Who has used bamboo stringers?

I’d like to hear from anyone that has used bamboo stringers. Provide as much detail as possible. I know Greenlight is/has offered them, but I am very surprised we haven’t seen a huge move toward their availability.

With bambo being a highly renewable resource, 16% harder than maple and something like 33% lighter than oak, and inherently beautiful with many species to choose from, what is the hold up or reason we don’t see a flood of available options?

The more information available the better, including cost, flexural characteritics, abilty to bond to polyester and epoxy resins, blunting considerations to planer blades and other tools, and of course, any drawbacks that have been experienced with the material tried. If you know the genus of the bamboo, all the better.

Thanks in advance…

I had one made at Greenlight. Works great as stringer material. I used it on a 9’ EPS “performance” longboard. The board works great, but I don’t know how much of a factor the stringer is since I don’t ride it much. Be VERY careful handling the stuff. It makes these tiny splinters that get in you if you’re not careful running your hands/fingers along the edges. It wasn’t so much a problem for me when shaping, more in the gluing up stage. You can get the stuff in CA at a place called Cali Bamboo. http://calibamboo.com/bambooplywood.html?gclid=CMfq84jwxYwCFRAjhgod4ECvVw There’s some 1/4" material in 2’x8’ and 4’x8’ sheets. Problem is, unless you’re doing 'em in volume or can split an order with someone, it’s a little pricey as they have a five sheet minimum order.

Surfthis…thanks for your quick reply…unfortunately in the real world or production this isn’t remotely viable to offer in existing rpoduct line.

I’m still curious who will step up to the plate and offer bamboo stringers while so many blank comanies are vying for position in the current marketplace.

Should bamboo be expensive?

I really don’t believe it should as some bamboo genus (geni?) are capable of two feet of growth per day, or something very close to that…seems unbelievable but I saw something reported to this effect. Try finiding a redwood (even the new reengineered redwoods, which are reportedly inferior to old growth redwoods), bass, poplar, cedar or spruce that grows at this rate.

Much of the scaffolding used in Asis is built of bamboo, which attests to its strength and current pracitcal use. Do you think those guys would be climbing around at insane heights if they didn’t trust the integrity of it?

C’mon foamers…wake up, where are you?

Gary Young has a web site i think he was around SB anyway probably could give you all the answers you need. Aloha…

After having hard time to find some red cedar to make a stringer, I thought about bamboo as a stringer material reading durbs post about his nice compsand.

He bought his bamboo venneers there http://www.franksupply.com/specialty_products.htm

The bamboo panels look quite cheap and should be ok to make stringers, I might try that this week-end, I’ll post some infos.

Is bamboo really green from an eco perspective? In order to bind the product into a usable board a lot of non environmentally friendly glues are applied. At least with wood you know what you are getting. I would be cautious about breathing in any of the sanding dust from bamboo boards. If you just care about how fast the plant is able to regenerate then stick with Balsa wood. Balsa is a very fast growing tree.

All of the Greenlight blanks have bamboo stringers. The price issue may be because you have actually make the bamboo board, rather than just ripping a tree into whatever size lumber you want.

Swied…I think you would have to substantiate your claim on that one…bamboo flooring is now widely available in the flooring industry and doesn’t seem to pose much problem affixing to any variety of substrates. I doubt that bamboo is a huge task to produce and put into blanks, and the comment after your post here states that Greenlight blanks come standard with bamboo. As far as the difficulty in making it into board thereby justifying expense compared to conventional woods I would cite the cost of bamboo flooring compared to oak, cherry, walnut, and other woods.

The arguments against bamboo don’t hold up. The resource is massively available and regenerates like no other. So unless someone can really step up and state that there is some unsurmountable or unforseen problem with the use of it in surfboards, I would say that he few people that are really involved with it are light years ahead.

I think it was Gary Young that Eastern Pacific sent info to me on and I elieve he is now on the Big Island…and his stuff is waaaaay way ahead of anyone.

Oh! I forgot to add…as far as shaping balsa as a preference over bamboo…just TRY shaping balsa without a really good mask and wait until the wood dust swells inside your moist lungs.

