Thanks. I just PM'd Swordy, and I had attempted to PM BigmeatVX who had posted having the part numbers, but his inbox was full. I would like to make these available to everyone else if they turn out well. Do you know if they need to be heat treated? I can get 1" 4140 chromoly roundstock for around $3.50 per foot. Or 1.5" for slightly more. If I went for the 1.5, it would probably be fluted to increase strength and decrease weight similar to a high end rifle barrel.
