Neighbor gave me a Homeblown Bio Foam Blank...

Since its free, I’m experimenting with it (made a shape on shape 3d and getting it cut on a machine)

Been hearing rumblings about issues…

How should I get it glassed - EPS or Poly? Bashams is going to do the glassing

What about fin boxes? FCS vs. Future vs. glass ons?

 

you can’t glass it with EPS… EPS is a kind of foam…

Only issue I ever had with those was that they yellow to almost a light brown when exposed to sunlight… so plan accordingly.  Paint the blank or use pigmented resin if you don’t want a board that’s the color of a cup of tea…

Use whatever fin or fins system you like.  The blank won’t care.

 

Oh man… that almost made me pee it was so funny

Any chance your neighbor wants to share how he blew his own blank at home? Kinda curious - he must have a damn cheap way if you got the blank for free considering spray-foams are pretty expensive as it is, and bio-materials are typically so much more expensive, that companies typically take payment in the forms of blood, firstborn children, and human souls

Depends on what u want, if the money is not a problem do it with epoxy.

About the fin sistem… i am a fcs fan, what about u?

Lol… had EPS blank in my mind and typed it

 

In regards to the boxes, I’ve heard the biofoam blanks can shrink up to an 1/8 of an inch. Do I risk it?

I wouldn’t hesitate to use fin boxes… probably its already shrunk as much as its going to, if that was a problem.  Its not an EPS blank, so as far as I know you can use either kind of resin to glass it.

To shushka420: Homeblown is a company blowing foam in the UK, they used to have a us distributor but im not sure any more. The bioblanks were made from Soy based products if i remember rightly, they arnt making any more though due to their “sustainable” source not being so sustainable.

To Grendel: I have a few of these in my blank rack just chilling, ive found they are lighter, the foam is much easier to carve down than normal homeblown/us blanks and xtra foam. Ive had no problems with plugs or boxes personally but ive only got 3 bios in my quiver now. As to their word that its stronger: it isnt. A friend did his dissertation on foam types and it did not win any awards. From personal experience, id say check  the stringers straight but i guess this wont be a problem if youre machine shaping it.

Only one of mine has any untinted foam showing, a mini simmons i made for myself at the start of the summer. After a season of surfing and sitting in the garden uncovered, its now got some… interesting foam colour, creamy bits, brown swirls, but mainly just looks yellowed. If thats a big deal for you, paint the foam or do a coloured glass job like keith said. Sadly my pics are of the bottom but you can see the yellowing through the swirl…

Then…

Thanks for the info! Machine shape and finish shape came out well.

Foam is yellow brown with white tiger stripes, pretty groovy looking but I’m gonna have it painted.

Sweeeeeet, glad it machine shaped well, i found it to be very crisp and shaped beautifully. Just a shame the strength isnt there in mine, id give it at least a twin 6 deck but thats personal preference, im tough on my boards. I was stoked on the stripes in the deck of mine, opposite to yours with white foam and two big brown streaks nose to tail

Double post… oops… heres a pic of my stripes (sorry for the minor hi-jack)

Free is good.  Otherwise an inferior foam.  If he could of kept it going longer the foam might have improved,

after its shaped it shrinks back its best to leave it for a bit too see what it does ! its weird also as said stringers can be bad or twist as well as the whole blank

i glassed a bottom and the whole tail pulled up the opposite way to the rocker !!

and yes its weak an delams so i would epoxy

 

Hahaha… okay my bad - I thought “homeblown” as in he made the blank in his garage

Don’t feel bad,  At first I thought this thread was about “homegrown” of the type that is smoked.

Oh man, I can see that thread now:

“I mixed a bunch of roaches with some ash and pour foam to make the blank, then glassed with hemp fabric/bong resin - oh yeah, and the logos are printed on some zig-zags”

Got it back from the glasser…rides well and no shrinkage/swell (yet).

 

I'm not "green".....I'm Blue!

...won a blank in a Swaylock's Big Sur Raffle....oh wait...maybe I scored a blank in late night drunken trading........

....looks a lot like your board....but blue pigment to hide the corn colored foam.........there's a ride thread somewhere....

here's a link to some Swaylock's photos......

I’ve still got a biofoam board that’s going strong after 3 or 4 years. Homeblown are just down the road and there’s a few guys locally with biofoam boards (mostly homemade). They had a pretty fair product by the end and I think if they’d kept it going, and people were willing to accept straw coloured boards it’d have had a place. I remember talking to Tris about it before they stopped and he reckoned they got it lighter and stronger than their white blanks.
