Ok, i understand now why you get confused so easily
-
OP can either mean original post (text) or original poster (person)
-
Well, we wonder why...

Hi John, i also ordered your book last year, it's very good and practical. Thanks for the extra 55 hints!
-
true, i think you also tried the formula/spreadsheet on platetuning.org for predicting B1's and found it did not work very well. However, somehow B1- is affected bij the top and B1+ by the back wasn't it? (or v.v., i always forget) I think (like you also mentioned) they should be around the "right places" and perhaps not too weak or strong. My idea is that A0, CBR, B1- and B-1 just support the lower register and preferably not causing wolfyness. I think you mentioned every mode spreads around 5 semitones?
-
I think it is not about some absolute pitch, but rather a design parameter where the plate has reached a certain stiffness to weight ratio. When the plates are glued the M5-mode (taptone) will be gone anyway, but there seems to be a relation/correlation between M5 and B1-modes, which are more important.

I have wondered how resins and oils can be acidic, as acidity is defined by H+ ions in aqueous solution. I suppose it's because wood, resins, oils and even air always contain a few % moisture to allow acidic behaviour.

I have seen a few also. One was from a 3/4 with 5 mm thick top and some sort of ridge left in the wood that had to resemble a bass bar. It did not sound like a 3/4 Del Gesu funny enough, could have been the bass bar
-
Hi Doug, it's more about relative stiffness, so the stiffness with equal dimensions. Higher speed should also give higher stiffness. Would damping play a role in bows? Damping will decrease with age.
-
I missed that part Searching the archives i found a remark by Bruce Tai: that might be the problem for many of the treatments after short term success...
-
Thanks ctanzio, so the wood properties would not have changed that much in 100 years. I understand that a fungi treatment can speed up the hemicelluloses breakdown. Some years ago a violin from treated wood beat a Strad in a blind test. I don't know if makers here have experimented with that, but that one is on my todo list
-
Isn't speed of sound also a measure for stiffness? From wiki on speed of sound: I also thought wood gets more stiff when aging, so a Lucchi reading was probably not the same 100 years ago.

Just trim the sides a bit, it will be ok

i suspect he means sanding some varnish away .. a weak d string has been discussed before, here's one with some more ideas:
