For Bamboo back bows, Unibond 800 use to be the go to glue, What is the replacement for it. I have used EA-40 but was looking for something else?
-
Mark, is Unibond not available anymore?

Titebond 3 is a good, cheaper alternative, as a boo /belly wood adhesive.
That being said, I use a strong bowmakers epoxy for gluing on riser sections, as I have had some lifts at the dips with TB3, when the belly lam wasn't very thick.
A glue like unibond/urea formaldehyde is an ideal glue for all facets of wooden bowmaking. Its strong, rigid, and can take heat for bending corrections.

Smooth on epoxy or hide glue

I was thinking it was discontinued, but Facebook is saying it's still available and I found it on some websites.
What have you been using Pat ?

Yes I have used EA-40 several times on bamboo bows and a lot on glass bows.
Seems like the last few times I got it was out of date (old)
After you open it the shelf life get short.

My go to is ea 40 for boo backings. I follow the 2 parts a to 1 part b ratio. I’ve had good results for bamboo backs.

Mark, my last glue up I used Unibond that Roy (Roy of PA)sent me. Unibond is the replacement for Urac 185 that was discontinued years ago.
-
I have done about 50 BBOs starting with Urac 185 and transitioned to Unibond when they quit making Urac i85, I have never had a failure.
