[CAUT] lyre disassembly

[McNeilTom at aol.com]

Dear Fred, and Colleagues -
 
Thanks for the tip.  Good advice!
 
I'd like to add to that: (1) I seldom dismantle these joints anymore.  
Instead, I use a belt clamp around the entire lyre to pull it back together, 
encouraged by a few whacks with a rubber mallet.  This way you can get the joints as 
tight as they will ever get.  Then, with the belt clamp still in place, I use 
thin CA to 'remake' the glue joint.  I've done quite a few of these over the 
years and have never seen one fail again after this treatment.
 
(2)  Sometimes it is necessary to disassemble the lyre; say, when someone has 
attempted a repair already and botched it.  Then, instead of a reversed pipe 
clamp to push the lyre apart, I find it easier to use a bottle jack.  It is 
smooth and very powerful, but may occasionally 'unmake'  the mortise and tenon 
joint at the unexpected end of the upright member.  If so, perhaps that's just 
as well since that joint was probably a weak spot too.
