Dave, thanks for tuning in.
The gear hobber is a Barber Coleman #3, mid 1920's version. When I picked it up, it was a sight for sore eyes. It was set up for a line shaft. The first thing I did when I got it before it was even unloaded from the trailer was a trip to the car wash. under the dirt, the machine was actually in fairly good shape. I replaced a few bearings, and a few other parts, set it up for an electric motor, and went to ebay for some accessories, change gears, and hobs.
The machine is a little more than 4 feet wide, and high with the base.
The machine is capable of making helical and spur gears up to 6" in dia. Each dp is cut by an individual hob, and that hob can cut all numbers of teeth. Good thing, hobs aren't cheap.
Set up is not difficult. but it is often more time consuming than cutting the teeth if only one one a few
gears are to be made, as the machine is designed for manufacturing.
