          Hi Paul
           I've used about four quarts over the last year or so  in various 
applications. It is in my opinion a much tougher glue than the average yellow 
wood glues like tightbond. I first used for gluing bridge caps for its non- 
clog the drillbit benifit. I've since found it to be almost non- thermo 
plastic, which is good in certain uses. O.K. add enough heat and every thing 
is but I mean if you put something together with this glue be sure you don't 
have to take it apart. I recently glued a soundboard in to the rim and  the 
next day the glue was hard as glass and the board boomed nicely. With my 
usual cold hide glue apllication I usually don't get a good solid boom for 5 
to seven days.        
   However being a believer in using the right glue for a given application I 
would feel sorry for any one who has remove this glue from an inner rim 
(rasten) without tearing  up the glue joint. It's just very tough stuff. So 
be warned. I don't know if I'll do that again.
     Rib joints and board work would be another place that would be fine. I 
mean you don't want the ribs to come off.
