Lathe Painting - Part 2

Today, I was able to put the first coat of paint on the base:

Top of Base after first coat
I choose a light shade of gray than the orginal shown below for two reasons:
  1. I wanted to better match the shade of gray on the Bridgeport
  2. The lighter color should help maximize whatever lighting I can put up in the garage 
At this point, I think I am going to re-paint the external parts but the internal ones like the back cover and the motor mount plates will stay the original color. I will also leave the tail stock for later, since it's pretty easy to remove once I feel like painting again :)

In addition to the paining, I also did some more de-griming :

Lathe Motor Replacement


A while back I was fortunate enough to get my hand on a surplus 1.5KW (2 Hp) Brushless Servo Motor from Panasonic. As it turns out, the WJ200 series of VFD drives has firmware features to run a brushless motor in sensorless vector control mode. This means, that the servo can be used without using the encoder.

Lathe Progres - Base Cleanup and Painting

The last couple of weeks have mostly been disasembly and prep work. I have finally made some progress on re-finishing the Base:
