    I'm abit unclear on torque measurment. Ft pounds and inch pounds. If you divide a inch pound number by 12 is that the foot pounds? A hyd motor I'm looking at puts out 1800 ft pounds----so times 12 is inch p ounds? Also, will running that motor thru a 3 to 1 gear reducer yield 5400 ft pounds torque, minus the normal loss due to friction, etc.? FB

    ...................12 inch pds. = 1 ft. pd. of torque
    ...................are you sure that hydraulic motor puts out 1200 ft. pounds . of torque?? Most large diesel engines in 18 wheelers don't exceed 1500 ft. pounds. .........1800 inch pounds \12 = 150 ft. pounds . This sounds more realistic to me . fordy.. :)

    12,000 dollar motor on a drill rotation head designed to rotate a drill string with a weight of 30,000 pounds and a depth of 1000 plus ft. Powered by a variable volume pump for speed control. FB aka Ozarks58 (different computer)
