On one pair I added an extra layer of triaxial glass under foot. On several others I added nothing. These all had one layer of 20oz. triaxial glass and one layer of 4.5oz unidirectional carbon fiber above and below their bamboo cores. Be sure to use the proper size drill bit for your binding screws....

how much does that decking material run for ? I bought nominal 1x4 planks for $2.30 per linear foot. Twelve feet is plenty to make sidewall blocks for 4 skis. These measure 3/4 x 3 1/2 inches. I ripped them into strips 5/8 inch wide with a strip left over to make into stirring sticks. Use a ripping...

My skis have vertically laminated bamboo cores with UHMW sidewalls. I'm in the process of building a couple more skis, this time using Macaranduba (Brazilian redwood) decking boards for the sidewalls. This rainforest hardwood is about as tough as UHMW but it cuts, sands, and bonds like wood because ...

I simply use a solid-core door as a work surface, 36 x 80 inch size. This is clamped to the top beam on my ski press frame. I designed the frame so this work surface is the same height as my table saw, so it also functions as a large out-feed table when ripping boards to make templates, press forms,...

Macaranduba
I proposed using teak wood for sidewalls but have since reconsidered. My preferred core material is vertically laminated bamboo (flooring boards) and I've build several pairs having UHMW sidewalls. That material is very difficult to bond with and although its tough, it tends to delaminate from the b...

I prefer angled sidewalls too. I grind the sides of the ski down square to the the steel edges with a flap-wheel sander. This grinding process results in a ski with vertical sidewalls all around, ready for the router process used to carve a bevel on the top edges as shown: http://www.fototime.com/%7...

Re: formica topsheet
I pondered this idea a while ago and concluded that Formica or any other such laminate material is too brittle. It would look good coming out of the mold but probably get all busted to heck the first day on the mountain.ralston wrote:has anybody run formica as a topsheet?

... Shif, I would be very interested to see a wider angle of your sidewall beveling jig. I haven't seen anyone use that method before. Thanks again! The chamfer bit shown has a 22.5 degree angle. I wanted to use 30 or maybe 45 degrees but that would require wider UHMW plastic sidewall blocks which ...

Double sided masking tape, three small pieces 2 inches long each. This technique minimizes base indentations: I first apply three 2 inch long pieces of double sided masking tape to the bottom of the base material. Then lay down a layer of blue 3M painters tape from a 6 inch wide roll. Then I cut the...

I cut off the excess flash using my Bosch jigsaw with combo blades. Cutting from the bottom as to see the metal edges, I try to stay within a few millimeters of the ski edges. I can cut out an entire pair of skis with one blade if I'm careful and don't go too fast. The Bosch saw has an orbit mode wh...

McMaster has 1/2" x 12 x 36 sheets, perhaps two layers of this stuff will do.

It should hold together when split lengthwise into six inch strips because it has the hot melt binder in the fill direction. I use similar uni-carbon in my ski lay up, two layers of 4.5 oz, one above and one below the core (vertically laminated bamboo). I also use 20 oz biaxial glass (+/- 22 degrees...
