Step 4: Preparing Board and Trigger
Take an inch wide by 2 long out of the middle of the back of the board. Then drive a nail through from the side. Twist about 6" of welding rod onto the nail. Cut a slot out for the trigger into the track.
Secure the track, centered all the way down the board. I just put some lost head nails through some holes i drilled(small holes) in the track to secure it.
Bend the end of the welding rod into a slight hook, this will require tweeking later so it's not too hard to fire as well as not able to miss fire... ere on the side of caution. The pulling do-hickey is easy enough, if you can do better, then do it.
On the other end of the board, attach the 2 1x2 pieces of plywood using the 4 2" screws near the middle of the plywood pieces. Make sure the pieces are flush with the end of the wood.
