Need advice on many Singer 111w151
I purchased a Singer 111w515 to upholster my 30 Ford roaster. I have a Singer 99 light duty i used to make door panels on my sedan, it has reverse. I got use to that for starting and competeing stitches.
Could the 111w be wired to run in reverse to lock stitches?I have a varack that i use to slow various motors with brushes down or up. Wonder ing if that would work to slow down and or provide greater control?
Also, where can I find an instructional book. Want to be sure I've threaded it correctly, including installing the bobbin.
Thanks in advance .
