- Feb 1, 2009Hi Denis,Good deal - I'll shut off the main motor on mine and take a closer look & listen. I did notice the dial is a bit off, (similar to your system ?) but ignored it.Again, thanks for the reminders.Take care,DBN

Subject: [mill_drill] Fixing a rough running Power Feed.
Date: Sunday, February 1, 2009, 4:19 PMHi All,
Ever since I received my G0484 Mill back in Sept 2008, turning the X
Axis handle has never been as smooth as the Y Axis handle. There has
alway been a single spot in it revolution that it would stick. Today I
decided to investigate and see If I can find the problem. I don't
expect the X handle to move as smooth as the Y handle because of the
Power Feed motor. I took the motor off and removed the gear off of the
X Axis shaft. I then turned down a 3/4" shaft to 17mm to match the hole
in the gear. Without removing the shaft from the lathe chuck I
installed the gear on the end of it. I then very slightly touched the
gear with the lathe cutter and turned the chuck by hand to see if the
gear is round. Sure enough, it was out. I proceeded to cut the
circumference of the gear until it was round in relation to the center
hole. It didn't take too much cutting to make it round.
I also indicated the shaft at the motor end of the Mill table. It was
dead on, no problem here, but the X Axis handle was still dragging a
little. Taking a closer look at the dial at the motor end of the table
I noticed it was slightly crooked. I removed the dial and faced it a
little in the lathe and reinstalled it. Without the Power Feed
installed the X handle moves beautiful just like the Y Axis handle.
I reinstalled the gear on the X Axis, installed the motor and put the
Power Feed through it's paces. It ran very well and much quieter than
it ever has. It always had that oscillating sound, smooth/grind, smooth
grind. With the gear nice and round the sound is consistently smooth.
The hand wheel is much easier to operate now.
