Lots of pictures tonight, so please bear with me.
Got some work done on the headlight bucket. Some good, some bad, but it's progress one way or another.
The first hurdle was to get the mounting screw holes drilled correctly. As you can see below, I fitted the headlight rim on and marked lines with a sharpie to get the position marked:
After that, I removed the headlight and replaced the ring so that I could see where the mounting tabs were. A side note here is that you'll notice that it's pretty rusty in there. Mainly, it is surface rust that I'm not that concerned about. I'll probably sand it down a bit and coat it for protection. However, you can see that the adjustment screw spring is short - that's because it just fell apart when I touched it. That will need to be replaced, at least:
This allowed me to mark were the holes should be and to drill some tiny pilot holes. Like many brilliant thoughts of mine, this worked about as I could expect...which is to say not well at all. The holes were slightly off, but I was able to widen them a bit and get the screws to mate up:
Now, the bottom looks great, but the top (once everything was tightened down and pulled together) the top turns out to be way off (about an 1/8th of an inch.)
I have three options here. 1.) I can live with it, but it will bother the heck out of me 2.) try to find another headlight (I know a '71 350 should work perfectly) or 3.) get my glass 'n Bondo skills out and reform the top of the bucket. Three is most likely right now, unless another light plops in my lap.
Putting that aside for the moment, I still needed to get the pivot/mount holes for the bucket itself drilled. It is deceptively hard to measure out equal placement of holes on a small flat strip in a sea of curved surfaces. Here was my solution:
First, I traced out the shape of the mount surface on the side of the bucket. I cut this shape out and folded it in half to find the dead center of it:
Then, I placed this on the old bucket to see how far down to make the hole.
From there, it was a simple matter of poking a hole and then marking this hole on the bucket to drill.
The surface pitting around the hole can be touched up before I paint it. At this point, there was nothing keeping me from mounting it up and seeing how it looked:
