HOW-TO Adjust The Leadscrew Gears
- 8x12 HOME
- FIRST LOOK
- SECOND LOOK
After turning at 2000rpm and switching back to
620rpm, there was a light clunking sound like the gears were loose. As it
turns out the leadscrew gear set was coming loose from the pulley gear.
Here's how to adjust it (plus if you wanted to change the feed speeds).
|here's a top view of the leadscrew gears (closest to you) and the gear
that's on the spindle pulley.
it's difficult to see but the gears are

the other of the leadscrew gearing spinning (no spindle)

|there's a small socket head cap screw located next to the gear that drives
loosen it so that you can pivot the gear assembly.
|not sure if this thin 15mm wrench came with the 8x (probably not) but it
should have since they are thin hex jam nuts that regular wrenches can get
note that the gear set is tilted towards the front of the lathe.
|the gears were loose and after they were adjusted, we made certain that
the bolt is also tightened down.
it takes a 8mm wrench. note the
lubrication nozzle at the end of the bolt.
tilt the assembly back in towards the pulleys until the gear on the
spindle makes appropriate contact with the top gear on this assembly.
tighten the socket head cap screw.
btw, changing gears for threading and feeds follows the same procedure
Looking for mini-mill help and how-tos? How about lathe help and how-tos?We're prototyping a benchtop CNC vertical mill using the DigiSpeed-XL interface card for Mach, Dart Controls and KB Electronics KBIC/KBMM 90VDC motor controllers, 1.5HP treadmill motor from Surplus Center and a R8-spindle head from the X2 mini-mill - not to mention Gecko servo drives and an entirely closed-loop system.
