Here's a couple of photos of the power feed on a Jet JVM-830. The power feed was originally on my Grizzly RF-30/31 clone. Bought the Jet and adapted the mill/drill PF to the Jet. You "should" be able to do the opposite with a BP clone PF and adapt it to your RF-30/31.
Just be aware that the RF-30/31 (at least my Grizzly clone) had 10 tpi on the X screw, so the power feed was geared for that thread. My Jet (like BP's) are 5 tpi. My mill/drill PF moves VERY fast in rapid, double the intended rate on Rapid. The pot during normal power feeding is always on the low end. You'll have the opposite condition with a 5 tpi PF on a 10 tpi mill so your rapids won't be as fast as if it was on a 5 tpi table, but still beat the heck out of hand cranking.
