Stephen, The type to use is one that is measuring INCH pounds. The one I have came from Sears, #44644. As this was purchased years ago, it may be under a different number, or not even available. The supply houses have them also, but I don't care for the design. The best answer for these type of questions is: Get all of the supply catalogues. AND, read them, thoroughly, don't just browse. You'd be amazed at all the things available. BTW, there are many items that are not even in the catalogues, but the supply houses have on request. So, make a few phone calls and get to know them.
