Good advice blur911 / safristi. I will try to figure something out re. the pressure system and keep the psi to a mnimum. I wish I had done some more research before buying the torque wrench as my decision would have been different. So far it appears that there is a loyal following out there with respect to the beam type. I gather that they can take more abuse and do not fall out of calibration as easily as some of the other types. The only minor issue I have heard about is that the needle can sometimes not return back to zero. I think it would not be an issue to have it reset back to zero? I am not sure if this is something that can be done by anyone or if you have to have it sent in? Supposedly even if one were to heat it in an oven or conversly freeze it in a freezer it would still not be off by more than approx. 5%.
I have so far discovered the Warren & Brown Deflecting Beam torque wrench and the Sturtevant Richmont M Series Flat Beam models. I do not know if Snap On or anyone ealse (preferably a Canadian company) makes the beam types. I believe both are probably excellent products, both the W & B and the SR, if one does not mind the price. Sometimes you just have to pay the piper. I am still trying to find something similar but more local or at least find a local vendor selling these name brands. I sure would like to find something soon though, I hate to guesstimate these things. If anyone can recommend a good beam type being sold locally (Ontario - Canada) it would be appreciated.
Sears has decent ones. Lifetime warranty too.
