Adding pulleys to slow down a Consew 206RB

[Samalan]

 To Highpower's point, I could run my clutch motor fairly well after a few years it was the constant humming of the motor it's not fun. Now with the new setup, the machine will punch through 8 layers or more of denim at the slowest speed the clutch motor could not do that at a slow speed I don't use my Juki LU-563 for leather for leather I use the Cobra Class 4. I will freely admit my addiction to these machines. For someone who's not in the business of sewing, I own a lot of machines LOL.
