I have a Record scroll saw which I bought new some years back at the wood show when it was at the Wembley Conference Centre. I have never done any intricate work with it just curves etc when the occasion arose. As Christmas is coming close my grandchildren have asked me to make some Christmassy decorations. They made this request also at Halloween but I failed. My Record has pin blades which requires a hole larger than some of the cut outs. I dont really want to change machines to one that takes pin less blades. Is there a device I can purchase to adapt my present machine?
