Really? We went completly COTS by putting AM fischer-to-Cim planetery into a 3 stage AM stacker box with a single sprocket reduction on the output. This solution was quicker and easier than building a custom gearbox to get the same redction. The use of the planeteries also gave use a more compact footprint than we would have ever had with a spur gear based transmission.
