Wheels / roller for wire feed

[zaaephod]

Hello all,

I'm building an automatic wire stripper / cutting machine. One thing I'm having trouble finding is wheels that are suitable for feeding the wire.

Any suggestions on some small wheels or rollers with good friction? I'll be spring loading two wheels to press against each other. They should be 2 to 2-1/2 inches in diameter, 2 inches wide, preferably with 1/4 shaft holes, but I can work with most anything.

Thanks!
