Repairing or Replacing Die Cut Base?

Hey everyone, I did a quick search but was unable to find any relevant threads about repairing die cuts. My friend Jordon got a messed up prototype split board for free, and he wants me to help him replace some of the die cuts in the base. http://i571.photobucket.com/albums/ss151/nickmarshall542/rom...

Thanks for all the suggestions. A straight joint is definitely the worst for a failure, a crack wants to propegate in a straight line, and this just helps that. But, it's also the quickest method, and that's why I do it on my skis, its a trade off. Yeah, same here. I have never had a problem with it...

The nose became unhooked from his snowboard rack on his sno...

I have had cores tear out this way when using a smaller radius router bit. I started using one that is over 1 inch in diameter and haven't seen the problem anymore. You dont have to cut as accurately with the bandsaw also.

I really like the idea of pre-heating composites and resin, thanks Richuk. I have warmed resin in front of a heat lamp before, but never the composites.

There was no peel layer on top of the carbon fiber. Just a smooth, clean, waxed cassette.

Yeah I have noticed that too, I was guessing that I am not getting the fiberglass fully wet out in those areas? I have used qcm's emv-0043 resin and eca-032 for almost all of my skis. In my opinion, its has a pretty high viscosity and it takes a litttle bit of work to get it into the glass. Sometime...

Could be a few things, like Vinman is saying ... just wondering how much pressure are you using? Looks like telegraphing through the base, which is a surprising - too much pressure and heat? As you are making skis for friends, it's probably worth asking what you have done to resolve the dry fibre i...

My first though is are you routing out your sidewalls to accommodate the thickness I the edge teeth? I use a .9-1.1 mm rabbet. Second thought is do you apply pressure before turning your heat on? I pressurize for 10 Min prior to heating to allow the epoxy to squeeze out and just sort of flow though...

How flat do your guys' bases come out? Is there something that I should do differently or should the guys at the local ski shop spend more time grinding them down? http://i571.photobucket.com/albums/ss151/nickmarshall542/Ski%20Building/PB070102-2.jpg That was after they tuned them up.

The core profile that I use for skis is usually about 2-10-2, with the 10 mm section being about 45 cm long in the middle of the core. For splitboards, its about 2-7.5-2, with the 7.5 mm stretching for about 70 cm. They all have 20 oz glass above and below the core, and some of them have a strip of ...

Placement of the strip of wood is critical. Exactly. I sharpen the pencil that I am using for and spend lots of time clamping the wood down before sinking screws into it. the last photo kinda reminds me of ON3Ps first batch of skis. and look where they're now! way to go! :D After doing this batch o...

Wow, you've been crankin' out the skis. Did you have a separate template made for each one of those skis? Or do you have some other way of shaping the skis? You have so many shapes and sizes. I cut out all the templates by hand. I built 12 different shapes of skis this summer, with 8 new shapes to ...

Here's a few notes on how I built the skis. Most of these ideas or processes have already been posted here, I just thought I would let you guys know what worked well for me and what didn't. I profiled all of my cores on an adjustable router table. I saw one in a layup video (I think it was from king...
