While your suggestion is good for many boatanchor relays,

Hardly worth the effort, considering you can buy
one for a few bucks that has gold contacts and is
specifically designed for comm work.

Hi David,

I agree, it is best to replace, if a replacement is available.
When I use a hacksaw blade, I grind it to whatever thickness and
width I need. I typically grind to about 0.010 thick. (which takes
so little time on a bench grinder that you have to be careful)

In any case, the big point I was trying to make, is never, ever
use abrasive paper to clean up the contacts on anything. It will
cause the contacts to arc and burn from that point forward.

The good ole' style contact burnishers are still available. See:

You can Google up a search for contact burnishers and find many
examples. These are a MUST for old boat anchor equipment!

73, Roger
