My 2 gripes with my BP clone:
1. Noticed that when i lift the knee with a dial between the knee and the knee slide on the column and i then reverse direction the guage would drop by 4/100 of a mm. Also when i lower or lift the knee it would sometimes shudder.
I have now tightened the gibs to the point where i am suspecting them of being too tight, but i still get the same problem. What is the proper setup procedure for the knee gibs?
2. The spindle is making a disturbing (hammering) sound when using a rosecutter whenever there is no tooth engaged in cut. It sounds like a key wearing out somewhere in the spindle drivetrain. when there is a tooth in cut the slack is taken up and whenever the tooth exits the material it jumps forward just to be knocked back as the next tooth engages the work...
Any advice to locate the problem with minimum down time would be much appreciated.
PS. I've got the variable speed head version.

1 Real Bridgeport will do the same thing when you adjust the knee, you aways should crank in down pass where you want to go and then crank it back up.
2 thats normal if you cut down the center of a 1/2" plate and have your tool on center you should put your cutter off center to get more than 1 tooth engaged or use a smaller cutter
