The automatic feed on the Rong Fu is broken — more precisely, the piece that attaches the feed motor to the table is broken. It’s an old cast iron piece that just snapped.
I’ve started making a replacement part, but it’s going slowly. Until then, we’re all stuck spinning the knob.
The whole reason I was fooling with it was that the old bolts made it very difficult to put T-nuts in two of the tracks from the left. This fixes that too.
