Joined: Feb. 2006 Posted: Sep. 18 2006,14:42 I've been building this for a few days now. I wasn't sure if it was cool to post it or not since it's not really a gun. We do have some other things here, so I figured what the heck.



Been fun to build, working off of bad pictures and trying to reverse engineer the thing from them. I got some suggestions from a few people here that I ran with. Thanks guys. I had some 1" AL rod and some schedule 40 AL tube which is what most of it's built from, the tines are home depot flat for now, and the trigger block is 1/2" plate. I'm going to build a trigger from the plate since I don't have any sheet metal sitting around. I still haven't found a spring.



The majority of it was easy once I goofed up once, the launcher tube threads were a problem since I didn't have a pipe center and stupidly thought I could do it without a rest or any support. The knurling was also attempted without one. Live and learn. I picked up a live center and made a plug that fit snugly into the pipe to support it. Seemed to work well. The trigger block was a one shot and was much easier then the BOSS barrel since I'd had some 4 jaw chuck experience. Marked drilled, bored, threaded then milled. I just hope I don't mess it up when I drill the trigger and safety pin holes.



I used the lathe chuck to determine the placement of the tines, layout blue, then squeezed it down tight. V block on the mill and they were cut with 1/8" 4 flute. The cap to lock them in place needs to be remade since I wobbled with the die and it's slightly off. I believe that the hook portion of the real one is larger then 1" diameter and if I had some 1 1/4" rod I'd make a new one.



Still looking for a suitable spring to try it out with.





Now I have to get back to that MKII and the BOSS grip.
