Hey guys, have started digging into the inoperative powerfeed on the quill of the 2RQ-3-28 I got from JB Bergman a couple of years back. I have some major fab work ahead of me to re-create an entire missing shaft and gear cluster. There are some other minor parts, but this is the biggie.
This cluster includes the worm wheel that drives the powerfeed off the worm on the spindle. I have a brand new minty worm, so at least I have enough of the puzzle to get the figures on the mating part, but does anybody have an idea what material that worm wheel is made of? I'm kind of guessing bronze. The feed mechanism should be the same as a 1RQ or 16S.
Thing is, this 2RQ head has a top speed of 3400rpm, so this is going to be pretty critical. The power feed worm and gear are constantly engaged, so no way to only use it at low speed, unless the shaft and gears are removed every time it is run at high speed.
