DOMINO as a FASTENER?

[roblg3]

A man asked me to repair his horribly done IPE landings.  I'm wondering if anyone has tried or thought this is a good/bad idea?  I was thinking of through dominos as the fasteners?  titebond 3 and maybe a through screw in the domino in the joist?  Does this description make sense?  and is this a terrible idea?

Use the sipo dominos. I think I know what you

mean but I'd be leary of moisture.

Good luck now.

for clarification, INSTEAD of screwing the deck boards down, i had an idea of using the dominos as the screws. ????
i think this is probably NOT a good idea, unless someone can say they've done something like it?

Yes I have.

The seat is held on the stool with 3.5" long white oak dominos.

The window corner is locked together with crossed dominos.

Make your own tenons out of Ipe.

Wow Tom, beautiful bench!  i was thinking the sipo tenons.  this deck will get a coat of ipe oil when completed.  I really don't want to look stupid. it just seems like a cool idea?  just dominos and waterproof glue right?

Tom, yes the bench is beautiful.  But this situation is different.  First, two cross grain glue joints at every joist.  Also throw in the glueing to pressure treated.

Use West Systems Six10 epoxy. Make sure you wipe the mortice with acetone.

I would use the XL and plunge through the plank into the joist, clean well, inject epoxy, drive in tenon.

It seems like i'd also be removing alot of material from the framing. and in the top 1/3 of the structural strength area too.  i'd basically be notching the crap out of it.  thanks for helping my thing this through guys but this sounds like a definite no no.

Having just built 8 large benches out of Ipe, I'd agree with the " don't do it" suggestion. I found Titebond III dries extremely slowly  in Ipe and I relied on it only for gluing large areas (2 1x6 boards flat side to flat side) and I reinforced those joins with stainless screws.

The boards for the tops were joined with 8mm Sipo tenons glued with epoxy and pinned with 1/2" screws at each end. I let the epoxy dry for 12 hours before unclamping.

I just don't think Ipe would bond strongly enough to a cross grain tenon to resist the stress of repeated foot steps.

I'd fasten the Ipe boards with stainless steel screws. You know Ipe splits like crazy so pre-drilling and countersinking is mandatory.

You could sink a few dominos in strategic places to help line things up, then fasten with screws instead of using glue...

I spoke to West's technical help there a while back for an outdoor Ipe situation I'll be working on and the product they recommended for outdoor use was the G-Flex due to it's ability to withstand/accomodate stress/stretching which can be catastrophic in outdoor applications.  Has almost all the strength of their regular epoxy, but has the ability to stretch a lot more.

I used the West Systems GFlex for a few applications, I like it.
