Hi Michael,
I found my 2" Pillow Blocks from ebay and came from Boltons??? in the UK. Make sure you don't mix metric and Imperial measurements,.
Bought Precision SS Shafts from

Not cheap but perfect if you haven't got shafts.
Nice project...can be a s simple or complicated as you want, I went for complicated
