> Is a Robertson bit a square drive bit?  If so, maybe there's some steel square bar stock that will fit.  Just bend a 90 degree elbow into it, like an Allen (hex) wrench.  Or a woodworking store might have square drivers.  Maybe even Sears?  Or take an old screwdriver or other useless or broken tool that has a shank large enough and file a square end on it.  --Dave Nereson, RPT
