RE: Is epoxy a must?
Cheers John. I will gove that a go next time!!
For the record, I ended up using wood glue. Doing a rather exagerated pull test, the only movement weas the back of the fus merrily bending under strain. I think it is safe to say the wood glue is strong enough!!
one thing I did notice though, wood glue has very little grab so lots more pins and tape were required than if using epoxy. Not a problem....if you know about it first, more hassl;e if you dont have any pins at all and the tape is in the loft!!!
