I made a tool for this from a 1" diameter knurled, round aluminum nut.  The center hole is large enough for the capstan screw head to just fit inside it.  A hole was drill from side to side through the nut, with a large gauge of piano wire inserted in the hole, and bent over on each end..  The nut is placed over the screw, and rotated until the wire drops into the screw slot.  It then becomes a 1" diameter knob to turn the screw with.

"Does anyone know if these tools are still made?" 

  

"I use this one for adjusting rocker capstan screws as below."

  

AF,

Yes, they are. Made by Stanley. Available at Ace Hardware Stores. There is also Phillips version.

HOWEVER,....it is not the tool to use for Rocker Capstans, IMO. There is available from Renner a very good off-screwdriver that is far more efficient and exacting. As it is a duplicate of the original one used in factories, it actually WORKS!<G>

The problem of the ratchet types, is that you cannot get the tactile feel that is needed to accurately adjust rocker capstans.

I do use the ratchet off-set thingee for extracting upright spring rails. They're pretty good for that sort of thing.<G>
