Re: New snowboard construction, some help?

Make sure you also check out http://www.happymonkeysnowboards.com/Mo ... /Main_Page

Loads of info on there too in a more manageable form than the forum. But as mammuth already said, search the forum for any questions you may have as they have probably been answered before.

Re: Sidewall Help

Sounds like it should work, but it also sounds like just routing a rabbet would be less work. ;)

Re: Polyester fleece or fleecing a carbon fiber ski

Yes, the point is to keep a certain amount of resin between two layers of different materials where one material might absorb too much resin from the bond line between the two layers.

Re: Polyester fleece or fleecing a carbon fiber ski

There is indeed some sort of fleece fabric that can be used to improve bonding (we were donated some remnants of this stuff), however I don't have any Information on the manufacturer or the type of material. It is a very thin white non-woven mat, so I guess it could be both fiberglass (most likely c...

Re: Neb Powshape

For bending edges I prefer to use the modified tile nippers. You can buy them here (or just make your own with tile nippers from the hardware store): https://www.skibaumarkt.de/produkt/kantenbiegezange/

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: 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.
