Re: Shifting or Non-Shifting
Andymark. 1-speed toughboxes and 2-speed AM Shifters/SuperShifters. The best thing now.
In the Pre-AM days, we used to use DeWalt gearboxes (3-speed servo shifted), and prior to that we built custom 2-speed and 4-speed mesh shifting gearboxes. However, an AM shifter or SuperShifter is better than the DeWalts because it shifts more reliably (the DeWalts won't shift under very heavy load), and easier to manufacture (you make nothing, unless you are reducing weight).
Our custom 4-speed took quite a lot of manufacturing resources (we cut a bunch of gears from pinion stock, welded some together, made 5 shafts per transmission, and machined side plates).
