Looks very nice! You might want to use a harder steel for the knurling pins. The pins take a lot of abuse. I used M42 steel for the pins on the knurler I made. My knurler is attached to a rear mount plinth and has been great. Commercial better grade knurlers use carbide pins. The M42 is plenty hard - it is a pain to cut. If the O1 is hardened, then they should be ok. Normal O1, think it would be too soft.
 
This one is going on my wish list. Unfortunately I'm just finishing up a new shop so the budget is on hold for new projects for a few months.
