Bunching, breaking, and loose threads on Leather sewing machine

This video goes through how to fix and adjust a leather manual sewing machine. I talk about bunching, breaking, and loose threads. I also discuss fixing the rubbing metal sound and properly threading the sewing machine. Please like, share and leave any comments you want. I will help where I can but if I don't know, I will be honest and tell you that. Maybe together we can figure it out.
