So I've got Speedy Kollmann 1500 and his younger cousin Ridgid-Kollmann KM-1500 in the arsenal. Currently we rotate use on them, but I was thinking of swapping the motor out on Speedy to a larger hp. My thought was to make something with more beef than the 1500SP (more like the old K-500) and put a 2hp motor on it. Speedy still has the original motor on it from the 60's and I've noticed some reduction in power on longer runs lately (I'm usually 120'-160' out in 6" runs).
Any thoughts or suggestions?
Anyone (Mark or Ron) have any comparisons on function of the 500 and 1500 in terms of power and torque?
