I read it increases compressive strength of a laminate by 13% to 18%, but much more of an increase in strength after a tested laminate has had an impact. I'm not so sure that skis and boards are experiencing impacts on top side where this increase in compressive strength would be significant. On a r...

Let us know how it worked out. It looks like it clips are not that sensitive to being perfectly lined up along the nose to tail direction. If they don't line up you can always fabricate a basic clip like I do and template the holes for where the screw posts are. I kinda think these clips and the ide...

I have done ski screws into Ipe wood plugs set in the deck with success but that is with a much thicker board than standard and vacuum pressing the deck composites. The above picture is one insert and one ski screw per side. I have often thought that a cool approach for a thinner more standard board...

I've had excellent delivery from snowboard materials for years (more than a decade probably). Just order it.

hmm, everything I've read independently and learned from family members in the aerospace field is that resins resist impact, cracking and adhere better after their specified temp cure from linking up and forming longer molecular strands.

Hey stormyclouds, Love the elm topsheet and the tints as well! Are the gray and green boards tinted resin? They look pretty awesome. I reckon your next step is to heat cure. It might actually add stiffness, but definitely will add toughness and adhesion to your laminates. Even 130 to 140F for two ho...

Have a look at 1/2" carpet tacks, super sharp, flat heads which should bond well despite a smaller head size.

Thanks for the share. I had a similar break in a full paulownia core, (snowboard). Right between two reinforced areas. Strangely I have another board with the same lay-up but with veneer, and the veneer has prevented the topside from buckling. So maybe I would not only feather out your binding area ...

Hey Gav,
I have an open drum sander like that, what grits do you start and finish with and do you mist the base each pass. Thanks,

So have you had good adhesion and no easy chipping after applying a gloss coat to the texture left behind from peel ply? I guess you are saying yes. I'll have to try this. I've always been afraid to add two part gloss coat to surface left after peel ply without sanding. I hand sand the texture with ...

I understand that they grey film is a bonding agent that helps the adhesion of epoxy to the steel. Like a primer coat. I'm not sure if this makes for a better bond than sanded or sandblasted steel, but perhaps it prevents oxidation prior to laminating the edges in a board. I have always just laminat...

right, like richie said any shim (or leveling) will also have to shim the surface where the clip from the opposing side rests. Alternatively, couldn't you mill or file down one half of each or one clip so that it compensates for the board thickness that doesn't match instead of trying to alter the b...
