Top looking finish on the board razzledazzle. Think you’re right about the blocks - teak. Light and strong enough and looks noice.

Think the next generation Unwireds with the carbon rods/nodes have foam rails, be a bitch doing the laminations of balsa that Bert is doing.Toby wrote:"as far as foam v balsa rails for stiffness ,,,,.
Yep Toby read most of Bert’s Sway threads and yes it is divinycell and it too is relatively expensive but it has good memory.Toby wrote:I should clarify the "foam" in the quote about foam rails isn't EPS, it's high density divinycell (sp?). In fact the board Bert's talking about in that thread doesn't use _any_ balsa, the divinycell is in place of the balsa. Sorta like the corecell that he uses now, e.g. on the deck of daryl's board.
I guess these high density foams are much easier to work with, but they don't necessarily have the same magic properties that wood can have.

Mad, what are you talking about? Have I missed something somewhere?
Think the skin is about 3mm Toby, rails are about 4x that (you can see the layers in Daryl’s pics). Remember they have to be bent to rocker AND outline. (where’s Munch he’s done this?)Toby wrote:The rails are about an order of magnitude thicker than the skin, so I doubt the skin affects the rail flex characteristics significantly.
Nah,nothing in Thai, woulda looked okay but wot'd it say, more bahts bert . Feels a tad skatey like my fishy, and going by tobes, that'll still be okay when it's bigger .Toby wrote:Not even anything in Thai?
Paddling out the back it paddles like a traditional board (not much planing or gliding). However, a couple of strokes into paddling for a wave and it just seems to up and go, building momentum and planing very easily. Riding along feels like you're planing on top of everything rather than cutting through as much. Mine's 21 7/8" wide but it's not noticeably slower rail to rail. In fact, it feels like because it planes so well it is easy to throw around when you have to (also the light weight and sharp rails would help this). It's easy to bounce off sections, again gliding over rather than bogging down.
Cons? the larger-than-normal surface and light weight make it get tossed around when duckdiving anything sizey. The larger-than-normal tail and light weight make it get tossed around when caught behind a section or on manoeuvers coming out of the foam. I can live with both of those.
Yeah, thanks . No, I can't answer , and didn't option balsa bottom, came that way lucky me . Being longitudinal to the rocker plan ( is that right ) maybe the balsa ties in with the flex, from rail-to-rail, like a twisting tree trunk??? scuse ignorance. It was a surprise to get wood .mad wrote:Daz, I gotta ask and I don't know if you can answer, but won't a ply layer across the bottom plan from rail to rail adversely afffect the boards flex characteristics?
My understanding is that the rails load up and release flex through the board, and the closed/eps foam structure allows for the transfer of energy/flex etc through it. So if you connect the rails via a sheet of ply, will this act as a sort of bracing (like a sheet of ply does in construction) and hinder the flex through the board?
I may be way off in making the comparisons so if anyone can elaborate, give us the drum.
Sweet looking stick by the way
Foot kept going too far up, so gonna let it .pinhead wrote:I've got a couple of boards with similar construction. All High Density (HD) foam ie core-cell top and bottom like Firewire is ok, all basla I found a bit stiff except for longer boards, but the balsa bottom with the HD foam deck is sweet. Flexy but with more pop and faster return than all core-cell. If you don't mind the woodgrain look I think it's the best option for shortboards.Surfa 69 wrote:
Just looked on the sunova website, its interesting to see they have a bolsa bottom as well, wonder how that alters the performance of the board?
