Re: [Harp-L] Manji welded reeds?
Hey, we've all gotten used to technical advances in electronics giving
us high performance gizmos for ever cheaper prices. If you could get a
cell phone in 1970, what do you suppose it would have cost?
If Suzuki can reverse the trend of ever more expensive high performance
harps and come up with a harp aimed at the mass market that comes close
to the performance of custom models, then I could get used to the idea
of a cheap, disposable harp. Back in the 70's this is how I thought of
the Marine Band.. If they had customizers back then I was not aware of it.
I hope this is what they've done and eagerly await their availability at
the usual harp outlets. The market will decide.

Subject: RE: [Harp-L] Manji welded reeds?
I'm a relative newbie to harp-playing and I know it's probably a dumb
question, but.......if welded reeds are such a tremendous improvement
over rivetted reeds, wouldn't replacing a welded reed with a
screw-fastened reed result in a poorer quality harmonica?
If not, then why not use all screw-fastened or bolted reeds in the
first place, rather than welded reeds?
Spot-welding is much more amenable to an automated assembly process
than rivets or screws. (See those videos on assembly of automobile
bodies.) One suspects that this is the most important reason for
choosing spot-welding. Better alignment and closer tolerances are
real but marginal advantages to the user. Field-replacement
difficulties are challenging but not unsurmountable. Replacement of
rivetted reeds is also a challenge to the average harper.
And if indeed the performance of a welded reed is so vital to the
musician at the outset, why would he/she then settle for a lesser
harmonica with a repaired reed which doesn't meet original
manufacturer's specifications? I'm thinking that if welded reeds were
so vitally important to the professional player in the first place,
he/she would simply dispose of the damaged harp and buy a new one,
rather than play an "inferior" instrument.
.....Or am I missing something? Jim,
Quite the contrary.
As they say in talk radio; "you stole my thunder."
And, with those close tolerances, how could a lowly human easily
align this replacement reed in the slot? What about all of the
distortion and stress put on the reed and the plate when the holes
are drilled and threads are cut?
Valid questions. Because you drill the hole in the reed bigger than
the screw, you can always loosen the screw and change the angle and
offset of the reed with respect to the slot. Although this can
involve quite a bit of fiddling around, it is theoretically possible
to get a perfect alignment. I have found that it helps to put a
lubricated washer under the screw head to reduce the tendency of the
reed to move as the screw is tightened. You still need a drill press.
Because welding is fairly new, harp techs haven't had much opportunity
to work out solutions to the problems that you have correctly
identified. However, we're working on it. Stay tuned.
