Cutting a gear on a lathe indexed off a smaller gear with the same number of teeth seems like a Very imprecise method of machining/manufacturing. Proper method of cutting gears is with a cutter called a hob. Mitsubishi also includes a very accurate gear cutting programming package in their wire EDM machines. You almost don't have to do any secondary gear tooth machining and finishing operations with the EDM gears.
We had a machine at FARMALL called a Shear-Speed gear former. Machine took a stack of gear blanks, already turned and center bore turned or broached. The machine had a specially ground cutter for each space between gear teeth. A cutter head held the cutter teeth, and the machine advanced the cutters about .001"/.002" into the gear blanks on each stroke. The gear teeth still needed finishing, normally "Shaving", oon a Red Ring Gear Shaver. We also had a bunch of small Barber-Coleman gear hobbers for small pump gears we machined from blanks supplied from West Pullman Plant. One machine ran one part number. We ran that machine when we needed that part number and it sat unused until we needed more.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
