He sells SPAD ARFs and he sells spare parts. I'm sure he would have what you need. Tell him Marlowe referred you to him. FYI I have many poly plastic firewalls using a jigsaw running at slow speed. If you run it at normal speed it will melt the plastic and make a mess, but slowed down with a speed controller you will throw chips rather than melt the plastic.
