    If your ft/lb one goes low enough but most don't. My lowest snap-on ft/lb one starts at 5ft/lb which is 60in/lb. Most measurements calling for in/lb are lower than that.

    yea, ur right. I just looked at it and it starts at 5. Is there any other way i can measure the preload of the pinion without at torque wrench?

    preload on your pinion should be a with a beam type torque wrench and I think spec is in ft-lbs on most... a click type is useless for measuring pinion preload.

    It is in/lb on the pinion. I just did it by feel as I only have a click type in/lb wrench. 12-14 in/lb is really just taking up all slack and then leaving it with a very light drag. Ideally see if you can rent/borrow a beam type wrench.

    feel what the drag is like before you tear it down and you will know what to feel for when putting it together. When you know what to feel for then getting the beam wrench out of the box is a waste of time.

    yes, a fish scale.... make sure it is accurate by hanging a known weight on it. should be easy enough to find one that is in ounces. now ya get to do the math. have to turn ounces into fractions of a Lbs, then turn that measurement into inches. not hard really. should also only cost about 5 bucks at walmart

    oh, make sure you pull in a STRAIGHT PLANE.

    the correct tool for the same use i described above is a pus pull gauge. they can be spendy though. hardest part about a fish scale is watching it to see the reading before it moves, the push pull gauge has a second needle that stays at the max.

    Or, a trigger pull guage like those sold by RCBS. They are probably more accurate than a fish scale, and they have a little pointer that holds the reading for ya. I think they run around $20 or so. After you set up your gears, you can go put hair triggers on yer favorite firearms. I couldnt believe the prices for dial in/lb torque wrenches. I managed to find one for cheap that will do up to 30 in/lb. I think it cost me $60 or so. If you want the brand I'll have to run downstairs.

    DOH! I wish I had found that one when I was looking, I got a dial type, cost more, but comes with a nice blow-molded case with tight fitting foam inside, and it comes with a calibration spec sheet.
