split ends

Post by the.quass »

Hi everyone,
Quick question. My cores crack/split quite easily along the grain in the tip and tail. They are 2mm thick. I am guessing as long as I keep it flat when pressing the epoxy will fix this up? Incorrect? Thoughts?

Should be alright, Ive had a couple where the glue line came apart and they look and ski pretty darn good.

You don't even have a legit signature, nothing to reveal who you are and what you do...

Best of luck to you. (uneva)

yea i think everyone's had this issue at the tips when we get down to a 1.6-2mm tip. you can always just re glue it with wood glue if it scares you.

Good luck with the first build man!

Nordica - the old video of the wood shop used to show a guy stapling the stringers, but that's no longer the case.

Probably not 100% relevant to your problem, but I will put this in here anyway rather than starting a new thread.
I have been using a flush trim bit to cut the ends of my cores to length.
Always had trouble with the router exiting the cut and splitting the laminate along its glue lines. I would try to climb cut from the other side to complete it, which would mostly work. At worst it would actually chip a piece of core off when it would exit the cut and I would have to try and glue it back on.
This is wood working 101, but I like a lot of other on here I would guess, were not experienced woodworkers prior to starting ski building. The last cores I did I supported the cut with another piece of core cutoff and it stops the router breaking off the edge of the core when you exit the cut.
Support your cuts - woodworking 101 apparently

Support your cuts - woodworking 101 apparently - Right on Falls.

I use a similar method where the core is supported by the end of the table. But I use a jigsaw with a downward cutting blade and a speed square as a guide.

I use my chop saw. radial arm saw, or my table saw with sled. Which ever is not covered with ski building stuff ;-) Router or Jig saw were not two that i would have considered, very interesting techniques.

Another core related question. As I am not using sidewalls would I still need to cut my core out exactly to shape before pressing? I was thinking I would leave it slightly oversize and trim this when I cut the board out. Is this dumb? I can still rabbet (sp?) For the edge prior

Leave it over sized by a few mm or so on each side. You can still rabbet for edges, just account for the additional wood sidewall.

Thanks skidesmond. Also, i have heard people rabbet by eye so any extra gap will just fill with epoxy or does it need to be perfecto.

Using a fence or roller guide on your router makes it super easy to get a tight rabbet. I give it about 1 mm of wiggle room.

Just use a rabbet bit with a guide bearing. I use a 1/2 inch rabbet at .8mm. I know I'm mixing units...

Your rabbet width may vary depending on your sidewall thickness and how much you leave as extra that gets cut off in the flash. I leave ~3 mm in the flash.
