I cut in viens using an skill 9.5 blade , it did very good with the pine, it didnt try to wonder, it runs at 1750 rpm , the motor on my montgermery ward scrollsaw is one speed, its built in 70s runs quite and smooth. My set up is kind a made up of things I have laying around, cheap but gets job done. Ive noticed if you want to keep your blade from wondering on soft wood like pine , use the sharp end of your circle compass to draw your lines out, the blade will follow it. wtg
