Interesting idea, fun to idle away an evening I'm sure..... but when the fascination starts to slip away...give me your address and I'll send you an almost new jig saw.
Best regards, David

> I read recently that an easy but tedious method for cutting a circle is to

> 32 sided polygon. Somewhere around 16 or 32 sides you get close enough.
> Needing a 211/4" particle board disc I decided to try it. I made a straight
> edge to use with my portable circular saw by screwing and gluing a nice
> straight pice of 3/4" ply to a piece of 1/4". The 1/4 plywood is left over
> wide so that when the saw is run along the straight edge it gets cut off.
> This means when you lay the straight edge on the board of you're cutting
> the cut will be at that edge.
> Using two spring clamps makes clamping and moving the straight edge easy.
> So getting my circle went quickly. There are more cuts at each stage but
> they are progressively shorter so it's not so bad.
