Thought i would share a slingshot crossbow i made today,
Basicly consists the same trigger design as JS's crossbow with the addition of rollers that uses tubes instead of flatbands.
I've always wanted to build one, one typical day on the slingshot forum chat, couple of members and i had a conversation on benefits on roller functions and such on slingshots
and after learning and noticing the performance myself. I finally decided to make one with long fork extentions mounted on a slingshot crossbow using Dankung tubes as my primary.
The intial build itself was easy with common household tools.
Materials was very minimal also.
L.Q plywood
Aluminium flats/tubes
Mild steel bolts/SS bolts
Nuts and screws.
The nylon rollers i brought was from the hardware store used in sliding doors which is 32mm dia, depending on the rollers you get.
Out of the package the rollers are somewhat stiff, however a quick burst of silicone spray did wonders. Not bad for $6 for a pair and suits the tubes very well indeed.
The performance increase is noticeable, however i'm not to sure on the consistency/accuracy in these early stages.
A pair of guards infront of the fork to stop the tubes coming off while releasing the pouch will be needed.
Simple stock would be nice also
However this thing is a blast to shoot with, and was equally fun to experiment with something different.

If you want some more inspirations check some of JS vids on slingshot rollers, they are quite worth to watch.
The Nylon rollers bolted down to the SS bolts
There is room for improvement, suggestions/criticism is most welcome.
