Junction/transition core-tipspacer

Post by Hannes »

As I am planning this years projects I always come up with new questions. Playing with SnoCad made me think of the different options of designing the tipspacers.
Straight junction or with interlock, radius or no radius. So far I always worked with a radius as I learned as kid when building rc-planes to never ever have an abrupt junction of two materials in a wing spar. But I have seen quite a few pics of skis with a straight junction of core and tipspacer.
How do you guys handle it? Do you have troubles with a straight junction? Am I having to many thoughts?

I have tried pretty much each way to do it and nothing have failed yet.

I think most builders use a butt joint. I've also seen some builders integrate the core and tip spacer with a V. I use the butt joint and never had a failure. Since the butt joint is sandwiched between fiberglass and/or other laminates, it ends up very durable.

Yup, always worried about that and made the transition a V.
The problem is your core tapers so the thickness varies, this means your 2mm tip spacer is not the same thickness as your core for all of the junction.
Started going straight across butt joint a few years ago and have yet to see a problem.

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

Best of luck to you. (uneva)

So I will use butt joints this year. This will make things a bit easier.
Thanks guys!
