<p>I've never actually had problems, it's just that I've never used it - I'm put off by the short open time and having to keep the temperature up. My friend who trained under Rolf Eichinger in Granada for two years uses nothing else, but he employs techniques which don't appeal to me, such as using a flaming torch soaked in methylated spirits to resoften the glue in clamped joints and preheating surfaces using blocks of hot wood prior to applying the glue and bringing the joint together.

<p> Jim, can I ask why you came here and asked for expert opinions on this and then ignored all advice? It makes absolutely no sense and seems a waste of everyone's time. This is the kind of stuff that happens on Mandolincafe, not here. </p>

<p>As it turned out, I ended up using Smith's All-Wood Epoxy - for the peones, the back linings and for attaching the back. The end result is rock-solid (much stronger than any joint I've made with Titebond), and it wasn't as daunting a task as I'd anticipated. For the bindings and purflings I'll use Titebond. Regarding padauk, I've made two instruments with this wood in the past and used Titebond 1 without any problems.</p>

<p>I always wipe Coco with lacquer thinners before glueing and haven't had a failure, even with bridges. Amazing how much oil comes off on the towel.</p>

<p>I have found with Cocobolo and woods like padauk for the best results are to glue right after jointing the edge. If you allow it to sit for a day or two there can be glue failure. I think that letting it sit gives time for oils or resins to creep to the surface. Thats just my guess. With paduak the joint will darken after a couple of days and it won't glue as well. I use regular titebond for these woods..</p>

<p>Coco is the one and only wood for which I HAVE to use a mask. I find the dust extremely irritating, causing marked throat irritation and sneezing unless I do. As you say, it's a beautiful looking wood, and I think using it is worth the drawbacks. Thanks for your input on the Titebond.</p>
