Eye captain. its time to consider a winter evening project.

So.... the carbon bamboo landboard will be built.

Its going to be more freestyle orientated with 9" mbs wheels and intergrated carbon truck housings laminated directly to the dec.

I have everything for the build apart form some DB carbon and some resin.... ..

Oh yes a $10 packing sheet to make a press will also be required.

pss the board will be de-ex geniuos style with no kick. and tucks protuding out the ends.

oooh.... after that i'm mulling over the build of a twin tip. . . . ...

COOL

the bamboo verses the glass core,
will the board end up thicker ? or less carbon
Are you going for a stiffer board or more bounce ?

A good friend is doing a carbon fibre engineering course in about a weeks time,
so I hopping to get him to make a board or two as a class project, as he has already said, he needs a project.
I'm selling a small kite at the mo, so we have another boarder in the making

Only 4mm is a little less temperamental than what I had envisioned and should be fine. When a core is too stiff to vacbag to a table you get into all kinds of nasties unless you add a little extra 'assistance'.

That should be bulletproof tho. I'm a little cautious about integrating the hubs for the trucks - however what's stopping you from lopping them off if they break and bolting on replacements eh? So nothing lost there and uber cool to pull off!

PS. I just scored some lengths of I beams from Jimmy22 over the weekend that I'm very tempted to turn into a press frame.

nice. re the boarder.

i guess it will be about 8mm thick so about the same as carbon glass board. Should have similar properties too.

Not 100% sure of the outcome as i've never worked with bamboo before. but we will find out.

The bamboo i have is about 4mm so it'l be 50/50 bamboo/carbon. i may run another layer of bamboo as a stringer but haven't decided that yet.

my thought process is to;
1 layup a layer of double bias carbon on each side of the bambo press it to shape. prbably max a mechanical press for this.

2 layup the truck housings to each end of the deck individually.vac bag them.

3 lay up the uni carbon as the outer layers. the truck housings should be bonded rock solid to the deck.

I was looking at some sources and this was too solid:

Though the 5-ply is tempting!
www.wovenbamboo.co.nz/bamboo-veneer-g-96.html

You don't have the big kicks in the tips anymore so nothing very radical from a shape point of view. Just a smooth clean curve. Laying up the truck sections will definitely need some thought but not impossible. I was thinking you could make the inside part of the truck with a spline(or wedge) that you can glue to the core in advance. Then laminate the whole thing in one shot with tape wrapping the trucks inbetween the deck layers etc. SOLID!

Are you going to up size the Trucks 50x50 ? I was thinking more 45 Dia 50 wide

Do you need more axles machined , staying with the 16mm 2205 s/s, I have some in stock at a good price

since i'll be running my 9" mbs tyres and standard width axles and not graniies i'll be using the original 40x40 housing id as this is what it was designed for.... not need to over engineer for grannies. Also theres some merrit in running the same size housing for interchangable bushings.

I already have the standard axles from the first build when i had standard and wide made up.

But am interested in titanium. mind you last time i priced that i almost died!

Ti is cool and Evil at the same time, we have a contact but its probably as dear as the whole board. But as light as Alloy and strong as stainless.

price me up some jimmy 16mm x 1m.

last time i priced it, it was $500 per meter and thats just crazy.

Then i'd have to talk real nice to some crazy buggy builder to get the evil stuff machined!... probably far to hard. but wont hurt looking into it.

Was that just cost of material or all machined up? Some outfits double the cost of expensive supplies to cover the cost of mistakes(or customers changing their minds :O)

There is a guy on trademe who sells short sections for much cheaper than that. Think Jimmy got his axle materials from there too. Then you need someone with a large lathe that can do low RPM high feedrate as most of the alloys work harden like crazy if I recall. Then someone crazy enough not to suffer any performance anxiety of ruining expensive parts. I cringe at the cost of acetal never mind the cost of titanium!

i have asked for you Dave, its more likely ill have access to 500mm lengths which shouldnt hurt the project. how long exactly do you need because the might be 300mm long offcuts which may suit you even better.

well standard axle is 410mm. so 500mm would be sweet.

no the $500 was just for the material!!! no machining. eek.

i guess cutting the thread would be the most difficult part.

