Bridgeport Mill for the Garage - Part 2 Head Disassembly

The mill is in need of some maintainance. Here is a short list of the items that need to be done to the 2J head:
  • Motor Pulley bushings need to be replaced
  • Spindle Brake is worn out
  • Colet set-screw needs to be replaced
  • A couple of the upper section bearings are a little noisy
  • The Back gear needs to be re-greased
  • The belts probably need changing as well
 The easiest way to get all the parts needed was to order a rebuld kit from H&W Machine Repair.
While waiting for the parts to get here I started to tear down the head assembly. Here are all the pieces:
Motor and Variable Pulley

Upper Housing

Front Pulley and clutch shaft

Lower housing and Brake. Brake Dust still needs to be cleaned out

The rest of the Mill, looking a little naked rignt now

Spindle assembly removed from Quill. It only needs some new grease and a new set screw.
 The other outstanding issues are hooking up the Electrical System, fixing the X axis DRO scale and figuring out the backlash in the X axis.
