Homebuilt ultra light Sitka spruce wing. and let me say this stuff is the boss! Used by wooden aircraft manufacturers for decades, this epoxy has an excellent reputation. and now i know why! It may take time to get used to measuring the right amount for the task, but this material is durable and won't shrink. It grinds pretty easily. You can glue anything to anything! Stronger than the tree itself. If it's well tried and tested for use on wooden planes where your life literally depends on it, I'm sure it will work for your furniture or boat building too. highly recommended.
