Dave, I heard stories of implosion from other people.  At least one of them was from a mail order dulcimer kit that was a bit notorious for having incomprehensible instructions.  I think that kit maker is no longer in the business.  

I learned my woodworking techniques from watching Tim The Tool Man Allen on "Tool Time", so I will never try building an HD.  Besides, the string tension of six D'Addario XLs on a guitar is a bit over 103 pounds…and that is just six strings. A fifth-tuned or octave bass HD will far exceed that.

A friend of ours had a slightly different disaster.  The pinblock joints on both sides separated, the pinblocks  twisted upwards and then broke free. This resulted in two pinblocks and a tangle of wire on top of the now-floating soundboard.

Now, I've never seen an entirely new instrument strung up with new wire, so I suspect that they may have a brief period of going slightly flat as the wire all stretches, but this was far beyond that.  He kept tuning it back up.  Then the soundboard abruptly imploded.  I happened to be looking on at that moment, & it was quite an amazing sight.
