So I got this. it's a treadle and AFAIK a Singer clone. Singer acquired the manufaturer that made this. Got it of someone who used it as decoration. I fixed it up to get it into a working state. But a few things are unclear:
When stitching through really thick stuff the flywheels inertia isn't enough to get me through the dead spots. I believe I can treadle. I can stop and start to my hearts contempt. Also if I want to go really fast the belt I made starts slipping. I guess i'll shorten the belt but it might also be that the machine just doesnt run as free as it should, any test one can do?
The lever in the base that has marks '1' and '2' or rather the mechanism it connects to is stuck and the linkage on the bottom might be a bit bent. What is it for?
Lastly the lever setting stitch length wont reliably stay 'up' for reversing and will bounce while sewing. Is thete something originally that keeps it in place?
