Hexcel resin, not sure if that's still current. You have to use a gun to disperse it since its premixed. It has a quicker cycle time & cures at a much lower temp. Issue is that its still not as good as epoxy with adhesion, compression, flexural strengths.

It's different from the glissade topsheets. It's a rental topsheet & i don't know who the supplier is, it's not from isosport or cps. We tried some topsheets with the rubber effect, it's not a damp as the glissade stuff. Problem we ran into was two fold, one it's hard to process, you couldn't ma...

Ben, I hear you on the too much epoxy. Doesn't matter how much pressure, you can't squeeze it out. The first factory I worked at making wake/kite/skateboards in the mid 90's. We had one guy who did all the lay-ups, once he got fired or quit, my boss started doing the lay-ups & we shaved a pound ...

Sorry, just to be clear by concave you mean edge high, so if you lay the board down the center area does not touch while the edges do. On the rocker boards I have done I put a strip of carbon horizontally under the core to get a convex base in that area. So I assume the topsheet is doing the same th...

Wow, not the sharpest marble am I? Yeah that's guy, I just spaced the link. Not sure if this guy also does classes on building wooden skis. One thing is you can go to the library...found cool articles on building wooden skis. Funny, all my research use to be thru the library, not sure if they still ...

LTB a snowboard/ski company/factory out of Czech does a wood base. As you can imagine, it's for powder & doesn't hold up too well on hard snow. You could use durasurf topsheet material, it's .6mm then combine it with a veneer. There was a guy in wisconsin that made old school wood skis with edge...

Cassette are extremely helpful when glueing your edges. Just glueing edges on using only clamps isn't going to be the most accurate. If you guys use crown bases, these bases are really sensitive & warp like a mofo as it has been noted. So basically you could be glueing your edges on to a warped ...

gotcha. i was referring to if you have maple only on one side & the core is cut down the middle then the middle will eventually curve since the properties of the maple & aspen or poplar(whatever you use) are different. This is only regarding the core before lay-up

Are you applying the maple sidewalls during the lay-up or when you are making your core? If you are making a split board (2 skis) & have the maple sidewall already attached to the core you'll get a twisted core. If you're just making a board & cutting it in half after pressing then it's not ...

Biggest thing for boards is the inserts, there are iso standards you have to follow like insert depth, number of screw rotations, pull strength. You have to have a warning information posted or noted for the customer...well you don't have to, but you really need to. Insurance sucks! Well, paying for...

Sisco factory basically buys most every factory that closes down. They have the Karhu factory, the old Zoopla factory etc, they have their own base extruder but don't know how to use it, they make their own edges but they blow donkey, they can't make a board that you can mount your bindings to since...

Going off a catalog does give you the basic specs, however a lot of times the specs are fudged a bit, rounded up or down as well. I know I change the specs from actual CAD specs. Plus, it's pretty hard to figure out the sidecut radius since they are usually made up of multiple radii. Tracing an exis...
