I have some cork that comes on a roll and it looks like it would be a pretty comfortable no skid patch…could glue it down with contact cement. Am I out of my mind? How about a board made of cork?

How about a board made of cork?>>>>>>>>>>>>cork? hum,the problem is cork will take on water like foam after long periods of submersion in water,and where the hell are you going to find that much cork?Interesting though>>>>>>>>>>>>Let you in on another one of my Crafty secrets.Go to Ikea and get this knobby ,clear ,soft , plastic drawer sheeting(I have some in a roll in my shop if you really want the name and codes of it ,I will do that for you).It comes in a 6’x I believe 24" sheet rolled up .Just spray glue it with 3M Spray 90, not 77.You can also ruff up the surface once and awhile,but it’s not a ness.>>>>>>>>>>I also make my own sanding pads ,and have done so for over 7 years.I use the plastic sheet for some of my pad surfaces,I call it the agressor surface.Herb
Thanks herb.I kinda posted the cork thing rather quickly but started thinking about it more. I am doing a search on cork right now this stuff comes in sheets ,dimensional and on and on.I’m computer kook so I kinda get lost in these searches …why don’t you check it out. A A truly organic surfboard…far out man!
Everyone makes there own hand pads from the start.Herb
I need more cork for my throwing knive board,anyway.Herb

A A truly > organic surfboard…far out man! Hey, Cleanlines, I definitely remember reading about some old surfboards made entirely of cork in another country… many years ago in a surfing magazine. I believe they were successfully fiberglassed, too. Cork has some fascinating properties applicable to surfboard building: “CORK: Cork* comes from the bark of Cork Oak trees (Quercus suber), which are grown mainly in Algeria, Spain, Portugal and other parts of the Mediterranean. It is actually an elastic, homogenous mass of flattened dead cells combined with a fatty substance which makes it almost impermeable to moisture and gases. About every 8-10 years, the bark can be carefully stripped from the trees without injuring them. Cork trees in fact live about 150 years despite the periodical harvesting. The best, close-grained cork comes from the more mature trees. During processing, the stripped bark is briefly seasoned and then boiled to make it spongy and pliable. Cork is great for wine bottle stoppers and has been used for this purpose since glass was popularised in the 16th century. Nowadays, synthetic stoppering materials are beginning to make inroads on its dominance, due in part to a steady increase in its price on the world market. Cork’s flotation properties have seen it used for fishing floats and lifebelts, etc, for many years as well. It also found favour for a time as shoe insoles, but again has been largely superseded by high-tech urethane foams, ‘gels’, and plastics. Cork is still in demand for noticeboards and pottery bungs, however. In building, cork is best known as a great flooring material - in tiles and sheets or in lino - due to its slight springiness underfoot. It has a natural honeycomb structure because of the cavities formed during its growth on the tree. These air-pockets allow it to slightly ‘give’ when pressure is applied and also give it excellent heat and sound insulating properties (in the U.S., it is sold as ceiling insulation, with an ‘R’ value of 3.45 per 3 cm). Homemakers have tended to favour cork as much as synthetic alternatives because of its natural character and appeal. (For suppliers and installers of cork, look in your local Yellow Pages under ‘Cork Merchants’ and ‘Floor Coverings’.) *‘Cork’ can refer to any light and porous or soft and spongy tree bark; such species as Erythrina vespertilio, and Duboisia can also be considered to be ‘corkwoods’.” http://www.rainforestjukebox.org/good_wood/nont_bld.htm#anchor539525 http://www.expanko.com/ http://mantoncork.com/

Hey maybe you wouldn’t even have to glass it…just apply a coat of linear urethane,epoxy,acrylic or something along that line.This stuff is really durable.Do you think you could get some numbers as to the weight factor…as related to say foam or balsa?
Cleanlines, These guys will be able to answer those types of questions and give estimates on grades of cork, availablity and cost: http://mantoncork.com/rfq2.htm Dale
Dale…that was a cool post. thanks for the info. Wonder if da portagees are whipping up some cork boards as we speak?

I will have to laminate them like balsa. Do you think white glue will work or should I be safe and use something more high teck? I bet that this stuff will be pain to shape but I have a grit drum in one my planers…Am I insane??? Anyone know how find Corky Caroll? Hey Dale as Luthier you may know my old buddy Randy Wood?

Cleanlines, What a great project! 36 grit should do it, and try using a right angle high speed grinder as you would on polyethelene bodyboard foam. Id definitely use a good grade of epoxy (as for EPS foam), both for adhesion and also because with epoxy, you can take advantage of cork
s great impact resiliency. Be sure to document your steps and discoveries along the way so you can share what youve learned! Sorry, but I don
t know Randy… I`ve been away from the luthier world for quite a few years. Dale

What does Clark use to glue up blanks? If it’s polyester I don’t think it will hold. What about the old time powdered resin glue? I think that the grit on this drum is around 36 or 40…these things are unreal.Again…thanks for your time.
what about an adhesive like ‘liquid nails’ to glue up the cork blank. it’s the stuff they use to put wood paneling on walls with. it think it’s got a caramel-like color that sounds ideal, and sticks like a mutha. you’ll glue up the blank with a wood stringer, right? this idea of a laminated cork-core surfboard is really intriguing! if you can do the rough shaping with heavy grit adhesives, and then get a smooth surface with a fine grit finish sanding, it’s gotta be a spectacular looking board. wow. good luck!
