I have been searching without success for a powered tool that used to be known as a "Jig Saw", but all I am finding are devices like powered small hack saws, with hack saw type blades. No good for tight curves.
Remember when you could buy/make real wooden Jig Saw puzzles, from 1/4" thick ply, with intricately curved interlocking edges? The then-Jig-Saws (my Dad had one) were very compact and with slim cutting blades circular in cross section. You could glue your picture to the plywood, mark out the jig saw pattern, then cut it all out. The blade vibrated.
I am looking for something similar to do intricate model woodwork, especially deck plank edging, where you can pause, turn through 90', and carry on. . . . . At least do tight curves.
Any ideas ?