I don’t have any facts to provide. All I’m saying is that bamboo – like plywood – is a manufactured product. I was in Home Depot the other day looking at plywood, and saw a warning sticker on the wood that said “This product contains chemicals known by the state of California to cause cancer.” I don’t know anything about any of the bamboo manufacturers, and what chemicals they use. All I’m saying is that bamboo isn’t necesarily that green of a product. Maybe if they put a sticker on their boxes stating that no bad chemicals were used in the manufacturing process, then it would assure me that I was actually doing a good thing enviromentally by purchasing the product. Don’t ge me wrong. I still use plywood, and don’t have anything against bamboo. I just am not convinced yet that bamboo is the answer to our environmental problems. I’m just thinking down the road. Would you rather put an old piece of wood into the landfill or a bunch of chemical laiden manufactured wood products like bamboo and plywood? I think that we really need to focus on reducing our consumption, and making products that last longer.

I see and respect were you’re coming from. There is a heightened sense of awareness of issues like the cabon footprint created getting something to market, as well as the actual makeup of widely used and accepted products.

To be quite honest, the unfortunate part of our society that broadcasts news and affects our collective conciousness tends to dwell on the negative. The news at night and the newspapers generally report the news from a pretty limited perspective.

In actuality there is a ton of positive stuff that is currently exploding in science, technology and the burgeoning environmental and recycling industries. It’s happening everywhere around us and yet you hear very little about it in the mainstream. I don’t know why that is nor why it has to be that way.

Perhaps part of it is where our priorities are positioned. Maybe another part of it is that we need to rethink what should be profitable. It really shouldn’t be a stretch of the imagination to reward man’s feats that benefit the general good.

Without getting too abstract, we need to be reminded by Shakespeare that “nothing is good nor bad, thinking merely makes it so”. Sure, that’s debateable, but the entirety of something is rarely 100% good or bad. Such is the case with new approaches to what we do.

In the case of surfboards, I can tell you from personal experience that the resins, paints and coatings of yesteryear were far more harmful to your person and environment than they are today. There are enough of us on Sway’s that still remember the pains we went through as the materials we had grown so used to became subject to scrutinization, than legislated change threw us into having to adapt to what was an environmentally more sound product. There was plenty of cursing in the back rooms of surfboard and boat factories, believe me.

I don’t think bamboo needs to be subjected to processing like (OSB) Oriented Strand Board or particle board or some of the other rather nasty materials that go into your living room sofa that will kill you from the vapor if the fire doesn’t get you.

The only reason I think we are even having this conversation is because we are at a starting point for thinking outside of our usual box. Not unlike what a few of us were doing with Kevlar, Spectra, and Carbon Fiber back in the 80’s. But unlike these wonderful synthetics, bamboo has very promising natural dynamics yet to be realized. The longitudinal strands that make up bamboo is inherently well suited to surfboard stringer application. it would be self defeating to grind this stuff up and apply a toxic adhesive to it rather than leave that dynamic as much intact as possible.

In this era of post Clark blank manufacturing, a key focus has been placed on flexural characteritics and how that affects the ride of what we build. Bamboo is promising partner waiting in the wings yet to be called on stage.

I can’t wait to see what we get once the play starts!

I think this is a good discussion. My questions about bamboo are just things that I have been pondering. I’m sure others have the same thoughts. I would like to get educated on the real benefits of bamboo wood products. I’m sure that some producers are better than other. I have seen some bamboo wood flooring, and they look very nice. I remember that someone posted a link here on Sways a while back of a sweet looking bamboo HWS.

I don’t know if you have seen this one yet. Here’s a funny article about a recycled bamboo water craft…

I was in Home Depot the other day looking at plywood, and saw a warning sticker on the wood that said “This product contains chemicals known by the state of California to cause cancer.” I don’t know anything about any of the bamboo manufacturers, and what chemicals they use.

I believe there’s formaldahyde in many imported bamboo products.

Standard wood products are simply sawed. Raw bamboo needs much more additional processing to be made into boards, plywood sheets etc etc.

Then there is the issue of Chinese made bamboo products. Quality/Reg controls are lax and there’s a lot of cheating too. Remember the lead toy paint thing a while back? Those guys got caught. For every one that gets caught, there’s many more that dont.

