polishing adjustment screws

Postby va3sax » Thu Feb 25, 2010 12:54 am

I just bought a new(for me) bug from another ham. unforunately it's seen better days and all the parts are quite rusted. I was wondering if any of the key restorers on here have tips for making the it shine again; particularly the adjustment screws so that they move properly.

Screws are the hardest parts to polish. I do mine with a dremel tool and a wire wheel. Then I take them to the bench buffing wheel and polish them with a loose leaf buff using a non-cutting buffing compound. Don't have a buffing wheel? You can do it the hard way, just get some good metal polish like Flitz or if you can find it, Blue Magic. That is the best! Polish the threads with an old towel, something that has some matt to it, to get between the threads.

OM Santa brought me a vibratory tumbler and I plan to use that to polish my screws and small parts from now on. The media is crushed corncob with Flitz tumbling media additive. Hopefully, this will cut down on some of my polishing time. My last key had over 200 hours polishing time. That ain't right, hi.

If your new old bug is valuable, you might consider getting the book by WR Smith on restoring bugs. It is a great book, packed with lots of great stuff on restoring keys. I just wish I had gotten the book 5 years ago. Good luck, if I can be of any help, let me know..

Thanks Bill
Grabbed a tube of flitz and started to polish the arm. It's working wonders on the brass. also got started on one of the screws. they're a little bit more challenging getting in between the threads but none the less I can definitely see the oxide coming off.
