I've done a lot of work to my HF bead roller. BUT the first thing I should have done 6 years ago was to drill, tap and add grease zerks to the "bearing" blocks. I am up to the farm and don't have part numbers but I bought the orange "skate board" type wheel From Reid supply for the botton shaft, it was a good fit. For the top I bought a 22 MM "Browning" type hub and V belt pully from Burden's surplus center. for the top for a tipping roller. I have been gathering up pieces from old farm machinery, a box stapling machine for making 50# cardboard potatoe boxes into a dedicated thumb nail shrinker, old sharpening machine into a mini pulmax, parts from grain planters into a slip roller. Hydralics from an old tractor into a louver press.
