Perfect! Thank you!

Thank you! This is what is now my understanding: Brushless servo motors have a high startup rpm's so it is recommended to use additional speed reducers with a smaller motor pulley. Brushed motors do not require speed reducers. Likely motors that come with 1541 are brushed - This is my assumption Getting "S" type, the safety clutch is recommended Items like bags are best done on a cylinder arm machine. You can turn a cylinder arm machine into a flatbed machine by installing a flatbed attachment. I think I will go with 1541S and with whatever brushed motor it comes with to learn the trade. I can always upgrade the motor to brushless later if I see the need (after some paid job 🙂 ). I will focus first on items I can do with 1541S. There is lots to learn. Thank you for your help! If I missed anything please let me know.

My main focus is automotive upholstery but I would like to learn how to do things from leather. I am thinking of belts, bags, probably made from not the thickest materials. You suggested a speed reducer pulley and replace the servo motor pulley. Are you referring to a speed reducer showing on the picture below?

One retailer told me that the "S" version with the safety clutch, when new, the spring is too strong and it does not engage when it suppose to. With age, the spring gets weaker and engages even when it is not suppose to. The non-S version is cheaper by $75 which is not that much but I hate to spend it if it does not work well. What do you guys think?

The situation about motors is very confusing. Juki does not state any information about the motor they include with 1541. Some retailers install their motor, some motor, and some claim that they provide with the one Juki provides. Are all these servo motors brushless?

Hello! I would like to learn professional automotive upholstery and leather-working. My plan is to purchase Juki 1541 and purchase a 12 coil motor separately. I assume that the Juki provided motor is 6 or 9 coil motor. 12 coil motor is supposed to provide a higher torque and should be smoother. I came across Reliable SewQuiet 6000SM, 120V, 550W, digital speed controller, 60mm pulley, 7.8 lb, made in China. I wonder if this is a good idea and if there is any other motor I should consider. Any thoughts or suggestions are appreciated. Thank you!

Hello! I am new to leather working and wonder how would you wrap bicycle bar ends with leather? Please see the attached picture. The bar ends are not a straight rounded tube, they are slightly deformed. Thank you!
