Greetings!
I just got a 31-15. Is it possible to sew leather, canvas, fire house etc. with this machine...with a Singer foot treadle? Or will the power of a Servo motor be needed? Maybe the pulley wheel of the treadle could be replaced with a heavy flywheel? I've seen a multi-tool (scroll saw, mini table saw, sander etc.) made from a foot treadle which utilized a heavy flywheel (25 lb. dumbbell weight) in place of the pulley wheel.
Thanks, cheers, Mark
