For the most part nobody uses lacquer or will even paint an old car anymore. I'm pretty well versed with what goes into painting stuff. I've restored a car and did all of the body work and prep and most of the paint. My brother has been building and painting guitars for years, I have a buddy who owned auto body shop and also painted Harleys and another friend who still shoots paint on his own bikes. These are old guys that I've known for decades. It's hard tedious work (especially the wet and color sanding) and anybody who does it for a living is crazy in my book.
A project like this is just something to play with and part of the fun is seeing what I can get away with and later you'll see just how far I push that.
Anyhow, back to this silly little thing.
This is the outside bottom of the mounts altitude tanget arm
It's really just to show it's condition and what the nut and screw is suppose to look like.
Between the two set screws a pivot point is created for the slow motion collar adjuster.
The adjuster on the inner side was broken off at the nut so I filled its end flat and cut a slot in it.
It's the shorter one (left and below) the long one, and they are the those old obsolete threads.
I could have made a new one with a nut, but didn't want to cut new threads in the arm
The two little set screws (bottom right) are ones I made for the finder from brass 6-32 screws.
This is the inner side. A lock nut is not completely necessary plus it won't show.
Once I get the mount adjusted I can always put a dab of paint on the screw if it wants to move.
BTW, these little adjusters probably break quite often.
On badbacks scope I noticed they were broken on both sides.
The left lower back finder adjuster was frozen and snapped off while trying to remove it.
I was able to drill it out without damaging the threads and used the good one from the top in it's place.
The one on the right side stayed in place making the two bottom ones match.
I then replaced the top one with a slightly different thumbscrew from another finder.
The back adjusters are brass but the front little set screws were steel and rusted in place.
I was able to get the top one out and reuse it, but the bottom two had to be drilled out.
Their holes were re-tapped for 6-32 threads and I made the two new screws (shown above) to fit.
I slightly rounded their points and did the same to the surviving top screw.
Which IMO had a way too sharp and damaging point.
.
Just another shot of the finder mount.
Early on I had done some quick test touch ups, but it needs readdressing.
Between the back adjusters you can also see more evidence of that disturbing bubbling corrosion.
