How to I remove the center shafts or whatever they are called for painting?

I know this is silly. The problem isn't that I can search, but that I have no idea what the parts are called.

The pedal goes into a metal shaft, the cranks maybe, and then each of these have a bolt going into the center of the bike. Front hub? Searches for hub only turn up rear.

but between the crank and the frame there are these metal threaded things with teeth every 1-2" around it. How do I get that off?

Thanks in advance for putting up with this post

You mean the part the crank arms attach to? That's the bottom bracket, and there are several types. Since you mentioned the cranks bolt on, it will be a 3-piece crank- there are two crank arms and a separate axle in the middle. First, you'll need a crank puller to remove the cranks from the axle.

Next, on the left side you will have a lockring, which has slots for a C-spanner, or alternatively a hammer and punch can be used to knock it loose. The adjustable bearing cup is next, which has flats for a wrench. The axle and bearings will then fall out. On the right side, there is just a single bearing cup, which can be unscrewed with a pipe wrench or large adjustable wrench. This is reverse threaded, so must be unscrewed in a clockwise direction.

This link might be helpful for you too, you can drill into every part of the bike and see what the components are call and how to service (or in your case, remove) them.

As Monster said, that's a "bottom bracket", and there's several types, and several different special tools used to take it apart. Start here:

Thanks for the help everyone! This will definitely set me in the right direction. (it's funny, I swapped my car engine, rebuilt my motorcycle, and work on computers for a living but I couldn't for the life of me figure out what to search for to take this bicycle apart )