You also have to remember that for everyone that cheats there are many more who don’t.

True, until there’s more easy money to be made by cheating.

Btw, the business man responsible for the lead paint was found hanging dead from a rope.

Yeh, most of the onus is on the American (or other country) importer/business who is ordering the product and selling it in their own country. For the most part the Chinese will make you what you want. If you want cheap crap they will make it for you, but they can also make some quality stuff (if you demand it).

OB has a good point…there are some phenomenal products coming out of China along with the mediocre and substandard stuff by our standards.

China is very much into giving the world what they want…whether it is environmentally friendly or not. Is teir country polluted? Absolutely. Many of the Chinese people are mortified by the situation and it is generally regarded as a crisis. I read that there are more solar water heaters in China than the United States.

While it has been stated that California has the toughest standards on air quality of anywhere in the world, I am sure some people would like to debate that. It used to be that people felt New Zealand was the cleanest country in the world by far. Actually they have their fair share of crud too.

I don’t know how many people have died as a direct result of formaldehyde…were’s our statistician (sp?)…? As far as the cancer thng…geez, breathing, eating living causes cancer…get the stem cell programs going and wipe that tear away. Maybe you where smoking for 20 years befre you did that one bamboo board, and you have a high fat diet, and you drink too much…did the board give you cancer? I’m not trying to dismiss cause for concern, I’m just saying…living has its inherent risks!

“This product contains chemicals known by the state of California to cause cancer.”


I see that same warning every time I put gas in my car. Over the years, I’ve put a lot of gas in my car. Heck, I used to work in gas station.

Yes…cancer producers everywhere…did dioxins release in the plastic veggie steamer you just nuked in your microwave? What about refilling plastic water bottles? Did you drink from your garden hose outside? What about the charcoal on your steak that you BBQ’d?

The challenge that man has is formidable, but in looking further I was able to glean some more information about bamboo coming to America (and other nations of course). Imports of bamboo products now top $2.6 billion.

Yes bamboo is very sustainable with the growth rate stated in different sources from 1 foot per day to others stating nearly 2 ft…it’s fast in either case, and it is harvestable in 5 year cycles versus wood trees that require 40 to 120 years. Ironically it is calculated that less diesel is used to ship the wood harvested in the U.S. to China than it is to truck it to the west. Imagine that.

To process bamboo into woven material sodium hydroxide is used (one of the main ingredients in Drano) and carbon disulfide. Both are volatile organic compounds. If made into rayon the water waste has particularly nasty stuff in it and isn’t yet commonly reclaimed.

Flooring as well as other products may not be pesticide free as companies desire increased yields.

Eco Timber, a company whose accounts include Darpeteria and Environmental Home Centers guarantee sustainable harvest,and use adhesive that doesn’t outgas formaldehyde.

Two green building rsource centers are Green Building Exchange in Redwood City CA, and Nexus, located in Boston.

But the industry definitely needs oversight, and using a 3rd party certification akin to organic labels is highly recommended by concerned parties. A good choice might be the Forest Stewardship Council which has provided services worldwide for over 13 years. In 2004 FSC developed strict guidelines for the bamboo industry. To date only oone Malaysian based company has signed up.

Back to the subject at hand, wooden stringers, would it not be even better to remove the flexural unknown of the wood from the board altogether and supplement the foam with more glass with more consistent standards?

I’ve been riding some boards in the past year made of different materials (Biofoam, Ice-9, EPS, stringerless EPS) and have to say out of all the variations, I like the stringerless EPS the best for a variety of reasons. One for the overall simplicity, it’s just down to the basic elements, but also because it removes the weight of the stringer and allows you to add that weight back into the outer shell where it’s more needed.

Just a thought to mix things up. Bamboo IS great stuff though, have solid bamboo floors throughout my house and you’re right, the price was half of that of solid hardwoods. I may use some of the leftovers to make some fins out of but will need to glue them up into usable panels first.

If you look up a previous thread I did or was in I talked about stringerless EPS longboards and how I glassed them using staggered laps of warp cloth. These were very high performance stinger longboards 9 ft. long weighing 9.6 lbs. that are ridden by a team rider in heavy duty conditions north of San Francisco. The thread discusses my glassing schedule and related concepts.
