Building A Skateboard In The Classroom

metallica ride the lightning

[ozziejbr97]

so i want to build a longboard similar to the shape of a loaded vanguard and i want concave and camber in it, how can i make or buy a mould

[1234Spazz]

@ozziejbr97 make one using insulation foam

[awesome12345100]

@ozziejbr97 easiest way would be to order a foam thin air press from them, but if youre lookin for something cheap you could just make a ribbed wood press.

[MrReptilesrock]

Does it matter where I get the styrofoam?? I would like to make my own mold, but am wondering if there is a special styrofoam.. Can I just use insulation sheets that I get at home depot??

sup



[zeshybadboy]

I hope that makes sense :L LOL 

[ReeferRappinNRidin]

you really just pressed a skateboard with a bag what

[Steel0Smith]

Her laugh creeps me out.

[zeshybadboy]

@Steel0Smith Too right man

[torrie1107]

he is really good at pumping the air out of the bag =P

[rodneymullenbell]

why dont you just drill the holes after pressing? would save time while gluing up

@katmaiman hahaha

[kbyrd1001]

Hey, can u use 1/8" Baltic Birch in these vaccum bags, or do u have to stick with the veener 1/16" peices?

[freestyle025]

I could spend the materials, please and thank you

[TobiasJohnson69]

how thick are the sheets of wood?

3mm?

[mckinney456]

i didnt get the last joke

[TheBlackBoxKing]

will this deck preform just as good as a board pressed in stages, such as 3, 2, 2,?

[mrkurtcullen]

all 7 layers at once lol its better to do 3 veneers then 2 more then the last 2

[flysnake12]

haha he gave the bag a handjob jk

[boprop7]

where exactly do you get the wood thin enough for that?

[Roarockit]

Roarockit stocks street deck and longboard deck sheets of Canadian hard Maple for building skateboards.

[bwwcpa]

ware can i get the vacume press?

[thirteenfingers]

@bwwcpa

I find it pretty amazing that a company hasn't answered this question in their own YouTube channel... but if you still want a press, have a look on the roarockit website.

Someone else asked about cost - it looks like they weigh in at around $50 to $60 US.

Looks like a decent enough kit to me - I might get one if I decide against a more DIY approach.

[bwwcpa]

cool thanks man

[thirteenfingers]

No problem.

One thing to bear in mind...

Vacum bags like this (or any other) can't draw more than 1 atmosphere - that's just shy of 15psi - so you may not get as good a lamination with one of these as you would with a system that used mechanical, pneumatic or hydraulic pressure instead.

I'm not 100% on how much pressure is needed for a skateboard, so maybe a vacum bag is plenty, but it's something to consider.

One thing's for sure - this is the simplest system I've seen yet.

[rallyboy88]

@thirteenfingers ahh i've read alot of articles and sources sayin that, cuz i was gonna get a big electric driven vacuum pump to do this, but everyones say the max depression is around 14.7psi anyway, still aint got my head around that concept yet haha, gonna go do more research now loll

[thirteenfingers]

Here's how I see it - maybe it'll help:

In a vacum bag, you're using the weight of the entire atmosphere above your workpiece to provide the pressure. Average atmospheric pressure (1 atm) is +/- 15psi.

The most powerful pump on the planet can't draw out any more air than is in the bag to start with, and if you draw it all out - you'll have 1 atmosphere, or 14.7psi pressing down on the bag from above. The only way to go to a higher pressure is to provide more via a press.

That any clearer?

[rallyboy88]

ahhh yes, so i suppose the only advantage of having an externally driven one is speed, but then thats a downer on the electricity bill leaving that on for a few hours everyday lol so unless i get myself an £8000 autoclave, the max pressure exerted is the good old 1 atm, thanks alot anyway mate!

[supersaiyanssoul]

how much does 7 sheets of maple cost?

[SBxxxStudios]

I have found some to make a whole deck for about $15. Maybe $20 at the VERY most.

[danielperson123]

how much is a vaccum press?

[maysguy]

i wonder how good the pop and concave is on the board
