The finish looks really great Gav - what's your recipe on veneer? I use a 3 coat wet epoxy on wet epoxy. I then polish it using various grades of wet and dry. I get an absolute mirror finish. I tend to make skis, and the problem I have is that they chip very badly - any views?

Yeah veneer durability isn't as good as the plastic type topsheets.
I have found a couple of ways to improve it a bit.

I mix up about 50 grams of resin and then thin it right down with about 10% ( so 5 grams) of acetone and then brush it into the veneer. Work it in so it soaks right through it. Can add more acetone if you need it to soak through more.
I then put it in my press and press it flat with light pressure and normal epoxy cure heat. When you pull it from the press leave it in the cassette to cool, otherwise it will curl right up out of shape. You can let it cool in the press if you want.
You will end up with a much tougher veneer that is nice and flat and really easy to work with.

If you are finding the epoxy topcoat is chipping you are using an epoxy that is too hard or the coat is too thick maybe.
What resin do you use? It's not West System is it? Boat resin is usually really hard.

Oh and i grind the sidewall with two angles.
The first angle is the normal angle then i add a nice sized 45 degree all around. The flatter angle around the top seems to protect the edge of the veneer a lot more.

The topcoat on that latest board is a polyurethane clear coat. I've used epoxy and polyurethane. I prefer the polyurethane.

hey Gav, the red board looks great!

Regarding approach skis, We rode every approach ski - snowshoe variation we could think of for the decade before splits came out here in Utah in the mid 90s. If you are climbing and breaking trail in good snow they really make little sense. It is just too redundant to have wide approach skis on your feet with a board on the back. Especially since you can make your own sub 6 pound splitboards. I'm not trying to rain on your parade, but I think that you might quickly put a pair of well-engineered approach skis in a dusty corner after comparing a day with them versus a day on a really light split.

Maybe the cloth hinge could be a part of a superlight 3 or four piece split like Phenix makes.


The exception might be if you have superlight, narrow approach skis and are climbing in firm to shallow snow like the guys in Italy do, they are probably pretty good. But if they are superlight Balsa-Paulownia-carbon deals, will the swing weight be so bad to require folding? Also you really don't need length in those kids of conditions.

There are a few touring routes here in Utah with a longer low angle approach that puts you right at the foot of a steep wall where you could argue it is more efficient to get there on superlight skinny xc skis, then leave those at the base and put in a vert track if you repeat the climb three times or more on the vert track. Back when we had altimeter watches we probably had our fastest ascent rates over the whole day from re-using a vert staircase several times. That may have changed since splitboards got into the five pound range, we don't know.

But generally we go from place to place and break more trails that aren't all super steep all the way and want the freedom to not go back to the same spot where skis may have been left on the way out. The guy behind Mountain approach had a prototype out there with fabric hinges, but my guess is the market doesn't want it because it's just more weight and expense.


Hey Dave I tried to message you but it won't go through. Is your inbox full?
