I got an assignment from the wife, please cut the old plastic fan blade in the shape of a dragonfly wing for an outdoor decoration she is making. I thought to myself , well the scrollsaw should work great! I loaded a PS #9 skiptooth in the saw and off I went. As you can see the cut went fine. However, then I became perplexed and chuckled a bit. Apparently the friction from the blade heated up the plastic to the extent that it essentially glued itself back together.
So Here I sit wondering now what. I tried recutting the line and quickly inserting a small wedge to create a gap, no luck. Plastic too hard to cut with a utility knife. A chisel will not split the two pieces with out significant force which worries me.
Any ideas?
