Philco 118 tuning gang short at max capacitance
#2

Look to see if there are any outside rotor plates that somehow got bent in to create your short. Don't be afraid to bend the outside plates- that's why they have slits cut in them. After that-

On the back of nearly every tuning cap rotor is an adjustment screw with locking nut that adjusts the axis depth. It's rare that this needs adjustment and it is only used when there is a large dial tracking error in the middle of the dial.

You can usually see that the rotor and stator plates are not centered (evenly spaced) and if they aren't, this adjustment needs to be made. It will often eliminate shorts at max.C.

If you have a capacitance meter, disconnect any wires going to the stator and adjust the rotor axis screw for minimum capacitance when in full mesh.

After doing this adjustment all alignments in the procedure after the IF must be done over.
