Since that failure on an early guitar I have made several from cocobolo and have not had an issue. I always make sure the gluing surfaces are freshly prepared and glue up within 15 mins. If I can't glue up for some reason then I prepare the surfaces again prior to glue up.
For the back join, I shoot the two surfaces with a hand plane and then immediately join using ca. 10 mins later I scrape the back on a flat board where the re-enforcing strip will go and immediately glue the strip onto the back with hhg in my go bar deck. The following day I scrape where the braces will fit and straight away glue on the braces, again with hhg in the go bar deck.
For the linings and neck and tail block, again I scrape prior to glue up, but this time I use fish glue (gives me more open time). I also glue the back to the rims using fish glue after scraping.

Re: Gluing Cocobollo
Thanks bob, that guitar looks very sweet. Maybe I'll try it your way, I don't have fish glue but I could check it out. I guess I'll also do some testing as best as I can. The Cocobolo I have seems to be twice as heavy as a set sides of IRW. This will be for #6, Also I put a scap pc. next to a light bulb and the oil that came out shocked me. I can't wait to hear this stuff, it taps like glass...very cool stuff. I can see how people get sick from this stuff, it's different than any wood I've worked with. Thanks again...
