As far as clamps go, I highly recommend getting in touch with forums user "bjesson". He makes clamps for the 2400, 2401, and the Colt out of Delrin at a very reasonable price. I weighed the options...time and effort expended designing and manufacturing clamps for my 2401 (and possibly screwing up pricy materials in the process), or just getting some of Bill's. Easiest decision I've had to make for my build so far. Wouldn't hurt to give him a shout!
