.............B and Q .................. buy some ply wood , sand paper , fret saw and rasp ( very course sand paper ??? ) . or find a tree make a fork some how . get some rubber off the net ebay ect . get a piece leather . you will need new bands sooner rather than later learn to make your own .
As it happens I have lots of off cuts of ply in the man cave. Is there a pattern or is it just cut from the eye so to speak?
