cheers lads
you should make one,
alloy from here.http://stores.ebay.co.uk/thebitsandpiecesplace?_trksid=p2047675.l2563
bike wheel spokes for the pins.
all you need is a drill /coping saw/few files and patience of a saint
just finished this tonight sps style without the quick change slots ,8mm alloy core /antler scales and glow in the dark powder.
and it was a total pain in the arse to make .
you might find a few here https://www.google.co.uk/search?q=slingshotforum.com+templates&espv=2&biw=1400&bih=949&source=lnms&tbm=isch&sa=X&ei=gfJUVPDHHcbLPczFgcgI&ved=0CAYQ_AUoAQ#tbm=isch&q=slingshotforu
