Subject: My (new) Bolt Thread

Im not shying away from Delrin b/c of y'all at all, nor am I shying away from it at all, Ive just decided to use MDS Nylon, which is another self-lubricating plastic, only supposed to be a little stronger. This came from another friend of mine, who really knows his stuff.

As for the weakness of a plastic bolt, I see no harm in it, have you ever looked at a spyder, they have tons of aftermarket Delrin bolts available. Also Delrin and/or MDS Nylon, is not a "soft" plastic, its quite sturdy. I looked at "How the F4 Works" and its a neat drawing, but there is no binding on the the bolt or bolt pin, so really the bolt is getting pushed forward by the spring, then pushed back from the blowback of the valve.
