Camber question

OK, So I'd like to build a press form (ie. the bottom) that I can use formultiple ski desins ranging fromrockers to normal. So I figured that I'd make it out of MDF, with members for the main camber (even the rockers will have some underfoot) and the tips, with the tips being interchangeable for the...

Mold dimensions

I'm in the process of building a new mold, and would like to vary the sidecut, width underfoot, etc.. of the ski. Furthermore, I'm trying to build it as a "vacuum box" that will allow it to be inserted into a pneumatic press (eventually) and have the mold be exchangeable within the box. I'...

I used a few stringers of hickory in an aspen core ski (simmetrical in the center with 1@ 2 laminates removed from the center. I thought it would add a more "low frequency" spring.
All I know is that it looked cool, as for effect ???!!!

I remember figuring ~ $80 for materials / ski. Of course the initial investment is higher since you'll want to buy materials for multiple skis (it sucks to run out halfway through the build, trust me) and the equipment needed to press / profile / glue up. Vac presses are cheapest, check ebay for &qu...

Yeah man!!! Glen rocks.
He got locked onto a sailboat with me for ~4hours about 14 years ago. In TEXAS!
He's got a great attitude, one that all skiers should strive for... just having fun on snow!

While I've only built one pair, I did use them to fore-run an extreeme comp course. Whistler sounds Awesome, especially in February!!! Let's see if schedules line up!

I've made an epoxy " cap" ski, and although it wasn't easy it wasn't super difficult. I ended up having to press it twice, as the first time the bag didn't wrap around the ski as I would have liked, leaving some rough, uninfiltrated fiberglass sheet. After the second press, I noticed that ...

diminishing gains.

I built my skis using a vacuum pump, and am currently trying to build a combo Vac / pneumo press. I got my pump from ebay quite cheaply, it's a "roughing" pump used for backing high vac systems, or clearing out atmosphere's in chemical environments in order to backfill with inert gasses, b...

Yeah, this would be for the core. Basically a way of making a half dozen basic shapes and then varying the flex properties with a second top layer.

horizontal laminate for flex control

I've been thinking about a combo vertical / 2 layer horizontal laminate idea where the bottom layer would be a standard easily built, lighlty tapered layer with the top layer being a more structured piece shaped for stiffnes both torsional and flexural. I'm a bit worried about the horizontal layers ...

Stress calculations for I-beams

Hi, After a pretty successful vacuum pressing experience I have been wanting to build a pneumatic press. I've been able to score a bunch of 10x5 .25" I-beam, and have wanted to first calculate what sort of stress they will endure and how reinforced they should be. As I'm being lazy, I was hopin...

stiffening strategies

My first pair of skis carved really nicely, even though my first examination of the flex pattern showed that they turned out to be really soft. While I was actually enjoying the soft tails since they avoided me having to be in the back seat (these are alpine skis, when I get confident in the durabil...
