Thanks for the comment, Mary. Yes, I can go slow, but with conventional
foot pedal control the voltage drops going to the motor and with it the
torque and punching power of the needle and it stalls when I try to sew
heavier material, like canvas or leather.
I have a motor speed controller on order which electronically varies the
waveform of the ac signal and should preserve more of the power when I
slow down, as opposed to converting it all to heat like a conventional
control. I'll give a report later. JPBill

Odd. My machine seems to go through heavy fabrics like that much better
when I slow it way down. I guess they just all have their different
quirks, and we have to allow for or accommodate them.
