WE WIN; THE BRIDGE WORKS LIKE A CHARM WITH THE VIBRATO ! The tape and it's glue is just resilient enough to allow the bridge to rock a very small amount and thus not cause a conflict between the vibrato and the bridge pinching the strings. I anticipate it will work even better once dry lubricant is put into the string slots. However, as the tape dries out over time (probably a long time), the alterations of this bridge's slots (or another modern same type replacement bridge's slots to preserve the original bridge) might be required as said on page 18 (Saddle Slots Angles) .
Lubing the saddle slots was not done at this point because installing the strings ground wire was next and any stray lube could cause a problem for the ground wire camouflage paint sticking. The saddle slots will be lubed when the ground camouflaging is done and dried.
The ground wire installation and camouflaging is shown on the next page.
~ A note about the vibrato arm worthy of mention ~
The vertical height on the hand end of the original vibrato arm doesn't have ample throw before meeting with the pickguard; ie. No dive bombing whammy with the arm in it's original shape. I feel sure this was deliberately designed in to reduce the amount of vibrato action with this bridge. It is worthy to make mention that when all of the shortcomings of this bridge and vibrato are worked out, ....an UPWARD curve can be bent into the vibrato arm between the brackets #1 shown below, to give the vibrato arm more throw. In doing so the hand end can be returned to a flatter angle like it is now by bending a DOWNWARD curve where shown at bracket #2. When / if bending the arm, the screw hole area should be clamped into a vice using wood shims to protect the vibrato arm; Which will prevent the flat surface for the screw and it's washers from becoming bent in the process; The screw and it's washers must have a that flat surface to mount upon.
