how does Blizzard do it?

The IQ slider system is the best binding system I have seen (love it). You can mount any binding to the ski with one bolt. You only need one insert in the ski and no stringers or mat glass for retaining screws. You mount the binding to a thin binding plate that gets slid into a groove in the ski and then bolted with the single bolt. You have have as many of the plates as you want for a variety of bindings. I really want to use this system but am puzzled by how the press the ski. The topsheet forms around the overhangs of the track. Any ideas of how they do it or how we could fake it?

i saw something at 1:17 in the second video that made me thinking about it: "SANDWICH COMPUND SIDEWALL TITANIUM".

i think they re shaping the titanal cap 3D to form the "IQ track", and wrap it with fibres/prepregs etc to increase stability.
this forms the topsheet of the ski being pressed on top. the top mould, of course need cut-outs in those 3D areas

so how does the topsheet cap the titanal?

Seems like that would collect an awful lot of snow.

Neat rail system. Similar to the one I use by Head and Tyrolia, but the rail is built into the ski (in the first video) where as the Head and Tyrolia rail is mounted to the ski. You'd have to have some pretty tight controls to incorporate a rail into diy ski.

if you download the pdf-catalog from their homepage, you seen some cut-views of the construction

its quite simular to sir.orange's description

tyrolia also sells rails seperate from bindings too

so how does the topsheet cap the titanal?

you may not expect a topsheet like we use it (0,4-0,8mm nylon, pbt, whatwever) there are some methods that could be used instead: thin adhesive foil, coated, powder coating etc
