I am trying to cut a spiral into 1/4" plywood. I have the layout OK, but trying to get a smooth Arc is very tough. Both the jigsaw and bandsaw are prone to wandering. Does anyone know of how to cut a smoother cut? Maybe a roto zip tool would be better but how do you keep the cut arc even?
The spiral is 1" wide and starts at 12" in dianeter.

Perhaps you might just cut the arc as well as you can, as close to the line as you can without going over, and then use sanding to finish to the line.

Thx for the answer but sanding is impossible because the spiral is 12" in external diameter and spirals inwards on a 1" wide strip. It's a spiral "drain" part for a kids marble maze project which is quite hard to make. Lots of compound miters, etc

You need the classic stationary ....... Scroll Saw.....the standard tool in every 'shop' class.........

.....Fine blades......Eye/Hand co-ordination

Your blades are too wide to cut the curves........

A roto zip would work if you have a steady hand but I agree that the scroll would probably be the best bet for a fine cut.....MJH
