I have this roller foot that does not fit my 801 bell skiver. There's not enough clearance. Can someone tell me which model/brand it will fit, or if there is some modification I can make to my machine, though I don't see how this would be possible, as there is an issue with physical clearance?
That roller foot is intended for a machine that has an additional attachment on the back of the machine to spin it.
Here's how it hooks up, and what the machine looks like:
My model is a Japanese Nippy NP1. When the machine is feeding, the back part spins along with it. This means that the roller foot is fed by a different gear than the cutting bell. When purchasing the machine though, it hooks up the two sections so that the foot pedal controls both speed and feed.
I had to add a second motor to it since by default, you can't control the feed speeds.
Edit: Looking at pictures online of other NP1 models, it seems like some include the back feed and others don't. I'm not sure what the difference is. I bought mine very used and rebuilt it entirely.
