Heaven help me! I'm going to do another e.wood compsand. I built this e.balsa compsand a few years ago. I like the way the e.balsa rides, but the look is a little 'pergo flooring' like.

I thought that I would leave the grain showing and dye it translucent red. I was following a thread about dying e.balsa that used Rit dye rather than the more expensive wood dyes.

The process uses Rit dye and Isopropyl Alcohol. The theory is that the Alky evaporates quickly leaving the dyed wood behind.

The mixture:

Using a cheap sponge (and don't forget the gloves!) I spread the dye and alky solution on a section of the raw e.wood. The alky evaporates very quickly leaving dried and dyed e.balsa.

@ TXSurf - I like the look of the e.wood too, but I'd like to get a little different look...not sure I like the dyed look though.

The board I built a few years ago, before external lamination.

Thanks. I'm loving the look of the e.wood pinlines on this board. The rails are built up using e.balsa and e.cedar (I think). The darker color, looks cool to me.

How much does it weigh?

I love the look of wood, but that other thread with the beautiful all wood boards had their small fish surfboard come in at I think was 11 or 13lbs. Granted small was just under 6ft.

The dark wood contrast looks great.
Old    surfdad            12-04-2009, 5:57 AM Reply   
Yeah the HWS weigh a ton, the board above isn't mine (note the shaping bay that is INDOORS! :-) ) but I think it weighs a ton also, it's a solid balsa board that was CNC'ed to shape...mix of old and new school.

I also like the deck inlay of the checkerboard veneer they did on the deck.

My e.balsa compansand only weighed about 4 pounds, ready to ride. I think that was 3mm e.balsa skins.

I also really like Josh "Speedneedle" Dowling's rail treatment. e.Paulownia and D-cell layers. There's some practical advantage to these also. The super lightweight e.wood tends to soak water like a sponge, and of course a low density EPS core will give a nice home to water. The D-cell is closed cell and water-proof'ish. Tasteful paint pinline between skin and rails.

This e.balsa compsand will be a perimeter stringered board. The rails will be e.wood and built up to about 1/2" or so. The skins will be 2.5 mm e.balsa top and bottom. With the e.wood rails there are a few differet ways to attach the skins. 1) The skins don't wrap the rails. 2) The bottom doesn't wrap the rails but the top does and 3) Both the top and bottom skins wrap the rails. The theory is that wrapping the rails stiffens the top or bottom skin somewhat. I my first attempt, I didn't wrap bottom and didn't notice any benefit.

For this build, I want to have some different color wood or stripes so I will only wrap the first two layers of the e.balsa build up.

I'm starting the rail buildup with some leftover divinycell. The d-cell will protect the core in case I get a ding on the rails. The e.balsa will suck water like a sponge, but the d-cell will prevent ot from migrating into the eps core.

I use my hotwire rocker template to rough out the shape on the d-cell, leaving it as a 2" band which will cover the full thickness and give me some to shape away.

I do the same thing with two sheets of e.balsa per side, forming a patchwork as I'm using 4' lengths. I overlap the seams but place the seams closer to the nose where it's not overly important.

It's hard to see, but along the rails 3mm dcell and then 2 layers of e.balsa.

I'm going to add diagonal pieces on tha tail. In ocean compsand's the theory is that the diagnoal's create more flex in the area covered by the diagonal. I've done them before and behind the boat, I couldn't tell any difference, so I'm using them strictly for cosmetics in an effort to avoid the look of pergo florring.

I start by laying out a sheet of paper that I trace the tail on. When I am creating the diagonal pieces, the outline of the paper gives me a visual so that I can cut the end of the diagonal out by the rail.

With the diagonals done, I'll cut the lengthwise pieces so that butt up against the diagonals. The only tricky part is I wanted a "plank" down the center, so I had to notch the "V" where the end of the diagonals meet.

Good to see you to working with wood again Jeff! Working with it is the first step to overcoming your aversion to it!

Just think, some day you may be able to hug a tree

LOL! There is NO TREE HUGGING in my future. :-) It's not that I have an aversion to working with e.wood, I just HATE the stuff. :-)

The deep ricj tones of the e.wood after lamination, can't be beat, but getting the stuff to that point makes me crazy!

I'd like to try a chambered / hollow e.balsa that is cnc'ed. I think that look "might" be worth the trouble.

The planks don't need to be exact, but very very close is good :-) I'll vacuum bag them down and with a 2 oz eglass underneath, there is a little bit of swelling and "compaction" that tends to manage minor imperfections.

Right side, both sides and rough mockup of all the pieces.

The core of the compsand is 1# eps. It's super light and basically just separates the skins. However, that also means the fin boxes are sunk in anything solid. With a HD foam skin, it's easy enough to notch the top skin which prevents the fin box from flexing under load.

Another option is a hd foam insert, but I have found that creates a fulcrum between the HD and LD foam and fractures/delams start at the transition from the HD to LD foam. So for this build, I'm going to sink some e.balsa into the eps before shaping the bottom.

The e.balsa box supports cut to size, sunk into the box and the bottom single concave shaped.

I align all of the skin pieces and then tape them together. The tape doesn't do anything other than hold them together until I can lay it flat on the shaped board. I flip the front of the tap over creating a "tab". The tab won't get stuck down by the vaccuum and makes it easier to remove the tape after I pull the board out of the bag. Otherwise, I'd spend hours with a razor blade trying to pull up an edge.

Thanks Duffy!

After I have all the pieces taped up, I carry it out to the shop and lay it in the roker bed, then place the shaped eps core on top, align it and mark the outline pretty close to the final shape. I'll trim it later with 36 grit on a block.

