One of my Big Troubles delaminated at the tip after my first day hitting big jumps on them and Dynastar wouldn't warranty them. I fixed them up pretty nicely, but I work at a shop and had help from some guys who really know what they're doing - I wouldn't recommend trying it yourself, especially if there is nothing wrong with them in the first place - the ski will only be weaker like someone said before.
I spread the delam and put a load of epoxy inside first, then heated it to get it all worked in. To clamp the ski tip we cut an old snowboard in half then used that to sandwich the tip and threw about 9 G-clamps on there and left it for two days. It all set pretty solid and one of the guys told me it would probably be fine without rivets, but I wanted to make sure - Dynastar recommended to do it anyway. I used T-bolts to hold it together - a lot stronger than rivets, which aren't really that strong. I filed down the bolt half first - the length to slightly lower than the thickness of the ski and bevelled the edges so they wouldn't drag, then filed down the bolt to that it wouldn't stick out the bottom with the washers in place and the bolt tightened. Then I drilled holes slightly larger than the bolt barrel and bevelled them with a dremmel bit to keep everything smooth. I put a thin layer of epoxy round the hole to seal the exposed core then tightened up the bolts tight and evenly with
Loctite, with a wide washer against the topsheet for protection and a raised one to fit the bolt head, and left them for another day to set. Check out the end result below - it turned out pretty sweet. I threw two in each tail too, more for looks than anything else, I admit. Someone else at the shop said I could have thrown a layer of rubber in the tip for damening like a lot of park skis have now, but only one had delammed and I didn't want anything different between the two, and I wasn't sure about the whole idea. I've got park skis now anyway, so the Big Trouble is my powder ski now and I'll only do small kickers on it and minimal rails.
Once again, I had access to all the right equipment and help from some really experienced guys - I wouldn't recommend trying this unless you're confident you're not going to screw up your ski. A shop might be able to do this for you but they'd probably charge a lot because of the time it takes - if the guys in my shop were in a good mood they
might do it, but charge about $100 Canadian for it.
