CORKER V MACHINE

General Discussion

Aloha vaccuum baggers,

Corker V Machine(CVM) is not a design concept, but a technique.

Not to be confused with Stroker V Machine because my V is actually a roman numeral 5 and not the abbreviation for versus.

The one string on my guitar for the past 25 five years has been balsa wood veenering. I am now referring to those days as  BIVM(Balsa, roman numeral 4, machine) techniques.

Balsa and a few other species of wood has served me well over the years. I still love to make these boards too. But it seems I now have graduated to a second string on my guitar and 

it is becoming the go to option more and more.

I am totally amazed by this corecork stuff.( I am not compensated in any way by corecork, and I am not pushing my product here either). My build times literally are 60% quicker with corecork. If the difficulty with using balsa for total skinning of a board, rails and all, is a 5 on the difficulty scale of 10, Corecork is a 1 for me. 

Difficult contour shape, wings and bumps on boards are EASY with corecork.  Relief cuts are needed less frequently and when used seamlessly blend. I can’t appreciate the seams any more.

Cost: Corecork is inexpensive. I pay a bit more for shipping to Hawaii, but the value added in durability, quicker build times, makes this product worth while for vacuum baggers.

You might ask if there is a down side to corecork? For me, balsa  was a forgiving covering that you could correct minor shaping errors on the foam with the skinning in balsa(pukas, nicks, gouges). CoreCork follows the true shape of the blank to include any minor inperfections on the blank to be skinned. I realized this on one board and easily fixed it with a seamless cork patch and now make the blank perfect prior to corecork skinning. This may not be an issue for any of you shapers, but for me I had to adjust.

Another down side could be aesthetics. Full brown is not everyones cup of tea. But as seen on Drewtang’s posts, his colorwork and CF/kevlar rail work are amazingly beautiful. I am personally not great with color work, pinstriping and such. I must now get better at these skills. 

My latest board was going to be a pin striped outline just to break it up. But the balsa rails came out so nice it formed a natural color contrast pin line.

Attached photos of a Corker V Machine technique after final coat of FH epoxy. Awaiting sanding and polishing.

Soon I will be trying exposed corecork decks to see what that is all about.

Props to drewtang for initially making my mind want to try this amazing product.

Corecork might be a great material to use from a composite perspective, but it sure makes one ugly surfboard! I know some people are saying bamboo is so 3-4 years ago, but it’s much more aesthetically pleasing.

When I see bamboo I automatically think “china made”. Also you can’t wrap rails with bamboo.  Not sure how bamboo is supplied also. The corecork comes in a 4 foot high roll that is so out of the way in my shop.

In my limitied research with corecork, it has a long standing use in canoes and kayaks also and a major windsurfing/SUP manufacturer is using cork also. It is hidden with paint usually and some leave a small naked window to show the cork. 

like you say, the composite benefits are amazing and all those points I mentioned too. As far as looks, it is easy to pretty up and someday maybe I will get good at that.

Hey Huie,

 I imagine you will find it simple to use and benefit from. My sample piece looked like that on one side too. My first or second board I was sanding the rail and came to the green dye while working on  the non dyed side. The 4’ rolls had less printing on it and I never had any problems again. It seemed the mark was at the center and I was always not using that piece.

aloha

nah mate i have a full roll its stamped all over but thats under i dont think its going to bother me’’

a day or so and i will know a lot more. i dont need to tell you there is endless ways to go with this

im keen to go glass less. and mostly nylon under pending what i am trying to do

its the most green product being offered that will do the job.

 

 cheers huie

I use to be a cork floor layer way back in the 80's and have always been a fan of cork, I just never imagined to going to surfboards.  I find this to be very exciting to see this happening and can wait to how this devolops and one day in the future trying this myself.

Merry Christmas and Happy New Year to you and your family!

 

Are you doing solid balsa rails now or is that just a wrap?

Also is core cork cheaper than those balsa strips we used to buy from the mainland?

and if you are glassing over the top of the core cork skin how is its resin asorbtion, is it like divinycel/corecell or less?

I think its a great idea and an exposed cork surface seems like the next great “sufflight-like” no wax skin…

I wonder is Jim Richardson is thinking of bagging these over his polpropylene/carbon fiber xps cores versus spraying on that boogie board urethane stuff.

also maybe George at PlusOne can bag/skin this new ifoam core with this cork which would be an interesting long lasting combo.

 

take care

Hey Bernie,

 Happy New year to you also…

I wrap and can do balsa rails. Just wanted to add some width to the board. I was going to pin stripe it but it cam out too nice.

I use the corecork just like it was balsa, except it is quicker, easier, less expensive, stores easier. I am using the very small amounts of resin and the glassing of the outside is same or less resin with the NL-20 density compared to balsa, wayyyyy less than HD foam(corcell, divinycell). 

I really haven’t considered doing exposed cork until I saw drewtang’s posts. After seeing the tricked out rail and glass transition to the exposed cork, I initially felt like a hack of a builder in comparison. Definately giong to try it soon.

aloha,

 ** haa’’ strike one to you’’    i soon enough found that out  the cork i got has that green shit all over it**

  good job i still have my eye in for pin lines

 

cheers huie

Yup Drews fault,

Cork makes me laugh every time I pull it out of the bag ----- so easy, argh bamboo sucks in more ways than one. I took the exposed cork LB out for a test run today. It is interesting.

PS: I like the shape of your Corker V Machine!

Lava,

You have raised the bar agian.

aloha,

Charlie

Check Please.

 

Hmmmmm, not sure how to one up Huie’s boards and those diverse. 

Vacuum bag core cork to my upper front torso and bottoms of feet…leave it bare, forever traction?
