OK, time to get on with pre-assembly.
I am using a Bakelite pickguard and will have to lengthen the neck pocket opening to account for the neck being so much further into the body. This one came out OK but it's a little to sloppy so there will be another. (maybe red tortoise shell)

The next step is to locate the bridge at the right distance to reach the 30" scale. It must also be properly centered so the strings are spaced evenly on the fretboard. Must find the center line.
Before I took the Bronco apart it took the critical measurements from the front of the nut to the bridge saddles. I transferred those to the blue tape.

I am stringing fishing line to get the bridge in just the right spot. Once I mark the spots on the tape I can drill pilot holes for the mounting screws.

The Musicmaster bridge is a string through body design and not having a drill press makes getting the holes evenly spaced on the back a little more difficult. To get them close I used Rhomcos trick and drilled 1 and 4 string holes all the way through. The hole for the 2nd and 3rd string was only drilled a 1/2 inch deep from the top. I flipped the body over and used the bridge as a template and marked and drilled the 2nd and 3rd string centers based on where 1 and 4 emerged. When I open up the holes in the back the 2nd and 3rd string holes in the back will meet the ones from the front and the pattern in the back will be as evenly spaced as I can make it.
I counterbored the holes in the back to uniform depth to use some long bass ferules I found. The short ones came with the musicmaster bridge.

Drilling that hole for the bridge ground wire was a nail biter. A footlong bit and I made it just to the bottom of the control cavity without hitting any of the screw holes. I thought about going to the cavity via the endpin and the dropping a hole to it from under the bridge and them plugging the endpin hole. In the end I just did the hole straight from the bridge.

Now I have the bridge installed and I can string this thing up to work on the Pickup location and angle. This is also the first chance to get a feel for it and I like it. The shorty feels great. Low string tension and easy spacing between positions. The tone was lively and it intonated just fine so the bridge location is right. I did have to use a neck shim to raise the neck a little so the bridge saddles were not bottomed out.

...........Next is finishing the body and I can tell the sealer that is on this cheap imported body is going to be tough to sand out.
