I haven't made my own yet, so I'm not exactly sure. But from the pictures it looks like he welded some aluminum washers to each side of the "gear". Bearings would be better, but I'm not sure if you can spot weld bearings without distorting them from the heat. But then again, this isn't exactly a precision weapon, so bearings probably aren't that important.
I think the purpose of the washers on each side are to act as spacers and also to make the "gear" more stable on the bolt that holds everything together.

Hi Andrey.
The gun looks awesome! Does it function well?
Any chance I could get a copy of the files you created and post them on the site (or if you prefer that I don't post them, any chance I can get them for my own personal use?)? I've had several dozen people ask me for them and I haven't had the time to draw them up (the plans I have are incomplete and have no measurements).
I'd also like to convert them into an .sla file and print them out on the 3D printer I'm putting together this week. I ordered a Makerbot Thing-o-matic and it should be here tomorrow. So I'm itching for projects!

The Rubber Band Gun is working fine!
I made the gun out of aluminum as a whole. But some parts of the mechanism should be made of solid metal.
I will give the files (SolidWorks2010). But later. I need to clean up the files.

I do not know how to upload the files to the forum. Please download it from my site and post them on your forum.
Some parts may require improvements during the assembly of the gun.
If you have a problem with opening the files please contact me.
Sorry for my English!

This is brilliant little machining project, challenging, yet a multipart mechanism that works well.

Downloading the files now Andrey. I will post them to the site when I have a chance. Thanks!
Any chance you could convert them to an .stl file (in millimeters)? My 3D printer builds files from an .stl file and turnes that into G-code. I'd like to try printing the gun just for fun. I would do it, but I don't have Solidworks installed on my machine.

Here are the Solidworks files. Andrey, you had trouble uploading them because you compressed them into a .rar format, they need to be .zip to upload here. No biggie. I un-rared and re-zipped.
I also see you added the .stl files to your site! Awesome! I was trying to find a .sldprt to .stl converter. They exist for Windows (eViewer can do it) but not for the Mac. The Mac version of eViewer won't let you export to an STL file.
Woot! Now I can print myself a gun! Awesome. Yorkies beware, your dad is going to be armed and dangerous soon!
…
Yorkies, hell … wife beware! Mwuhaha!
