Topic tags/keywords: bubinga question

I have a project, which is using laminated bubinga.
I am thinking of using epoxy instead of DAP weldwood because of the oily wood.

I like the epoxy idea because of the wood and because of the long open time.
I am planning West Systems 105 +206 hardener.

However I have heard that epoxy “Likes” a fatter glue line and it is easy to get into problems with delamination because of overclamping and glue starvation. Wheras with PVA glue it really is nearly impossible to overclamp, that before you would get starvation, you are physically crushing the wood fibers.

I’m trying to sort out the “Real” from the “My friends, cousins neighbors grandpa said…..”

Is Epoxy a bad choice for laminating 1/8-3/16 strips to make a rocker? Or is there something better. I also want little to no springback.

Thanks

I’ve been using the west system for at least 30 years and never ever had a glue failure. And never had a problem with over clamping. I use it for style and rail joints because it is so thin I hold it back from the corners and only have to sand the flat sides. I have used other epoxy’s that are thick like malaises but West is not like that. I might add that I worked in the custom boats when I was younger and everything was epoxied and everything was Teak a very oily wood. These were ocean going yachts were peoples lives depended on it.

Thanks for all the help. Seems that regardless of glue the acetone wipe is important.

I was surprised to hear from David about the joint failures…since Epoxy is typically touted as the solution for oily woods rather than being imcompatible, and that it is the water base PVA that don’t adhere. Learn new stuff every day!
