thanks for the complements guys. the roller was actually 2 sections of 6" sch 80 pipe that I found in the scrap yard. Cut them to length then welded the to pecises together to make it about 5' 10". then I cut out the end plates from 3/8 plate and put the 1" solid shaft through it. But the shaft is not full lenght because that would cause it to bow in the middle so instead I made two parts for that look like this l----l- and they slide into each end. As far as the spikes on the roller they are 1/2 " round by 1 1/2" long. They are spaced 3" apart and are 8 around making for 192 very tedious welds.
