Some advise please

[Brodie]

Hey guru's,

I am well into my Mountainboarding. I want to make myself a deck for use on a mountainboard.

Ideally it will be very light and very stiff. Also impact resistant......

Can anyone suggest a good construction that will give me these properties?

What sort of composites should I be using?

All help gratefully recieved.

did you read that sticky on board building?

[Brodie]

Yes I have been browsing this forum for a month or so now......

I could not find anything relevant to this in any of the sticky posts or the search feature....

I am sorry if I have missed something.

Can someone be a bit more helpfull than that please?

Mountain/off-road boards get chewed up pretty badly.
Tough, flexible, moderately heavy boards usually do better than light stiff boards because the stresses from the uneven surfaces, impacts and oversize gear deliver more of a beating.
If you have looked at a generic flexifoil flat board, it is usually a bit to flexi but otherwise a durable chunk.
What seems to work best construction wise is a multiple layup of maple with biax glass sandwiched under the top and bottom layer. The stack is glued up using epoxy.
A maple board with a bit of concave in conjunction with the biax provides a spring-back component that rebounds from impacts, takes a fair beating, provides plenty of strength to add heavy duty gear and is an economical design to start with.

Ok so you are saying:

Maple-Glass-Maple

That dont seem to hard......

Fully wrapped kevlar on the bottom and rails should help with the impact-resistance.

i think he ment more like maple-glass-maple-maple-maple-maple-maple-maple-glass-maple

i might even do some kevlar on the bottom for show and extra wear resistance

I opened up an old knackered MBS comp16 deck....

....What I found scared me.

IT has a wood core. A really cheap wood core. No plys just a horrible looking chunk of wood.

This has been covered in some other material, either CF or FG or similar.

I am now convinced I can make something better than this.

It does need to have a lot of pop though.

FYI,
endgrain balsa core could probly be mistaken as a "horrible looking chunk of wood", when in truth it is a very viable core material. how does this chunk of wood feel? and how thick is it? can you see grain in it at all?

[Brodie]

Yeah it could be Balsa, big fat grain and very soft wood. Its about 3/4" thick.
