Hello, my first post in this forum.
Just bought an old Pfaff 145 H3/1BLN with a clutch motor. For my hobby activities I do not need the speed this machine can offer, and I want it to stitch slow.
The mechanical brake of the cluth motor I want to keep. The plan is to change the ratio from 1:1 to 2:1 by altering the pulley sizes. Lock the clutch by pins mounted in to the flywheel of the motor through holes in the friction disc. Control the speed of the motor with a VSD (variable speed drive /frequency converter).
Anyone gone down that route?
Thanks John