That is spendy for saving a few grams. Cool, but spendy!

Die or coventry head should be fine for cutting threads. Seeing as it is slightly softer metal despit its tensile strength I might go for a coarser thread.

titanium machines Ok slow with a lot of coolant, just drilling it is a bastard as you can't get the coolant on to it, so it melts like lead onto the drill bit,
Yeah the thread cutting is slow with a lot of Rocol, good luck Guster

I don't think I was the crazy buggy builder Plummet was referring to. My little lathe is way to fast even at it's lowest speed. I am inspecting something a little larger this weekend tho.

beers, cold hard cash ...... i draw the line at foot massages tho!....

I've posted up a request on kitecrowd forum for a pair of TI revo axles. I'f i can find a set and buy em premade the would be ideal.

Also i don't really need TI its itl save me maybe 500grms.if it gets too hard i'll use teh axles i already have.

life is short Ti is worth it , kite deck ones were pretty cheap but hard to come by. the number of time you use your deck id say TI all the way for the CarBAM Board.

"I don't think I was the crazy buggy builder Plummet was referring to "

Well, there's the hot potato back at me

Threading the ends does't scare me the weld the bush / washer in the middle does

I'll have a look at the new lathe. Replacing my 9x20 with a 12x36 which is currently fitted 3 phase. Means I have to either refit the electrics or source a VFD which would give me the low RPM + higher torque for jobs like this. Either way it's not ready soon.

What is the shrink/expansion ratio for Ti. Sounds like a chill+interference fit solution to me!

hmmm.... do i have 5/8 collets for works orbital welder? that'l weld titaniam like theres not tomorrow. might be able to handle the weld portion myself.

any way lets not get too hung up on ti at the mo. i'll build the board and run the normal axles if i thik i need to shed weight then i'll re-visit the TI. theres also the inconvenience of dissimilar metail reaction thats can go on woth ti....

well i've gone off the idea of titanium. now i'm thinking an 2205 axle for dual grannies!!...

then i'll have a normal width axle. wide granny axle and super dune axle.

oh yeah.

"dual grannies!!.."
WOW, like , 8 granny on one board

that's more granny's than , what you can fit in a mini

ps; I have 8 granny's in the shed

yeah the 8 wheeler will be insane. but if it allows me to hoon the dunes the extra weight will be worth it.

hooning the dunes is all about going just after rain or larger diameter wheels diameter does much more than width

yeah i know. but larger diameter poses more problems so the dual granny will be tried. if it doesn't work then all i loose is the axle cost as i need to get another set of granny tyres as mine are wearing thin.

How many grannies? Now there's a picture to replace the one of NorthernAl in a buggy hanging of the back of a van.

Yea...tried some 300mm wheels on a mountain board and it wasn't great. Even flipped the channel trucks to the top of the deck to lower it. Works on a three wheeler board though. Maybe in a quadrilution set-up...

PS. lost some brownie points this weekend when I took time out to clean my lathe for a photo-op with trademe. Came about after inspecting something on Saturday and accepting an offer I couldn't turn away.

well i haven' found suitable dune landboard wheels yet. so 8 wheeler will be tried. and having those extra granny tires will give me 2 granable landboards for the next 24hr attempt.........

so this intergrated truck board will be se a little higher with grannies on soit wont be too low when i jimmy th e9" tyres for a freestyle session.

dave do you recall the video where those lads are using yellow plastic balloon wheels and bombing down the dunes ? i think if you can go down that well you can likely go up too , its more the shape than the wheel type that im thinking of...

yes i have and they are called wheeleze or something similar. i've checked those wheels out. tho they are light and big they are more like the construction of an inner tube. they may work well underpowered on soft sand but wont cut it against the side pull of a well powered kite. I want to huck off those dunes and glide down.... need to be powered.

