jojo, been sitting on these 1/16" bamboo plys since a while now (from roarrockit) and always wanted to build my own board … but then the loaded vanguard happened to me and I really fell in love with that board, hard to imagine a better carver right now. but there are a few very minor things Id like to change - first of all I want Id like the board just a liiiittle bit wider, probably 1cm is already enough. 2nd Id like the middle section to be just a tiny bit stronger and the rest of the board a little flexier - I Imagine that way I could pump harder and have an even springier energy return while at the same time its damping cracks and bumps even better with the softer nose & tail sections.
In any way, Ive never built a board yet all by myself, but since I got a vacuum setup, the bamboo plys and enough experience with fiberglass and cfk I just went for it.
I started with measuring the thickness of the flex 2 vanguard, since nothing will affect the flex as much as the thickness and the strength of the outer layers. its about 1.1cm with my added fiberglass top layer - with the 1/16" bamboo veneers, I decided to start with 4 layers for now, sandwiched with fibreglass which is apparently a good lively springy combo, so:
bamboo fiber bamboo fiber bamboo fiber bamboo = 7-8mm thickness right now
I worked in the things I wanted to pimp a little in the correct layers, so before the streetside bamboo ply, I added 3 wide unidirectional stripes right in the middle of the board along the boards axis - middle 30cm, outer sides 20cm for some sort of smooth stiffness transition. below the upper bamboo layer, I added 2 unidirectional 45° crosses for torsional stiffness, because I need to get edge pressure to the trucks. now, keep in mind: I actually have no clue about building boards, but thats what my naive mind came up with and Ill just try it now.
the outer layers are all bamboo right now, because Ill sink in enclosures and wires as usual (or well, sinking in enclosures by about 1mm only so there wont be a transition board->enclosure like on my jet spud build). so either way Ill cover the bamboo up later with either fiberglass if the flex suits me, OR carbon if the flex wasnt enough! if the flex is completely far off, ill add one more bamboo lower top or bottom - undecided yet!
my active vanguard - went for the annual maintenance and want to change a few minor things like sinking in the lids of enclosures for some splash proofness. you can see the torsional stiffness crosses (its otherway round in the picture - the crosses will be on the boards top side and thats how it cures right now.
finally, since the bamboo/fibre composite works against the cambered board and I wanted to preserve the vanguards camber profile, I added some weights for curing. nothing feels as great as well balanced lively camber.
curing as we speak, Ill keep you updated on this experiment
