Drivers Needed...
The GS-4 uses Boxpoc drivers. At the time, the only source I could find was from "Little Engines". These drivers were very well made but were not exactly like the GS-4. Oh well! This was my first attempt at machining cast iron. I burnt quite a few brain cells trying to figure out where/how to start machining them. I looked at several articles and decided it's time to bite the bullet. The centers were drilled, bored and then reamed. I then mounted them in the lathe and began cutting.
I did the backside first, then turned them around and did the front. I saved the tire and flanges for last. I must be lucky because everything turned out fine. I also had to make "custom" cutters for my lathe to get the proper profile (another learning experience). After completing all 8 of them, it was time to look at my work and be amazed I didn't screw up.
