Is it worth investing in bearings rather than just drilling holes for the axles to go through?
If so, where should I purchase bearings and which ones would work best?
If the past two are true, how do I apply the bearings to the chassis?

I'm sorry for so many questions but regionals are appoaching quickly and I still have no idea what I'm doing (T-T) :cry:

1) Yes! Might be a tad bit costly tho.
2) Amazon sells a lot if you're on a tight budget.
3) Make wooden/3d printed hubs, or drill larger holes for the bearing to fit in, and glue it.

You can message me if you have any specific questions, I'm happy to help.

Because of the low weight and relatively slow speed,low friction bushings will work very well. Go to IGUS and fill out the information for the Y.E.S. program and they will send them to you FREE!. They have both metric and SAE sizes. They also have bearings, but that is quit a bit more work to do well and is not necessary.

This doesn't have much to do with wheels, but I didn't want to clutter the forum, so I just stuck it on here...

I'm using threaded rods as axles, but I've run into this problem where spinning them causes the entire axle to move in that direction, as well as all of the knuts and gears on the rod. I cannot for the life of me figure out how to hold the axle in place without choking it's rotation entirely. How do I do this?

You can try using 8 nuts in total: 4 on each side, 2 on each side of the hole. Use the two and tighten them against each other, locking the two in place. Repeat 4 times.

Green lines are nuts. Tighten those against each other. Red is the threaded rod, and black is the chassis.

So sorry, but what type of knuts? Hex nuts? Wing nuts? Lock nuts?

Anything should work, I'd try regular hex nuts though.If they come loose, try lock nuts.
