Making roller and/or trainer??
 

Has anyone ever made their own rollers or trainer? Im the do it yourself kind of person and they seem like one of the easier things to make. I know it would probably be easier and cheaper to just buy off of craigslist, but making it yourself is 10x more fun.

Rollers would be pretty easy to make.

yea ive been thinking of an adjustable design using metal pipes and skateboard bearings.

Only thing with a trainer is idk how to get the resistance
