Careful... a 13mm thick core underfoot will be HEAVY!! On a ski that large, 13mm is a lot of weight! My final ski is 3mm at the tip and tail and 11.5mm underfoot... It is fairly stiff for a big guy like me but I am a little worry about its weight (2.7kg per ski). I haven't try them yet, but it feel ...

Ok... they are finally done!! Right out of the mold! http://lh3.ggpht.com/_i7KmwxUlMvY/SUaIwUrTGCI/AAAAAAAAFAo/CV6ZsolgOBc/s800/ALD_0948.JPG Trimming them... http://lh6.ggpht.com/_i7KmwxUlMvY/SUaIw--4gPI/AAAAAAAAFAk/QsBi9ZTcGFc/s800/ALD_0959.JPG Finished product! http://lh6.ggpht.com/_i7KmwxUlMvY/SU...

Here we go... I have one pair in the bag, waiting for them to cure. I had a few problems during the layup (mostly with the scale working randomly... bad) but hopefully they will turn out great... here are a few pictures: Maple and poplar core (this time it is 3mm at the tip and tail, 12mm underfoot....

I am not sure why it is doing craking noise, but even skis sold at REI (Volk, K2, Salomon) do that when you flex them... I was surprised to notice that last week as I was testing the flex of some of them. My new Karhu are not doing that, and even my home made ski lacking some resin on the top layer ...

Hi, I was thinking about putting some watercolor paper in my ski under a clear base (to have some white pattern), but I am a little bit worry about the delamination. I did a quick test with 30min epoxy and watercolor paper doesn't seem to soak all the way through with epoxy... once cured, it is pret...

So I tried breaking my ski using the well known "Karhu technique"... just to see how solid it is! And made a video of it... http://www.facebook.com/home.php#/video/video.php?v=41013721602 Basically everything hold well. It amplified the PE sidewall delamination problem in the rear of the s...

So I made a pair of skis... they look good. I flexed them a bunch in the past few days and I am already seeing some delamination between my p-tex sidewall and the fiberglass! I search the forum and found different answers. Seems like flaming is hard to accomplish properly. Any tricks? Do you sand yo...

I had similar problem with 1/4in masonite... I end up using an knife to cut lines about 1/32in deep on the back of the board. Then it bends pretty easily... http://lh4.ggpht.com/_i7KmwxUlMvY/SRetq1B9IJI/AAAAAAAAD7k/_hg_6FyZYWk/s800/ALD_0634.JPG I had to glue it anyway on the mold, so I just put a lo...

So I made it! :-) The mold... Flat camber, about 12in of tip rocker... http://lh5.ggpht.com/_i7KmwxUlMvY/SReth9hSnVI/AAAAAAAAD7Q/RyurJ39r7u0/s800/ALD_0623.JPG Glue a layer of 1/4in melamine on top of it... bad idea... super hard to bend (should have used 1/8in) and the melamine "bubble up"...

The results were surprising. Most skis have a deviation of about +/-1-4mR from the right to the left side, in average the radius is pretty accurate, but it seems that all have a major problem with warping of the base material before layup. the two skis of a pair usually bends the same way. It is fu...

Hey,

My first pair of ski should be out of the mold in less than a week... Any of you have access to a belt sander to flatten the base and a stone grinder? Or know where I can get my ski tuned?

Thanks!

Alexis

They have mold that if you curve the edge on it, it springs back to the correct shape of the ski... obviously it is not the same shape as the ski (a little bit as if you want to bend a sheet of metal at 90 deg, you need to bend it to 95 deg and it then spring back to 90 deg) and the shape is not eas...

The rubber is not on the drawing... but I got a roll of it and it will be on my skis! I got all the material from skibuilders.com, the vacuum stuff from aircraftspruce.com and wood from a local retailer... I haven't started doing the sidewall bonding yet, but I am planning to do exactly as described...

Hey Fellows, So here I am, making my first pair of skis! Got all my material and now figuring out the last details... I thought about posting my CAD drawing out here, just in case I did a pretty obvious mistake! Please let me know! So it is a 150-125-130 ski... Pintail design, kind of an hybrid betw...

Hey Fellows, So I am planning to build skis... a nice fat pair like the Megawatt or the Lotus 120! But as I don't know anything about the process (vacuum bagging) and want to have a decent first pair of skis... I first made a pair of small skis! Took about an afternoon for each of them... :-) So her...
