This delam repair didn’t quite go as I wanted but that’s why I tried it on an old beater pair of skis. So my theory was that epoxy always seems to be a temporary fix and never really holds ski sidewalls together. So I thought about how I could screw or bolt the skis together… so this is what I came up with.




First I drilled a hole through the ski at the worst part of the delam


Then I screwed in a #4-40 machine screw in the hole with a matching bolt on the top sheet. As you can see I mangled the fuck out of the screw head. Definitely need higher quality screws next time and to be more careful.





Once I got the nut tightened down, I grinded down the screw head to be a little bellow flush with the base.

I then clamped the rest of the delamed part of the ski together and let the epoxy cure.

I first tried a p-Tex candle over the grinded down screw head but obviously that ripped right off. So I then epoxyed over the screw head and that seems to hold onto the base.

I then went out and hit some urban and smashed my skis on concrete and rocks and the sidewall held great

What do you guys think, was I high as hell when I thought of this (I was) or could this be a legit delam repair method if improved upon?

First of all, I love the thought process here haha. This is some hood shit and I'm about it. That being said, what would make this more legit is to ptex over the screw head so you don't have to worry about it catching on anything. Especially since it's sunk into the base.

Also a note on epoxy being temporary... Epoxy is incredibly strong and is obviously what they use in the first place to make the ski. The problem isn't Epoxy being temporary, the problem is once the materials that make the ski up have failed, there's no real way around that. It's just time for new skis if you want it to perform how it should.

Do you have any insight on how I could get p-tex to stick to the screw head better or at all? I tried metal grip wire on a soldering iron and it didn’t stick for shit, same with a p-Tex candle.

I agree about epoxy, shit is so strong and durable. Should have said delam repairs are temporary not “epoxy is temporary”

This is pure speculation, but what about a thin layer of wood filler or super glue or epoxy? Just something sandable and thin that would act as a go-between?

You could try to use metal grip as an adhesive layer between the screw and ptex. When a core shot exposing the inner edge popped into the shop I worked at we fill metal grip along the edge and ptex the space next to it to fill the shot. I would try that.

That's tight.

I would just changed your order a little bit:

Drill your hole, epoxy and clamp, then screw your shit down while it's clamped.

That usually helps me get tighter fits

That’s the order I did it, except I just added one clamp while I was drilling the hole at the beginning just so the ski wouldn’t separate more

JB Weld will hold. You should give that a shot.
