Snapped core

I bought a pair of atomic patent's 09/10 185, at a ski swap for $15. One of the skis is mint, but the other one has a snapped core a fifth of the way up the ski from the tail. I bought the skis for use in my backyard and the toboggan hill. Is there any way to fix this?

*Disclaimer: I have never done this nor do I know if it works. I am only assuming it might.

If you were to epoxy it and clamp it together it might stay together for a little while but i am not sure how long it would last.
 
Sorry, these methods won't work. Adding stringers to the top of the ski or reattaching the top sheet with epoxy provide the ski with material to take the compressive loads when the ski bends. However, the core will still be broken and unable to carry the shear forces that arise during bending so the ski will buckle here.
 
even if you were to almost fill the core with epoxy. i realize it wont be anything like new but still would it stay together?
 
Depends how the core snapped.Hard to say from the pics. If it's a long, layered break with lots of bits sticking out and you epoxy the hell out of it and clamp it then it may just act like a finger-jointed piece of wood (which cores often have anyway) and hold up for a while.If it's a clean break through the core and has just caused the topsheet to buckle like that then I'd say the first time you ski it it will fold up again.
 
i may not be offering a fix but i know patents are known for having weak cores so there is a decent chance someone might have an extra un broken ski they might sell you cheap if you put up an WTB in B/S/T
 
the brake is long and layered and not too deep, if you understand that. I'm going to fill the core with epoxy and clamp it like hell. Then I will put one layer of fiberglass on top, then some carbon strips, then another layer of fiberglass. Anyone have a good cold weather epoxy?
 
Hell no. Wood filler is for doing exactly what the name suggests.
You want a good epoxy resin and some smallish flat bits of wood at the very least to spread the clamping force over the whole break. Just absolutely soak it in resin, make sure it gets into the core and all. Put tinfoil over the topsheet and base so your clamps don't stick to them then clamp the heck out of it. It'll be ugly as hell but it just might work.Be careful with the resin, it's nasty stuff.Assume anything you get it on you'll never be able to get it off. And wear gloves.
 
You can sand it off if you're careful. Wear a respirator.

Also, most resins will bond weakly to plastics... go check the scrap bin at a TAP plastics for some.
 
If the break is largely confined to one layer you may have a chance of getting some use out of it. However, this would require getting epoxy into all the gaps and most adhesive epoxy would be too thick. Normally the epoxy will become less viscous if you heat it up which will help get it into the gaps. The downside is that a 10 degree increase in temp will typically halve the cure time. If you can get some laminating resin you might have a shot but I wouldn't be too hopeful
 
BUMP

I ended up putting some marine epoxy inside the ski and then some fiberglas mat on top of the ski. See crappy pics. The ski feels like it is pretty strong torsionally, and good enough for some backyard rails.

Patent's are symmetrical, so should I mount the skis backwards?
 
i'd think not. cause i figure you have more of a chance landing backseat and snapping them than you do landing to far forward.
