  1. Huh ??? The guitar in my pic is an archtop (sometimes called "cello" ) guitar with a cantilevered fretboard ( or "fingerboard" if you prefer) extension. All guitars have "heels" , but only archtop guitars have an "overstand". Flat-top guitars have the fretboard/fingerboard glued to the soundboard in almost all cases, with the exception of Dana Bourgeois guitars , and possibly some others, where the extension is secured to the soundboard by concealed bolts.
  2. Reason I asked was because this Hofner President archtop has arrived in the shop, and the owner wants the glaringly visible previous hack repair of the broken neck rendered as inconspicuous as possible. For the life of me I couldn't recollect the correct term for "overstand" ... thanks to Vda and everybody else for their contributions.
  3. Did she point that out? I must have missed that ... and now it's getting complicated, with two other multilingual terms up for consideration. How about I just call it the ""neck gap" ? ....
  4. Aaahh ... you minx ! Thanks for the clue ... got it now !
  5. Having a bit of a senior moment ... I have forgotten the technical name by which you refer to the distance between the top of the soundboard and the underside of the fingerboard ... it's something like "offset" or "upstand" or something like that ... a quick Google search didn't help ... memory refreshment much appreciated ... TIA.
  6. I was astonished to read that Stradivarius did not employ a mortise construction of any type, simply using a butt joint.. Are any of the Strads which are played today by concert artists still held together with glue and nails, or have they been reworked to a mortise and tenon construction?
  7. Thanks to all responders ... I do get that a "perfectly fitting" joint in a violin neck joint is not the same thing as having the parts mate as tightly as humanly possible, and that glue enters into the equation. But if the joint were to be made as tight as possible, then would I be correct in thinking that the flare of the neck and the corresponding flare in the mortise would be sufficient to withstand the string tension, at least for a short period ? I mean, the neck wouldn't suddenly fly off during the tuning process, would it? Carl seems to think so, unequivocally, so does everybody else concur?
  8. I am just curious to know if a perfectly fitted violin neck joint, prior to gluing, would withstand the tension of the instrument being strung up to pitch. I appreciate that this is probably not a common practice, but has anybody ever done it, even out of curiosity ?
  9. I did put this question to the poster on the forum to which I referred, (using your quoted post verbatim) but have had no reply. Whenever i see anybody declaim airily on an internet forum "I have seen many ...(whatever it might be) " I always feel my BS meter stirring. In this instance I believe it was calibrated correctly. It has however sparked a most interesting discussion on here, thank y'all.
  10. Bit of a weird question, I know, but on another forum somebody claims to have seen "many" violin tops collapse as a result of the violin not having a soundpost.. My main question is, does this claim sound realistic ? Has any repair person on here witnessed "many" tops collapse as a result of the instrument not having a soundpost? I would have thought it an extremely rare occurrence for a violin to be missing a soundpost in the first place, but hey, I could be wrong. That leads me on to question #2 which is : if a violin were to have the soundpost removed, and left in that condition, would the top in fact collapse at all, and if it would, how long would it take to collapse under string pressure ? Would the pressure alone be sufficient to collapse the top (assuming that that would in fact happen) or would the instrument have to be played extensively minus the soundpost for this to occur? I am sceptical that any violinist would continue playing an instrument without a soundpost, but maybe stranger things have happened .
  11. Ah yes, the notorious "glue-starved joint" ... glue starvation from excessive clamping pressure can only happen when epoxy is the adhesive of choice. When using other glues, be they protein based, PVA, or polyurethane, it is impossible to cause glue starvation by excessive clamping pressure. If any joint fails due to a paucity of glue when using anything except epoxy, all it means is that insufficient glue was applied in the first place.
  12. A really sharp business man will charge people to see it and to hear it ...
  13. reviving this slightly zombie-ish thread to paste a recent quote from another forum Does anybody do this nowadays ? I wouldn't have thought that the humidity exchange would have been slowed down by much , if at all. On the plus side, of course, the gelatine wash would have been totally compatible with any subsequent repair which might have been required.
  14. I can still recall vividly the horror and disbelief i experienced years ago when I lent my (freshly re-strung) guitar to an acquaintance to play one song, and when he handed it back, the two plain treble strings were totally black for the first few inches, and sounded absolutely dead.
