I can't quite understand what's being demoed here but I think it's a new servo that will do 50 RPM without a reducer.  I don't think it's specific to the machine even though they're flipping a switch near the needle. I think it's just added there. It's a Hightex/Cowboy product so maybe @CowboyBob can fill us in?  I wonder how the low speed torque would be?
