I have the Little Giant AA-4 screw plate from Greenfield, which is a wood case with adjusting dies and matching taps. These adjusting dies cut from slightly oversize to hugely undersized threads, which is very convenient. Are similar kits still available? I would love to have different kits with the same kind of adjustment. The modern split adjusting dies suck because they only adjust by very little. This is my set. It only cuts number threads, plus 1/4x20. I am looking for a wider range of threads.
