Drag Knife - turn your CNC router into a vinyl and box cutter

In this jolly old episode we make a drag knife. If you did not know its a type of cutter that fits in a cnc router. Once installed it can cut signs and cardboard etc etc. I needed it to make cardboard boxes and parts for a few products. Being tighter than a Lamborghini head gasket I could not bear to part with lots of beer tokens to buy one so I made one instead. Bit of a learning curve but damned chuffed with the result. Slicing cardboard with a guillotine took around two hours this does the same thing more accurately in under 30 mins. So worth the time taken to design and make it. Cost wise it was pretty much free, prats came from scrap bin ( bucket of broken dreams)! Hope you like it anyone wants the design give us a shout. Cheers
