My Benchmaster Horizontal Milling Machine

Below is an assortment of images of my Benchmaster Horizontal
Milling machine. It takes Morse taper #2 collets using a drawbar
and came with two arbors (7/8" and 1"). These pictures
have been posted to help other home shop machinists in identifying
or setting up their machines. Enjoy. Below is the original drive
setup.
Since I made the above images, I have modified the
drive system to provide slower rpms for larger cutters. The images
below illustrate the drive system as it is now. This new system
provides three slower speeds. Only three of the motor pulley steps
are used (I already had the pulley). This drives a ball bearing
idler pulley which, in turn, drives the spindle.
In the background can be seen
the idler pulley support arm.
Well, there have been additinal changes/improveents
to the drive system with the addition of a three phase gear otor
and VFD. This is the current and final drive system.
Here is a video
of the machine running at slow speed in the pulley low range.
Here is a video
of the machine running at high speed but still in the pulley low
range. Much higher speeds are possible.
