    Default Torque multiplier?

    Need one that can get me to 325lbs or so. Need to be able to torque down the crank nut on my M30.

    Seems like an expensive item...anyone have suggestions on where I can get one for a reasonable amount of $$?

    Suppose I could check to see if this is a rentable item.

    thx

    Default Jeff, I've done this exercise before on my m30. Since I didn't want...

    to spend several hundred dollars on a torque wrench for a one-time-use, I decided to make one myself from a 6 ft cheater pipe and a hanging scale I purchased from the hardware store. I think I took a picture of this but need to find it. Was able to get 325 ft lb from this homemade setup.

    Default Picture of homemade torque wrench. m=>

    When you pull on the scale make sure that you make a right angle between the cheater bar and the imaginary line going through the length of the scale/your arm.

    Default Forgot to mention this scale has a weight...

    capacity of 55 lbs. So can torque up to 55 lb x 6 ft = 330 ft lb.
