Nicely done. I just wrapped some electrical tape around a steel nut driver on a recent Philco 60 alignment. While it prevented shorts to the chassis (some of those trimmers are hot!), the metal did affect the capacitance a bit. I compensated by tweaking the trimmer past the peak and checked the result one the tool was removed. It would certainly be easier with a non-conductive tool like you made
