sipo for outdoor, how really necessary is it?

[vrasilla]

I've had both domino machines for a couple months now purchasing them just a month apart and have only cracked the boxes. Before I get them out on site I wanted to get familiar and spend a weekend doing a couple things at my house particularly some new doors for my tool shed and driveway gates. I have all the standard beech tenons I'd need and was considering gluing them up with gorilla PU glue so it swells and foams and kinda encapsulates them but what are some opinions out there on the actual need to use the sipo tenon for these outdoor projects. Anybody have any beech domino outdoor work that has failed or rotted?

Thanks,

How about Beech Biscuits failing.  That's how I first ran into Beech not working for an outdoor application if water got to the joint on older biscuit joinings that I used to do. So, with Sipo available, I recommend it as extra protection for an outdoor joint that you've made, to survive long term.  [crying]

I've used regular dominos to glue teak for use as a boat stern rail seat.  Its been out in the weather for 5 years now w/ no problems, but I used West System epoxy for the glue up and made sure that the domino was completely coated.

Hi you could always make you own dominos out of whatever you are making the gates out of, you could make custom sizes to suit your project

You could get away from not having to use Sipo's it seems, but why take the chance.

Yeah, I guess it's a small price to pay for the sipos and to be sure it'll last long term. Making my own is a great idea.

Thanks
