of your progress. There is not a huge quantity of skill needed to get the threads buttery smooth feeling (they may not look great on very close inspection, that depends on how bad they were to begin with), just add a bit of push or pull as you thread the parts together (just like you would for a child safety cap). This helps quite a bit in my experience when polishing threads.

I wouldn't use diamond abrasives unless the fit was truly way too tight and even then I'd be extra careful as diamond is a very agresive abrasive.

When I lengthen the top pin, it no longer makes contact with either my Igo or my pt2 rebuild.
I don't want to have to spend any more money on something that's supposed to work properly in the first place.

Given the topic at hand, this statement is making my eye twitch. Not gonna do it though

After reading about the first two threads catching, I guess I just need to really force it.
But now I need to find a good way to grip the tubes. Because I just sliced the ever loving .... out of my hand on the edge of the tube. It's going to require a whole lot of force to thread it.

Pay attention to the above advice.
Even a simple Fine lapping compound or Graphite(lock lube) will assist in cleaning up threads.

DO NOT use excessive force. You will only end up with 2 pieces seized together and a ruined Mod once you get the pipe wrenches to free them.

Twist until stiff and turn back out
Repeat, repeat, repeat

Your mod could actually have a bit of cutting debris in the threading. This is why I fully strip, ultrasonic clean and inspect before use.
