Balsa wood help needed

My supplier went into making surf boards and I'm not having much luck finding 1/2" x 4" x 36" x hard balsa on the net.
Anybody know a dependable supplier?
Thanks a bunch!

I just purchased a large order of Heavy Density Balsa from SpecializedBalsa & was satisfied with the service. They charge an extra 40% for the Heavy Density, but I think it is worth it. It really sands much smoother than light "Hobby Shop" Balsa.

Send a PM to Stripercrazy and see where he purchased his from. It was over 20lb p/cubic ft. He sent me a sample and it was too hard for me to want to work with.
If you like hard balsa you might want to try Paulownia wood.
The density of Paulownia is a consistent 15lb-19lb p/cubic ft. Slow growth trees weigh a little more and fast growth trees weigh a little less. The fast growth trees might have up to 2 inches between some of the rings. The feature I like best about it is the weight of the wood being so consistent from one end of the board to the other. I have weighed identical cuts form the same board of Balsa, no more than a foot apart and one piece might weigh 1.8g and the other might weigh 3.1g. When I have done the same test with Paulownia the difference in weight is much less.
Here is a little information on the wood. Two cut and paste from other web sites.
Paulownia is about 2/3 the weight of the lightest commercial wood grown in the US. Average cubic foot weight varies between 15 to 19. This falls between Balsa wood and Poplar. Paulownia is 1/3 the weight of Oak (44 lbs p/cubic ft) and half the weight of Pine (30 lbs p/cubic ft).
The specific gravity of Paulownia ranges between 0.23 to 0.30 (23 to 30% of the density of water).
Balsa has been considered to have the highest strength to weight ratios of any wood in the world. Paulownia has been tested to have a higher strength to weight ratio than Balsa. Auburn University tested the strength of 18 lb p/cubic ft. against Balsa, with an average weight of 10 lbs p/cubic foot. (See Table 1)
Paulownia holds nails and screws well and does not require pilot holes to be drilled. In fact both yellow poplar and white pine have proven to split before Paulownia. Flat head screws can be driven flush with the surface.
Plantation grown Paulownia is mostly knot free.
PHYSICAL PROPERTIES OF PAULOWNIA.

Excellent information Palmetto.
You should consider a handle change to Palmetto Paulownia!

I also thank you for the information, Palmetto. Things are clearer in my mind as far as this wood is concerned. Think I begin to like it more.
But I don't think you should consider a nickname change, as Vman suggested (). We are all very used to the the one you have now.
For those who like rattles in their crankbaits: if my hearing is good, I think that a rattle is noisier in Paulownia wood, than in other types of wood.

i will never use it and rather trade for some eyes or some other plugbuilding supplys.
i build salt water stuff so every thing is on a larger scale for me.

Thanks ya-all, I almost ordered from specializedbalsa till it came to the $13 shipping fee no matter what you order. (Charge me more for the Balsa and I wouldn't feel raped by the shipping)
I may have to bite the bullet and use them as there's not much else out there. Thanks again for the reply's.

the reason for the high shipping charge is due to the packaging used by them, your items will not arrive cracked or dented, been using them for 6 years and never an issue!!

The balsa I have is very light grade and is much too soft. It was my first balsa purchase and it's lasting a looong time I like paulownia very much except it does have occasional "grain issues" - narrow dark soft porous stripes, sometimes adjacent to very light hard grain. So sanding can be tough and I sometimes have to work wood filler into the black grain to prevent it from cratering. But it is surprisingly tough and hard for its light 18 lbs/cu ft density and it makes very durable baits.

Thanks everybody. I'll bite the bullet on the shipping.
