Re: Round Top skis 19/20

You could use so-called hermetic wire connectors or hermetic wire feedthroughs to connect the wires and keep things airtight.

Re: FFC 2019

In the thread for the children's snowboard he said that he used the printed fabric from here: https://www.freaksoffashion.com/produkt ... 52f3c22ed6

Looks like he covered it with a transparent topsheet.

Re: Ben_Mtl 2014... skis and CNC

Looking at the pictures of your CNC again I just noticed the feet under the bed in the middle of the long axis. I guess that means that you do not have a connection between the side pieces of the gantry underneath the bed to stiffen the gantry (unlike the platform cnc). Does that cause any problems ...

Re: Methods to keep core/ base still during press.

Looks like this should work. I would superglue the base pieces to the side of the edge in addition to the tape.

Re: Snow Surf - Ptex to full wood core

I would bend the wood first and add the base in a second step with a vacuum press as this gets you uniform pressure all over the area of the board, which not easy to achieve without a pneumatic or vacuum press. You don't necessarily need a proper vacuum pump for this (although it draws a higher vacu...

Re: UD Carbon strings on a carrier foil

This stuff is often called "fused carbon". Here is an Australian shop (with reasonable worldwide shipping on smaller items) that carries a variety of tapes: https://shapers.com.au/non-woven-tapes/ ... ing&page=1

Re: How to avoid unevenness of the base between the edges

What mammuth said. Everything you're asking has been discussed on here before.

Putting the veneer underneath the glass will make it easier to place, but it will make the ski less stiff as the distance between the reinforcements is decreased.

Re: How to avoid unevenness of the base between the edges

The picture you posted is exactly what most people do. Search the forum and you will find a few solutions on how to position the core exactly in relation to the base (for skis I usually drill two holes in the core and superglue short dowels to the base that go into the holes in the core). The method...

Re: How to avoid unevenness of the base between the edges

Are you milling a notch on the core? That is exactly what most people do. If you search the forum for "rabbet" (the term for such notch), you will find some more info. Another option is to use some filler fitted between the edges that is the exact height of the edge Tangs. I think someone on here h...

Re: Bamboo/Cork Sidewalls

That is most probably not just pure cork, but a mix of rubber and cork. Capita uses this stuff in some of their park boards (Ultrafear model) as well and it holds up fine (a friend of mine rides one with countless park laps on it). We also received some samples of the rubber cork from the manufactur...