This is the "inside" side of the bottom skin.

I laminate the skins to the core using 2 oz eglass. It's exceptionally light, the bottom fabric weighs less than 2 oz in total. A proper resin to fabric ratio would be 1:1, but it's really hard for a garage builder to measure out 1.5 oz of epoxy - well at least it is for me! :-) I mixed up 5 oz of epoxy, and wound up with almost 2 oz waste. I also used about 1 oz of epoxy and with a small paint brush, painted some epoxy all along the outside inch or some of the skin, so that it would stick well to the rail build up and core.

The 1.5 oz of epoxy was then pushed into the e-glass and I laid that down on the core, then carefully picked up the skin and laid that down on the core/laminate combination, tape side out :-)

@ Show, so not!!!! Or if I am by default, it's a reluctant one! :-)

I forgot to mention, in the picture above, that I tape the skin ONTO the core in 4 places, just to prevent a disaster, as I move the core/skin into the bag.

Trimmed flush. You can see a little bit of resin bleed through - that distressed me no end on my first build, but it disappears with the exterior lamination. The entire surface will absorb the resin and the bleed through blends right in.

To trim the slight overhang on the skin flush to the rails, I start with a single edge razor and run it such that the "handle" is flush with the rails, which leaves about 1/32" left over and then I use a sanding block to bring the rest down flush.

The next step will be shaping the deck to the final foil. Then I will finish building out the rails.
Old    surfdad            12-12-2009, 7:28 PM Reply   
Deck shaped. This build technique does pose one challenge. I still have rail material to add, so as I am shaping the deck, I am visualizing the finished rail. If I had a rail guage (the rail shape template) I could have used that to continually measure my progress.

Ready for the deck skin:

I wanted to do something on the deck to break up the "pergo"'ness of the balsa planks, but so much of the deck is covered with traction, it was a challenge for my e.wood averse (adverse? :-) ) brain. So I decided on doing a diagonal pattern on the nose similar to the tail on the bottom.

Rather than 4" wide planks, I decided on 2" wide planks...visually, the 4" diagonal at the nose seemed to overpower the concept. The first thing I did was take a spare 4" wide plank and split it into 2 - 2" wide planks.

I'm going to tape and trim the deck tonight. The deck on this board is "mostly" flat, but there is some dome to it especially out at the rails. The e.woodworking guys have a bead and cove bit set that will allow the "boards" to "curve" along a flat surface. In my situation, the planks will curve to conform to the surface, but I knock the inside bottom of each blank to allow the planks to more easily butt against each other without a gap on the surface.

I swiped this picture from some demented website for those e.woodworkers:

I'll attach the deck to the ore using 2 oz eglass. I also add a patch under the deck where the feet are. The external lamination will then be a single 4 oz top and bottom. To help the e.balsa conform to the the start of the radius of the rails, I'll thin the last 2 inches along the area that meets the rails using 60 grit.

In a semi-tribute to a bygone era of e.redwood boards, I opted to build up the rails with a single layer of e.redwood, the remaining layers will be e.balsa. My source was the garden department of Home Depot. :-) 3/16" e.redwood bender board.

I'm going to bag these separately as the e.wood is a bit stiff.

The blank with the deck skin trimmed flush.

I am bagging the e.redwood as it didn't stick well with super glue. I think that I will bag the first e.balsa rail material to the e.redwood, after that when it is e.balsa to e.balsa I will use the CA glue.

I'm going to add a tailblock to finish up the tail. I start by drawing a heavy line where the final shape of the tail will be. The tail block will be composed of alternating layers of e.redwood and e.balsa and running on a diagonal. If you look closely in the picture you'll see the pencil line where I'll cut the board to glue on the tail block.

I cut 6 pieces each of 1" x 7.5" e.redwood and e.balsa, slathered each with epoxy and stacked them in a alternating pattern. Each piece had a mill finished end and I stacked the pieces so that the milled ends are together. After glued and stacked, I wrapped some masking tape on each end to allow handling.

Out of the bag this morning and a rough visual of what the tail will look like. The two sections will meet in the middle with @ 45 degree angle and will be shaped to the rounded squash like dark line.

You can also get a good idea of the visuals that can be achieved with various e.woods or even e.wood and cork/HD foam.

I'm gluing up the two pieces of the tailblock first. Then I'll align that on the tail of the board to to mark the cut through the board, hopefully that will net me a perfect match.

Inasmuch as, I am now a master e.woodworker, I decided to swap the layers of the e.wood on the tail block - because that's all you can do with the stupid stuff! :-)

I'll sand and match the various surfaces and then 5 min epoxy the tail block to the board. Once that is all attached, I'll start the planing, cutting and sanding for ages.

Thanks for the props Steven and for following along. The e. is for EVIL. :-) The Readers Digest version: My first attempt at building an e.balsa compsand (the very first picture way up in the thread) was riddled with problems. The foam I ordered got lost in Oakland and never made it. The warehouse of the retailer where I originally ordered my sheets of e.balsa BURNED DOWN after I placed my order, but before shipment. Everything that COULD got wrong did! :-) The running joke from all the e.woodworkers is that wood is GOOD. And boy did they go out of their way to make sure I heard about it. I, being a more rational person than those folks, know the truth. That truth is wood is EVIL. Hence, e.balsa, e.redwood and all things e.wood. :-)

Next is the nose block. Mostly it will just fill the gap where the rails meet at the nose, but the piece of e.redwood will add some resistance to crushing/denting the nose.

I'll shape a small "plug" and then route a matching hole in the nose. I am using the soft e.balsa on the outside of the block as it's much easier to shape than the e.redwood.

I am gluing this up with titebond e.wood glue.
