Best way to fix ski delam for extended use

[NW_SKIER]

The extreme amount of epoxy you needed would change the flex and cause a radical difference in feel between the two skis.

Sounds like HE wouldn't notice.

[DaffyJeffy]

That's a good point. I think a thin glue joint would have been less likely to mess up ski flex. But I guess I'll have to wait to try that next time.

I know ski core blanks are glued together, I get that. You were trying to repair a fractured core and some de-lamination. You would never get the core back together perfectly for bonding with wood glue and you would need too much epoxy for the parts that were delaminated. It's not like you could match up the core perfectly and glue it back together and then come back and address the other delaminated parts with epoxy. Those skis are trash. I'm not part of the cool kids club, I'm just giving my opinion.

I can't make any sense of what you are trying to say here and you are assuming a lot about this ski.

I was just curious to see if I could glue this ski back together. I'm just curious in general and I don't know what else to say about that. I did learn a few things and shared them here - hopefully to someone's benefit. If you would throw them in the trash, that's cool too. I'm not going to make a moral judgement about that.

But the last time someone made fun of my socio-economic status I was in 8th grade. I'm poor, and I'm perfectly happy and comfortable with that too.

Here's a pick of the handrail pulled out. Wood glue is strong as hell and can take A LOT of bending and twisting forces. Just sayin'...

daffy - I disagree with those saying it wasn't worth trying. At worst it's a fun experiment.

Having said that, you're not making a handrail or gluing blanks together in preparation for pressing. You're trying to bond broken wood to fiberglass. Not only that but you're trying to allow flex, and a fair bit of it at that.

Why do you think slow set marine epoxy is a bad choice? The long set allows a very flexible and non brittle result. It's also very waterproof. I suggest not using heat as it speeds up the curing resulting in a more brittle result, room temperature will do fine. The epoxy generates a fair bit of heat as it cures. Having said that a touch of heat during application might help with distribution, but this should be fine if it's well mixed.

You're talking about epoxy being a poor substitute for quality wood working but you're also talking about dealing with a blitzed core so there's no quality woodwork to be found here.

As for distributing pressure, put a piece of 1/8 inch plate steel between clamps and ski and tighten with a snipe.

Wood glue is only useful in skis to hold your core blank together while you profile it and lay it up (with epoxy).

lots of assholes here

and everbodies got one eh?

Something that I mentioned but perhaps didn't stress enough is that this ski, technically speaking, was not a "delam". The wood core literally ripped in half. So I would in fact have been gluing wood to wood. but I completely agree if it were wood to fiberglass or any other material, epoxy is the only choice.

And I didn't mean to imply that slow set marine epoxy would be a bad choice. I appreciate that suggestion and may need to use it in a different situation.

I think the large amount of surface area here was the largest obstacle. If I was convinced I'd get good squeeze-out with some formulation of epoxy, that would be the way I'd go for sure! Using compressed air to spread the epoxy did work quite nicely - I'd do that again (it was quick too).

Make sense?

So you mention that little piece info now and you wanted to fix it with titebond ... are you FUCKING kidding me?

not only did you waste 10$ worth of epoxy but I wasted time reading your post that i will never get back again

I don't know what to tell ya dude...read more carefully perhaps? I explain this very clearly in my second post. My exact words were "Like I said, being that it was the wood core that literally ripped apart, I should have used Titebond 3". I don't know how I could have been more explicit? I could have put that in all caps I suppose?

I never asked any questions, I just posted this to be instructive in a don't-do-what-I-did way. Clearly a ski that has come apart like a sandwich - either through glue failure or wood fiber failure gets glued and clamped in one way or another. Since I chose to use epoxy, it is entirely relevant to this thread. The fact that wood glue could have been used (in my personal opinion) is not relevant to this thread. I only mentioned it in passing. Commenters have kept this conversation going and I'm happy to participate but as I also said, I apologise for this becoming a thread about wood glue vs epoxy. That was not my intention. The only thing that kept this going for several pages was people asking me questions and speculating...which is fine, I'm happy to participate.

you didnt say broken in half which not the same as delamed but in any case I just can't believe someone would try to glue a ski that has broken in half back together with any type of glue and it sez more about your sanity than your abilities as a carpenter

[skifishbum]

yo jazzy jong you should pm marshallolsen and ask him to come back and teach you not to suck

[I've seen black diamonds!]

You should just a make a whole ski out of glue.

You're quite good at putting words in my mouth. The ski was not broken in half.

Here is some woodworking 101 because you clearly don't understand how wood works: Wood fibers, on a cellular level, are like long bunches of straws. A ski core essentially has these straws running the length of the ski. These fibers pulled apart ripping the core open like a sandwich. These fibers are not what gives wood (or skis) their strength. A glued joint here would be infinitely stronger than the wood grain itself. The wood grain in this ski was not broken across the grain it was severed WITH the grain, which is why it was such a clean, non-fibrous split (have you ever split wood a day in you life?). This is a prime candidate for what wood glue does best - gluing the long grain.

I'd try this again in a heartbeat with titebond 3.

I know you kids love a good "internet pile-on" so have at it. Whatever gets ya off.

[NW_SKIER]

Whatever gets ya off.

Does this mean you're going to post some titty pics finally?

k2 basically do this. they use a wood slurry.

Yeah it looks like you keep changing your story, I know all that stuff and I have pressed the button on a wood splitter many times in any case this is all highschool woodshop stuff not rocket science, I also know the better part of being a Carp or handyman is knowing what job NOT to take on

Carps?
did i ever mention i knows carps?

[XXX-er]

well sure a guy named "skifishbum" would have lots of fish porn but I think the rest of the kids want titties eh?

Don't be so sensitive Daffy, it's like throwing chum in the water when there's sharks around.

The "sharks" are usually living in their mother's basement in New Jersey pretending that they're a real skier whilst making a part-time career out of commenting on the TGR forum. LOL, I couldn't care less. Have at it if that's your thing.

I've met a fair number of the people posting in this thread and most of the others are known to the people I've met. I can assure you they're not posting from their mother's basement(well maybe) and they're real skiers.

Bump for some G-flex repair in the works.
