| Your best course of action would be to go out and buy an inch pound torque wrench. I'm not sure if you can convert foot pounds to inch pounds or not, but you certainly wouldn't divide by 12; I believe you would multipy by 12. So, 5 foot pounds x 12 inch pounds per ft. lb. would equal 60 inch pounds. |

... and where does one buy one of these - other than Sinclair and Brownells, that both sell some pretty expensive models?? Is there nothing "cheap and cheerful" out there that will do the trick? - mike |

| Look on e-bay.. Search torque wrenches.. I just bought one for this very purpose and it works great. It went for about $30.00 hope this helps, Doc Stone |

| You had the conversion number correct (multiply or divide by 12) and the correct conversion was previously mentioned.
Just wanted to add, that in the aviation field, the practice is to NOT use a torque wrench within 10% of it's upper and lower range.
Basically if your ft/lb torque wrench is a large 1/2 drive capable of several hundred ft/lbs of torque, it may not be all that accurate at a mere 65in/lbs. The lower torque ranges are best served by a 1/4 inch drive torque wrench.
Torque wrench accuracy can be affected by poor handling of the tool. In our hanger we test each torque wrench on a calibrated torque wrench tester prior to every use on an aircraft. Usually they are close (if not dropped or overtorqued in the 'reverse' mode) but they rarely are exactly correct. But, at least you'll get consistent results even of off by a few in/lbs. |

| I learned all about this the hard way with my Sako 75SS. I used the Remington spec. to tighten my action screws and really screwed things up! After tightening my action screws to 65 in/lbs I went to the range only to find bullets flying every direction! I backed my action screws down to about 30 in/lbs on the FWD screw and 20 or 25 in/lbs on the tang screw and regained 1/2 - 3/4" accuracy. I really don't know if 65 in/lbs is really required personaly I don't think it is I wouldn't use 65 in/lbs again. |
