I aquired a large amount of 3/8 o.d. and 1/4 in. i.d surgical tubing.
This stuff is great. It is very powerful.
I am using Jack Koehlers method of hooking the tubes to the pouch. In his book,
pgs. 54 thru 55...it shows how to use a separate piece of tubing, to slip the ends through,
to attach the pouch. It is a superior attachment compared to store bought sets.
The reason is ,that with this method, the pouch will not twist up after multiple shots like
the burn thru hole attachment does. Also, this method does not deteriorate the strength of the tubing by making a hole through it, at attachment point.
If you dont already have Jack`s book ``slingshot shooting`` I suggest you get it.
Lots of valuable information about slingshots. I had my book signed by Jack at the Alverton tournament, and I got to shoot along side him. He is a great guy.
