Automated Foam Cutting System, with weight driven bow Thank you to Scotland's Neil Gillies for the following design.  Neil has moved on to automated foam cutters using CNC control.  He had published these plans a few years ago and has forwarded them so that folks who wish to build their own version of the foam cutter may do so.  I use a commercially available foam cutter from Tekoa, called the FeatherCut.  It is a quality tool but commands a quality price, for those who wish to have a good foam cutter at do it yourself price you can't go wrong with Neil's design
		This is what the foam cutter will look like when you finish it.  The electric leads that attach to the bow are pulled down by the bar at the bottom. One of the leads is set to the end of the bar for the root cut and travels at 100% speed.  The other wire for the tip is placed at a lesser percentage and therefore moves slower so you get smooth cut working by yourself.
