The fellow I bought it from was mostly into old cars and had no use for this iron and it sat rusting in his way. We made a decent deal and I lugged it homeward.
The surfaces of the in and out feed table were rusted and pitted and I did think about having them re honed at a machine shop but first I felt it better to run it to see what else was wrong.
About and hour with some rust remover from Lee Valley and I had the vital parts soaking overnight in dampened paper toweling or immersed where practical.
With a bit of elbow grease and some metal finishing pads on the electric drill I was able to get an acceptable surface on the tables.

At this stage I was confident that it could be put back in service. bearings good, tables flat, belt not so good,
pulleys, out of round and too small for the 3/4 HP motor.
After some help from the guys here I figured out the ratios for the upper and lower pulleys and swapped the drive system over to "Vee" belts which are wider and tend to run smoother.
I have a 2-3/4" pulley on top and a 6-3/4" pulley on the motor which should give me around 4000 RPM . With the 3 blade cutter head I will be getting close to 12,000 cuts per minute.
To get the motor to hang properly off the belt I had to rig up a hinge plate for the motor to sit on attached to the frame and on the unhinged end I made an adjustable rubber covered motor mount that I can set to take tension off the bearings and still drive the cutter head.

It was a bit of a trial and error as the inside of the casting was neither smooth or parallel.
At any rate, I came up with this:

Today I worked on putting a removable stabilizer leg under the extension and am fitting the sweep under the carriage to attach a dust collection hose.
