if you've got enough force, do the whole thing at once. but doing one 9or two laminates at a time is probably better.

I recommend putting the fibreglass between the layers, it doesn't crack that way. It depends what kind of glass you have as to which direction you want to lay it too if you have Bi directional glass, i would run it so it is diagonally across the board, this redces twist, whils still giving a bit of flex in the parallel direction. if you want it stiff as a dick, use carbon running parallel with the direction of the board, I would put it near the bottom so it works primarily in tension.

Your direction of veneer should run perpendicular on successive layers.

0.8mm ply, people have talked about glue in other blogs I don't know too much about this.

Epoxy for the fibreglass (or vinylester if you want mega flex)

Read the thread. Every discussion it's all there.
We get annoyed at the same questions we've answered before.

Rant over. I did ask all these questions once. And Steve's answers to those questions are still there on like page 17 or 7 I dunno.
In a nutshell
Use what ply you can get. If its free even better. Hoop ply has been used heaps but some hardwood bracing plies are good.
If they are under 4mm press all at once. I've done 3x4mm one go all sweet. But I use veneer now. No I won't tell where I get it cause they asked me not to and said they will only cut thicker veneer for me;^) reminds me I gotta ring them.
Glue, if it sticks use it.
Titebond if you can get it.
Fibreglass, use it, epoxy, good luck. Play around.
Ply, don't soak it cause the glue in the y usually is crap and you have no way of telling weather it's waterproof and It just doesnt need it.
Seriously everthing I just said then has been said 20 times before.
PRETTY SURE THERE IS A DISCUSSION ABOUT BEGINNER TIPS EVEN.
I better slow down on the coffee hey Steve.

Lighten up dude you summed it up when you said you haven't had time to read it yet. Well I took the time to reply. And I gave heaps of help. Man up and take a bit of stick. I didn't have to help you. But I did. remember your about the 59th person to ask the same thing..
Half of what I said was exactly what you asked for. I think you did alright. Most people would of just said "read".

Hola Dean - we can be a fiesty bunch...  The Board Builder forum has ship-loads of questions and answers - it's well worth spending a hour or so wading through them - yes, there's plenty of shite in here too, but you'll soon find out who has the ducks guts of advise...  look at Fat Pidgen for the top end of hand made boards - Steve's moved onto foam-core awesomeness so somewhat out of the league of a beginner (unless you've got a really rich dad/uncle).

Real thin plys/veneers (0.8mm) means you need lots of them - no issue, but you'll spend a lot of time putting glue on each sheet.  what sort of press have you made up?  if it's something like a rib or rail press then 2 x 6mm or 3 x 4mm work very nicely for a sweet concave - if you can get marine-grade ply, all the better 'cause the glue used laminating the plys is waterproof and the facings are generally clear of defects.

Glues range from the "bucket-o-cheapness" that you might pick up at the local Bunnings - it works, but the bond isn't as good as you can get - as with most things, the more you spend the better the quality, but you don't need to go mad.  The Titebond I, II or III is some of the best wood glue you can get your hands on and isn't that much more expensive.

Look at some of the press photos of the members of this quirky group and you'll get plenty of inspiration - good luck and read/browse a bit first then your questions become a little more relevant and less likely to attract a noob-rating - we all start as noobs after all...

Welcome Dean! look forward to seeing your build.

Your board if built with luan ply will snap ( if it was really cheap ply it most likely is luan ). You may be able to save it by fibreglassing it well. Fibreglass is structurally the strongest on the top and bottom as your outer most layers. It can be put in between layers but it won't do as much. Do not put it in the exact middle of your layup. It will do nothing but add weight there. Good luck..

@ Adam. Whoa Adam ease up dude! I did answer your questions not all that long ago but I didn't carry on like a pork chop if you recall. Dean wasn't asking you personally to answer his questions. If it was too much trouble why did you even respond?

Joys of the Internet.
I was just havin a joke I probably went to far left field. I gave help and made some stupid jokes. My bad. I put more energy into the jokes than the answers. My problem is that I'm just not very funny....
Sorry dean.
I was being a goose. Or as steve said a pork chop. I really didn't mean to offend you but now I read it again I can see how I seemed all high and mighty. Or pork choppy.

thats ok adam im sorry aswell, i had a the worst day at work, n i snapped pretty easy, sorry man!

 thanks everyone once again, the board is in the press as we speak!
 it looks like its working so fair, only problem is that the partical board (on the base) seems to be snapping, i might have to put a support beam that runs the entire lenght next time, just to hold it together!,
ill trry to put up sum photos later on!

good to hear Dean - yeah Chipboard is probably not the best as the base-board on a rail press - unless it's uber-thick (25mm or more) - I had a similar issue with some prototypes before going for laminated pine - even at only 20mm thick it doesn't hint at being a problem - tightening the project down evenly is also a tip - don't go to hard at one section before moving long to the next set of nuts...  Post the results!
