S & S capo bars, zings, etc.

* Uh oh, this is starting to look like a budding career in advertising.

* Yep, but I understood the contention to be that hardening the V bar would
help the duplex zingers. Was that not right?

* I don't know. Cast iron is crystalline and not terribly malleable. Does it
work harden? I haven't a clue, it never came up before, but I would guess not.

* Sure. Mark Bolsius reported in a post that Ron Overs had added a small
pressure bar to shorten a noisy front duplex and it worked great. The last
two grands I strung got the "tuned" front duplex replaced with appropriately
sized and positioned brass half-round bars to get a 20 degree +
(thereabouts) draft angle and the shortest practical duplex length and it
seems to have worked just fine. I'll know more about this last one when I
get the dampers on and the action done. There's not a scrap of felt anywhere
on the plate at this point and I'm curious to see if anything makes unwanted
noises when it's all together. I'll let you know what comes of it.

Now Ed, you know they couldn't possibly be in heaven, so I'll probably run
into them somewhere else.
