We succesully profiled a test core today (a plank of pine) with our planer profiler, here are the pictures:

Me holding the profiled plank, it is alot shorter than our cores will be but this just gave us an idea on how well the system works, tommorrow we are going to shop for planks and hopefully laminate some cores!!
 
no worky for me........ but the grip tape thing worked like a wonder if anyone wanted to know.
 
well... the test run was just a pine plank we found. our cores will probably be some sort of a combo that could include birch, maple, oak, poplar, etc...

we are going to the lumberyard tommorrow to get prices for some high grade lumber and i just ordered the rest of our materials off of skibuilders a couple hours ago
 
i'm still a little confused on how the whole planer profiler actually works. in all the pictures i've seen of a core being profiled this way, there appears to be a nice transition from the thin tips/tails to the thicker core. however, with the planer on a straight horizontal axis, and the profiler on a slight "z" (diagnol) axis, it would seem to me like the profile of the core would result in the shape of a trapezoid. can someone clear this up for me? i've spent days milling it over in my mind, and the only solution i can come up with is either

1. you sand the corners of the "trapezoid" it creates

2. the pressure of the blade lessens on the core lessens as the profiler allows the core to become thicker as it's being pushed through, which would mean as it goes though, there would be an equal amount of pressure being relieved all the way through which would allow the core to relax as it's being planed.

get me?

thanks!
 
Remember that lots of cores are trapezoidal in shape. Many have a flat section located where the bindings are to be mounted.

Some are continuously changing, but some go up, get flat for 20-40cm, and then go back down.
 
here is a pic from the ski builder's web site

I am pretty sure that 99% of skis have a flat binding area. I know that all of my park skis do and from what I can tell my mom's carver skis have it to
 
so how do you get the tip/tail sections flat when you use a planer profiler? i understand how the binding area flattens using it, but the tip/tail, those few cm's where it's uniform thickness?
 
i haven't figured this out yet. it would be possible to make a dual horizontol/vertically laminated ski though. plane one core with the tips going down to litteraly nothing and plane a flat core down to say 3 mm then vertically laminate them....
 
Just depends on the flex you want.

The ski will have a rounder flex if you have no plateau in the center. I will likely try both and see if I prefer one.

I think either way you are ok though. Just don't make the curve in the center of the ski drastic or you will have issues with the bindings.