Jimmy is right. Those Yellow Wheeleez are the only thing that will do the dune landboard. Edging hard & holding power to boost off the dunes is going to be difficult with a big tyre like that. I think the fact you will be riding dunes is enough to start with.

The Wheeleez come with nylon bushes instead of bearings. High speed bearings can be purchased from them at $50US each. I have plans to get a set but they are mega expensive from the US and if they dont work, well, a waste of money.
Good luck with the Freestyle board bro!!

www.wheeleez.com/beach-wheels-polyurethane.php#WZ130U

There's the wheeleez wheels.

its about $500 to test the theory...... plus axle. too much for this white man.

those look about right hmm side force , point taken .

maybe no wheels like this guy

the old flysurfer as a backwards paraglider trick aye? looks sweet. but at the same time there could be some death if you stuffed it up.

I have also thought about wheel less board. but that is also not going to work very well.

I either pony for wheeleez or trial a dual granny. taking into account i can already ride the soft on the grannies. but its HARD work and you can't really stay upwind. i think a little more bouyancy will tip the scales and allow better soft sanding. so i'm still keen for a dual granny trial. or maybe a 6 wheeler? dual toeside edge and single inner?

instead of spreading the load out sideways what about lenthways.

o====o====o


ie a set of wheels between your feet if thers space...that would move the weight away from the outside and it would roll in a set of grooves already cut by the front wheels proving less drag for more float....this i think is the best bonus of lenthway setup
but i know itl stuff up your flex
but it would also improve your powerholding capacity due to cutting an entirley new groove for itsself if you are drifting...
should also be pretty easy to build..i

AND then if you really wanted to go monster you could run a full 6 grannys, just to make sure!!!!

What about the idea we had to use some gokart tyres on plastic hubs. Remember that trademe listing with the second hand tyres?

yes gocart and plastic hubs i'd forgot about that..... 6 wheel catapiller board... it so crazy it might work....

ideas ideas.... hmmm.

sounds cool , how would the middle trucks move any ideas ?

my instant thought is that they would be fixed like trailor wheels. or perhaps have a limited caster but its a pretty hard design. easier to just slap bigger wheels on the existing trucks.

gokart wheels and plastic hub is getting me thinking down that track again.

yep....wind power





its a loadbearing pivot, but nothing more...it only has to rock back an forth with the board, just a follower...so id put it on a couple of bearings inline with the board and bolt it down...thats all it has to do.

can to get another truck and bolt it to the middle of the board?

Dirtsurfer with Kenda beach racers!

thought of that too.....but at the end of the day i'm at dunes maybe 3 times a year. so don't want a specific dune board. its more ideal to have some wheels/axle i can slap on an existing deck for some dune action rather than a monster piece of equipment that gets used so little.

ps and thats why i don't have a buggy.....

"Dirtsurfer with Kenda beach racers!"

Like this, but this one is a sit down model

"ps and thats why i don't have a buggy...."

sounds like, buggy Denile . We know you want one, stop fighting it

Of course i want one. i'm a closet buggier. i do silly things like go fast, circuit races and long distances plus i hnuker for the dunes. But there's no dunes or high speed beach or circuit races around here. So i can't justify the expense. plus all my gear fits in the boot of my car which is very convenient. it means it can lie in wait for any moment that presents its self.

One day i'll step up. but each time i look at a new man toy aquisition. theres always something else higher on the list that i will use more often than a buggy.

Of course if anyone is just giving away fully stacked buggies i'd hate to see them in get into the wrong hands. Send em my way!

nothing wrong with the land board mate. Im just looking forward to see what sort of buggy you make when you get round to it.

Say no more...

um..... yeah.... ahhh. how about no!

The Gannetworx factory was busy today, open from 9am to 10pm, and a lot of new toys to go on show at the BBBB
+ some kiters getting there hands dirty
