I just finished on of my Whacky Bags using my Singer 66-1. The machine works great, but I had trouble with the belt slipping, slipping, slipping ..... I shortened it by an inch and that didn't help much. It's an aquarium tube experiment belt so I'll get a real one tomorrow. That should take care of that.
OK, but how do you treadlers do the parts where you need to keep going and go slow????? I can go good on straight sections and gentle curves, but when it comes to start, stop, start, stop like I have to do with my bags it's a pain in the xxx. When I get to the point of going slow the machine want's to stall and spin backwards. Can't have that it screws up my work.
I'm hoping a new belt cures most of that.
I'm not a complete novice, but I could use some tips. Oh, and please no Youtube videos, I can't watch them with this sloooooow dial up I'm on.
