Re: [Hornlist] Solder or Epoxy?

[Joshua Cheuvront]

Thanks everyone for the advice!  I ended up using epoxy to put on three 
beautiful mercury head silver dimes.  This morning while I was at my 
parents' house, I happened to mention to my mother that I was going to glue 
dimes onto my valve spatulas.  She left for a few minutes and came back with 
a large shoebox completely filled with her old coin collection from when she 
was young.  What luck!

I've done this a couple of ways.  One way is to make a bracket to extend 
and/or raise the keys from the original bracket soldered to the valve 
casings.  The lower portion of the key mechanisms will probably need to be 
re bent to position the spatulas where you want them and still operate the 
rotor strings.  Anneal the part of the key you are going to bend.  If you 
don't have a torch, get them red hot on the stove.  Plan the bends both 
before and after you've moved the keys.

The other way is to make a set of longer spatulas.  Hobby shops carry brass 
strip in fairly thick pieces.  Cut and shape the strips to cover the old 
spatulas and shape them to be attractive and unobtrusive.  A one inch belt 
sander makes quick work of the shaping, and is one tool you'll always be 
glad to own.  A sanding disk in an electric drill works, too.

Soldering is the easiest way to attach them, and is easily scraped off if 
you want to switch back.

For epoxy, I recommend the five minute variety sand the mating surfaces with 
220 grit.  Five minute epoxy easily comes apart with steam or boiling.  The 
spatulas can be polished with fine grades of wet/dry sand paper followed by 
scotch brite and brass polish.
