Back in the day many steel players hacked up their Stringmaster to make them into "pedal steel guitars". The two necks Bill sold me had suffered such a fate.
This is the easy neck. It's a July 1955 22.5" scale neck that is a #2 size neck. It would not have originally had an output jack. As it did not have leg socket holes it must have been part of a T8 or Quad when it left the Fender factory.
Here's what I did with the better of the two necks I bought.

The top side was in good shape. The bottom side is a different story:


The number of holes in the back was astounding!
I set about patching & plugging all the holes:

The output jack hole was too big so I doweled it and filled the connecting rod holes:


Once the glued dowels had dried, I trimmed them flush and patched the big gouges. I routed out a channel and then glued in a piece of poplar. Then I used the router to trim the patch flush. Next was filling the other gouges with wood filler and sanding it all flush.

The jack hole was drilled out to 5/8"
I used Krylon Gloss Blue Ocean Breeze (5506) for the color. It took 4 coats to get everything covered evenly.
I bought a set of original Stringmaster pickups. Bridge Stringmaster pickup read 8.58K North, Neck Stringmaster read 8.77k South. Yes, it has the blend pot & wheel under the cover. Wired just like it was in 1955. The other parts took a while to track down.

As a side project I made a flat table with adjustable legs to set the neck on when I play it.
I have set it up in A6 tuning:

Thanks to all the members who helped me find parts!!!!
I did mention that I bought TWO necks from Bill. Here's sneak peak at the hard one:


Stay tuned!!!
