Chopped up some OLD skis to see the construction
Alotta different woods and metal and plastic.
The one on the bottom is a double stack core and composite in the middle, crazy.
The one above that is like ply wood or particle board and very light, Atomic. Full plastic cap.
Tough to see with my awesome cell pic but some have metal top and bottom.
Remember how stiff those old skis were. I guess because they couldn't get torsional rigidity any other way?
FLASH BACK!

Montucky, can you get a better picture?
or try it again with the skis held a little farther away(notice the stuff in the background is fairly clear).
I'd like to get a better look at that.
Also can you tell us what skis those are?
thanks

You don't even have a legit signature, nothing to reveal who you are and what you do...
Best of luck to you. (uneva)

I always thought these people could potentially provide metals for us on this side of the pond, even perhaps coat it for bonding but I have no idea.

chopped up
I am with EricW on getting a feel for your materials. You will soon find out that even the smallest change in core dimensions can have a huge effect. I am now putting aluminium in a lot of my skis. This is just a simple softish temper straight from the mill .032 thick. Not all of the big guys use titanal, and I have had no issues with bonding, although scrubbing with a beartex pad just during layup is not the most pleasant job. I do not carry the metal edge to edge or tip to tail, but set inabout 8mm from the edges and rounded off at tip and tail spacer lines. Metal .goes right over core.With .032 cores have been reduced buy atleast 2mm in the beefy part of the core. Good Luck, Mark (FOG)
I thought we were getting away from the metals? (except the edges... )

cutup skis
No chemical etching. Abrading with 40 or 60 grit, or sometimes course wire wheels. Then immmdiatly scrub in epoxy with scotchbrite pad. I went to metal in order to get more torsional stiffness and more importantly to dampen the ski. Later, Mark FOGWR WR=who rips
