I have been toying with this idea recently and last night after watching a YouTube video decided to try and bodge something together.
I started off with the following materials:
1 x Standard fishing catapult
1 x 1/2" PVC pipe
1 x 1" Slipring
Paracord
Leathermans sewing twine
Epoxy glue
Superglue
Firstly I cut a piece of the PVC pipe just slightly wider than the Y in the catapult frame and cut notches in both ends.
Secondly I cut a slit in the top of the pipe big enough to accept the slip ring and sunk it in.
Thirdly I then put the PVC pipe between the frame and secured it using an over under on either side and then used expoxy to harden the cord and secure the piece. This now becomes a structural cross member.
I then put epoxy on the slip ring and sunk it into the slot in the PVC pipe, wrapped it in leathermans twine and used superglue to harden and stiffen the binding to stop the ring moving.
I then left this to all set overnight and gave it a quick test this morning. Even with the rubbish standard bands I managed to shatter one of my 24" home made shafts on target impact which is illustrated in the picture below.
And finally I make shifted some flecthing using duct tape on my next shaft.
All in all I am really impressed with the power and accuracy of the set-up up to 25 yards. I have numerous ideas on how to improve the concept and I will hopefully over the weekend get a video up of me using this for some target practice.
Also I think this is an ideal, multi-use tool.
