Re: Tiple Trouble...
You can probably acquire a replacement tiple bridge from C F Martin Co. I re-bridged a Regal tiple with a Martin bridge, and my Regal taropatch (8-string ukulele) has a Martin tiple bridge -- no doubt a replacement -- as well. The taropatch was re-bridged before I bought it.
Odd anecdote about the Regal tiple: the instrument had the standard tiple 2-3-3-2 string spacing at the nut, but originally had a pin bridge with five bridge pins, each of which was supposed to anchor two strings. So the string spacing was 2-3-3-2 at one end of the fingerboard, but 2-2-2-2-2 at the other end. Recipe for chaos. I tried for about a month to play it with that configuration, then gave up and had the Martin bridge, with 2-3-3-2 spacing, installed instead.
Concur with Charley's opinion: ten steel strings produce a lot of tension. I'd get the job done professionally. You have a unique instrument there.
