7603(?) Restoration


 

About a year or so ago, I found a website (possibly youtube video) where the guy performed an electric and mechanical restoration on a 7000 series scope (I think it was a 7603 but possibly 7613, 7623, 7633). The scope looked almost brand new and I would like to review that material if possible. Does this sound familiar to anyone here?

Thanks,
Barry - N4BUQ


 

Maybe you’re talking about Robin Renzetti:

I was thinking he painted the frame but now I see he sanded it down, bead-blasted it, and then applied a clear-coat (Permalac). Very clean look.

Thanks again,

Dang! If you scroll down from the bezel treatment, he used a pantograph engraver to make button text,
filled with epoxy, then filed and polished to look like new gambling dice!

Truly fine looking, but I think I'll just look.

My scopes don't get quite that perfect... but then, my old sports car is not restored to concours near perfection either...

Yeah Robin is not your average bear. He goes by "robrenz" on YouTube where
he's posted a bunch of machining related videos.


 

Yes. He certainly has some nice equipment to do that work. I wish I could do the same with my pushbuttons. I've seen the other methods but that looks the best by far.

It's better that way- then you can actually use/move/drive them without too much worry.
