BB gun bearing.
 

My idea is take the stock knuckles and swap the nylon bearings for steal bb's:

And i should work like real bearings that are expensive as crap on ebay.

Hope this is easy to do!
(I will add more steps when i get pics of it.)

What is going to hold the BB's in place?

The ridge that holds the stock bearings in.

You do realize how difficult it will be to get the BB's in there without them falling out?

Yeah but it's worth a try instead of paying 30+ for bearings i think.

You could try puttin a dowel rod through the middle opening, loading the bbs and then pushing the axlestub in as the dowel rod is retracted, it would be about the only way to load them in. Even then if the circumference of the bb is smaller than the width of a bearing they will fall out.

You might just invest in some graphite to put on the stock bushings..

True but i will try it none the less......
