Re: Need help with kid snowboard

I've done a couple of boards with 450gsm fibre top and bottom, 0' / 90'. 6.7mm core and they were really quite soft, even with some carbon fibre added. You could grab a bit of 5mm wood that is about 230mm wide and press it with glass and Ptex and see how flexy it is. Even a 900mm length will give yo...

Re: Need help with kid snowboard

Check out Divide Rides journal, in the last few pages he goes through the build of his kids board, has the whole layup in there I think.

Re: Need help with kid snowboard

The only problem I see with really thin cores is the very small inserts you will need and they will only have three turns on each screw.
I would think about 450gsm glass with only 45/45 degree tows.
Then a 6mm core will still be plenty flexy.

Intermediate women's powder ski

Hey there you awesome two plankers I need some wisdom. My missus has finally found the love for off piste and backcountry so I want to build her first pair of freeride type skis to encourage it even more. She is a mid level skier but better than she thinks she is, but I'm a boarder not skier so I'm ...

Re: Prototype 1

Even a 156cm custom X has about 1150mm running length so I'm not sure how your powder shaped board could have more camber than your custom X. Magnatraction works, it's not a gimmick. Your effective edge and running length is pretty short and your shape and camber profile probably don't match well en...

Re: The pouring urethane sidewall thread

Hey Fred, what's the viscosity like of this product you are using?
Results look good but that pot life is damn short, I think I would need something that pours pretty easily and levels from one end to be that quick.

Oh and great results mate, really nice pigment too.

Re: Pre-treating paulownia or balsa core

Sounds pretty much exactly what you were hoping for yeah?
Nice work.
It is amazing how sensitive you get to different finished weights after building a few hey. I pick up two boards with 200 grams difference and they feel worlds apart.

Re: Setback sidecut

I've done it quite a few times on boards, swallowtail boards allow you to do it without ending up with a board full of tail. It totally changes to style of riding you need to get the most from the board and I very rarely suggest it on a board I'm building for other people. You need to power into the...

Re: Pre-treating paulownia or balsa core

As Dave has mentioned just give it a coat, then light sand before layup. I have simply brushed resin on before. It will penetrate much less than it does when heated and under pressure of the layup so will work as you need. You need to do both sides at the same time though and cure on its side or it ...

Re: WRONG 2017

Hey guys, I just got given a roll of chopped strand glass because nobody else wanted it. Before I hand it on to whoever wants it I'm just wondering if anybody here has actually used chopped strand in a board before and how did it go?
Layed up with some light uni it might be an interesting result.

Re: First core design ever

Is there a reason you are looking to weaken the core substantially at the point of highest load? I dont see those inserts staying put in that cork for very long. Its a great looking image, difficult to achieve without a cnc and most of it looks more like wank factor to me. Keep it simple at the begi...

Chris, I'll get the specs when I get home from work on Monday. They are both mid-wide boards. Nothing crazy but a little extra float. Heaps of rocker in the nose and a short running length, I think the bigger one is still only a 900mm running length. The sidecut is fairly progressive and the width a...

One is a 160cm board the other is only a 154cm. The shorter one is also a fair bit narrower, this is why the veneers look a little different around the edges, it's just the board dimensions.
