You sound like you already have what it takes to build one. A simple rollerbearing can be made with 2 pieces of pipe and use nails with the heads cut off.

any idea what pipe i cant find the right size

any 'hard' metal pipe - steel would be good... it all depends on your purpose.

its just as a model i was thinking inner race copper and outer race pvc just cant fid the right sizes
