I have a Craftsman FT/LB 1/2" drive torque wrench that's probably 8 years old or so. I might as well get it calibrated, but in any event it only goes down to 20 FT/LB. This has been fine for all of my car tinkering over the years (I subscribe to the idea of "Use torque appropriate to the size of the fastener", as well as the idea of using a 1/4" ratchet where appropriate so as not to over-torque the small stuff), but since I'm likely on the verge of tearing my R65 completely apart I thought I might start with a new smaller-drive torque wrench. So, in your opinion, would it be better to get an IN/LB model or a FT/LB model that goes down to, say, 5 FT/LB? And further, 1/4" or 3/8" drive? Thanks!
