Alan:
Thanks - I keep learning stuff from you.
I built a circle cutting jig for my band saw which will do the cutting but this tool will come in handy to draw the outside arc so I can set up the band saw plus if I need a 'one of' I can use it to cut also. Like Myles I did a google search and found a bunch on Ebay ranging from $30 to $60.
Question - you seem to use box cutters instead of Exacto blades to cut plastic - preference or a reason?
Joe
