Axel?
 

After reading this very informative thread, I decided to buy the parts to build the dolly...however can someone tell me what type of screw/bolt "axel" I need to connect the wheel bearing to the metal mounting plate? (anything will help...size, model number..etc..I assume I can just use a certain type of nut/bolt combo for this)

Thanks!

Here's what I did:

First, I went over to the local skating rink and offerred to buy 8 used wheels and bearings. They were nice enough to donate all eight wheels and bearings. (Thank you Skatetown).

Then, I went to Home Depot and bought some bolts that fit perfectly into the bearings opening. Then, I bought some standard metal L-Rod, or whatever you want to call it. Basically, it was a 10" long piece of metal that was bent long-wise so that each side was about 2" in wide.

I then cut that into four separate pieces (one for each corner). Then, I drilled holes for the wheels. I needed some spacers for the wheels, because they were too close to the L-bracket. I just used some hollow piping for that.

I don't have any pictures of it, but you can see it an action here:

Thanks Russell...yah I pretty much have everything I need (the L-brackets, etc) I just wanted to see if anyone had exact measurements for the bolts that go into the bearings so that I don't have to hunt for them. No biggie though. That was only thing I'm was even remotely concerned about (the rest is very easy)

Oh, thanks for the video as well - I REALLY liked the dolly shot at the end where you fade to different passes of the couch. Very well done. The only shot that I thought was a little bit weird (if I may be so bold) was the POV shot. It looked like it was on a tripod and not quite in the right position (probably a handheld shot would have been more effective..?)

Thanks for the feedback on the video. You're right. The POV shot didn't work very well. I'm actually pulling it from the production. I'm shooting it a different way.

Hope the dolly works out. I was able to build mine in a couple of hours for about $40. I also bought a tripod base to mount to the dolly for better camera support.
