davewyo Posted July 15, 2015 Report Share Posted July 15, 2015 I'm currently working on a gift box made of Bocote. The wood data base indicates that gluing is usually not problematic. I am okay with that, and I was going to use TiteBond III, but while cutting the miters I feel like there may be some level of "oily-ness" beyond other exotics I have used (specifically katalox and chechen, and some thin inlays of Paduak, Purpleheart, Yellowheart, and Wenge). From your experience with Bocote, does it glue up with no problems? I have mitered corners and I will be putting "keys" into the box for reinforcement. If you think epoxy would be wise: For such a small project can I use an immediately available Devcon 20 min. epoxy or is there a significant difference between hardware store two-part epoxies and something like West Systems? Should I wipe with Naptha or Lacquer Thinner, or something like that, immediately prior to assembly? I have never glued up a project with epoxy. Is the squeeze out a nightmare (to be avoided at all costs), or can I clean it up without undue effort? Quote Link to comment Share on other sites More sharing options...
bob493 Posted July 15, 2015 Report Share Posted July 15, 2015 For exotics, I typically use polyurethane or epoxy. titebond doesn't cut it ( i dont want to hear about random success stories with titebond, its just not the best option). 20 minute epoxy is for hobby repairs, not gluing up wood. You want long cure, the longer the better actually. 24hour west systems or zpoxy works best from the things I've tried. Cheaper epoxies just don't work well, and have next to no shear strength. Wiping with acetone and a paper towel is a good idea to get rid of the surface oils, be quick in your process. 1 Quote Link to comment Share on other sites More sharing options...
Boatworks Today Posted July 15, 2015 Report Share Posted July 15, 2015 Wiping with acetone and a paper towel is a good idea to get rid of the surface oils, be quick in your process. That's the key right there. Clean mating surfaces well and most glues will work just fine. 1 Quote Link to comment Share on other sites More sharing options...

davewyo Posted July 15, 2015 Author Report Share Posted July 15, 2015 Thanks for the replies. When you wipe with acetone do you glue immediately or do you wait for the solvent to dry? Would something like this System 3 work well, or how about West Systems 610 I would prefer something that is not too expensive and can be used on multiple projects with storage time in between. If these are inappropriate, what do you suggest? Quote Link to comment Share on other sites More sharing options...
Trip Posted July 15, 2015 Report Share Posted July 15, 2015 WS 6-10 isn’t really the right tool for the job – it’s more like a marine construction adhesive. Good product, but not for this... For most exotics, a wipe with acetone (or similar) is key. I wipe it down just prior to application, no wipe and store – just wipe and go... I agree with the comments for PVA adhesives and oily exotics... I use exotics on most projects – mostly for accents, pulls, etc. I’ve had adhesive failure with exotics and PVAs. I’ve had much better results with resin adhesives, epoxy, poly, etc... If you want to use epoxy, I would use West 105/206 adhesive. I have no experience with system 3 so can’t comment... 1 Quote Link to comment Share on other sites More sharing options...
davewyo Posted July 15, 2015 Author Report Share Posted July 15, 2015 Thanks Trip. I really appreciate your expertise. 105/206 it is! It's pricey...but I have a few boxes I can use it on. Quote Link to comment Share on other sites More sharing options...
Trip Posted July 15, 2015 Report Share Posted July 15, 2015 Yea, it's pricey --- unfortunately one of the few truths that runs-through the marine environment... Everything costs about double what you would expect... But you tend to get quality – I’m not sure I’ve bought a single ‘dud’ from a marine supplier... You can get the 'A'-group (pint) sizes: http://www.jamestowndistributors.com/userportal/show_product.do?pid=2031&familyName=WEST+System+206+Slow+Hardeners But you need a pump set, so that's a few bucks... I suspect you can take home a starter set for about $50... One good thing... It's got an infinite shelf life...

Brendon_t Posted July 15, 2015 Report Share Posted July 15, 2015 Aahh, I didn't get the reference. I use one for building the carbon fiber arrows for my hunting bow and tournament bow. All 12 of each set of arrows are within 4 grain variation. Very handy. Quote Link to comment Share on other sites More sharing options...
Trip Posted July 15, 2015 Report Share Posted July 15, 2015 yea bob -- spot-on, I used to for 105/206, but then got myself the 306... I use a digital kitchen scale in the shop about once every few weeks for the small stuff and mail scale about once a month for the large... scales... live and learn guys...
