My wife has a couple Sentro Knitting machines, and she had an idea for an "Improvement."
The machines have a small hand crank that turns the mechanism that does the knitting. She heard that some people were using adapters on a cordless drill to connect to the hand crank, and asked if I could design/print something for her to use. So I did . . .
I made one for the big knitting machine, and one for the small knitting machine. I designed it so that I could use a simple carriage head bolt/washer/nut combo, and we clamp the drill on the threads of the carriage head bolt.
