Made me a nice scroll saw using the orbital jig saw works awesome I don't seem to need it but I am going to put guide bearings on a arm at the top of the blade as I seen someone in Russia do on Pinterest's. I needed something to cot 1 1/2" hard wood my Dremel Moto-saw was good 3/4" at best hard wood and still break blades plus it could only cut 11 1/4" I can do 18" after I put the Arm on.
