[Amps] turns counter

[Steve Flood]

Having been shocked by the price of turns counters, I found some fairly inexpensive Veeder-Root units on ebay but they lack the hardware needed to join them up with a panel-mount shaft (for the tuning and loading caps).  I bought a couple anyway figuring it would be easy enough to homebrew something with a pair of miter gears.   However, after a few hours on the web searching, I still could not locate a proper set of gears.  Rather than waste more time, has anyone been down this path before and can offer suggestions?   Thanks,
