 I agree The cold glue is compatible with old hide. I think it reactivates it 
and melds with it.
  I think the reason for the failure rate of tightbond over old hide  as you 
say Joe is this,  when  tightbond is applied over old hide glue  the 
tightbond will not stick to the old hide. The whole thing will however turn 
to a mess and then the tightbond and the hide glue scrapes off easily in one 
gooie convoluted mix. WHich is a good way to get old hide glue to scrape off 
easily. Once clean use whatever glue you wish.
  But I don't think this mixing of glues would make for a strong glue joint 
at all.  JMHO
