Awesome stuff
4 years ago
The way they shipped it caused it to crack down the middle, but a little wood glue fixed it perfectly. This balsa is very good quality and since it comes as a single flexible sheet it was perfect for maintaining the shape of the top deck. I used epoxy to glue it to the existing bottom layer, and then poly resin + glass to lay the top. I was pleased with the result. With some new sprayed on gel coat the deck will look new again.

Shipping on this site is outrageous. Bought and shipped exact quantity and item from another site and it arrived 2 days earlier for a fraction of the shopping cost which was quoted up front on the site.

Exactly what I needed for my '69 14' Pintail deck core

My circa '69 14' Pintail had water saturated end-grain balsa deck core. This was exactly what I needed to replace this and rejuvenate this classic sailboat.

Can't believe it cost $37.00 to ship balsawood. The lightest material on earth. I shipped a Bravo Gimble ring cross country for $15.00

Easy to use Balsa

I had a small soft spot in the deck around an inspection plate. I had access to remove the bad core and replace it with the new balsa. After epoxying the balsa in place I remounted the inspection plate.

Q: Is Balsa wood a good flotation material ?
8 years ago3 Answers
A: Then this is the material you need. It's kinda expensive but this site had the lowest price. Balsa is a good floating material. But the way it's used in a Balsa core hull it doesn't make a difference.

Q: I am considering building a drift boat .. I am familiar with end grain balsa construction (such as J24 hulls) and thought it or even similar material that does not retain water, would be a great choice for the floor / bottom of the boat ... any thoughts / recommendations?? best regards .. Stephen myles
11 years ago3 Answers
A: The end grain balsa will retain water if soaked. If you are using it as a floor, you must waterproof it with your fiberglas.

Q: Sir; I am replacing wet core in the cockpit of my Cape Dory 25d. I think the existing core is 3/8__quote__ and i have 3/8__quote__ replacement balsa core from Jamestown. My question is, do i need to use fiberglass cloth or mat to bond the new core to the bottom skin and if so, how can i match the existing cockpit level?

A: Thanks john, I am struggling with cutting the skin in the cockpit vs trying to dig out the wet balsa and inject epoxy? Area is about 8__quote__ by12__quote__

Q: I have a 1987 Carver Santego 2767 that I am restoring. The 1 cockpit deck lid is rotted and I need to replace it. Would the com-29306 3/4 inch provide the support I would need (after covering with fiberglass) to hold the weight of people?
12 years ago9 Answers
A: Hello Michael, I replaced the entire core of my 1976 Oday 27 using 3/8__quote__ ProBalsa. I then covered with 2 layers of 1208 biaxial at +/- 45 and 2 layers of 1808 biaxial at 0/90. Don't fall, a broken leg is guaranteed. The ProBalsa is easy to work with and provides a light and durable core material. Best part is it is one of the least expensive core materials. It accepts epoxy well which eliminates some of the more exotic bonding techniques such as vacuum bagging. Good luck with your project.

Q: i have a 20 ft pro-line open cc boat needs a new deck . what material do you suggest? money is important. thanks, bob hodges
12 years ago4 Answers
A: Bob, Not sure this will help with your problem. I did a repair on my balsa cored sail boat deck in a 2ft sq area. I cut the top fiberglass carefully, removed the old core, cleaned the area down to the interior fiberglass, wet the area with resin, layed in 3/8 __quote__ probalsa, wet the probalsa top with resin, layed in several layers of fiberglass, primed the glass, coated with gelcoat, sanded smooth and flush. painted with Kiwi Grip non skid. Came out strong and good looking. George
