I'm going to have a go at making a truss rod, based on the ones in the Koch and Cumpiano books (adjustable or one way twin rod system?). I have some 3/16" steel rods and other parts, but I need the right die that matches the truss rod nuts sold by various stores. Can anyone provide the correct details of die guage and standard to match a nut they know will fit? I've tried a 10-32 NF with an lmi rod, but it doesn't fit which is surprising but then again there are so many thread standards. lmi have stated that they do use a 10-32 die, but didn't specify the standard (waiting on their reply, hopefully they will reply...), as I said the die I have doesn't fit.
