I've started making these out of two sheets of 4mm ply so that I can put the nose lift and concave into them when I glue them up. The concave keeps the back 3rd of the board stiff so I can make the board a bit thinner, which lets the nose flex more to aid in wave catching and turning. The wider one has obvious parabolic rails, but the middle board, despite looking more like a traditional bellyboard, also has subtle parabolic rails. A bit hi-tech for bellyboards, I know, but I just love riding and building these things!

Super boards! What grade ply do you use (marine, WBP?), what adhesive do you employ?

I'm not sure of the grade, but it's $8 a sheet, and I use polyurethane glue.

I've just built a similar board from WBP (water and boil proof) ply with epoxy as the adhesive. I've used the epoxy to join the two pieces of 4mm and to seal all the edges of the ply wood as WBP is not salt water proof unless treated. Have you had any delamination problems to date?

I've never had a delam, even with the really thin flexy boards. The last couple I made I used two layers of 3mm to see how the flex would affect the ride. They work great in small waves!

This is the sort of reassurance I like. I've built the rest of my boards out of marine ply because it's very trustworthy but have gone for a lesser grade this time because of cash flow problems (i.e I'm broke!) I've sealed her well and am going to finish her in yacht paint so all should be well.

My reaction is that there has been little documented progress in the genre and many are dredging up things that have little/poor performance. The ply ones I saw many of in the early 60's yet the nostalgia buffs continue to think them as the duck's guts.

FFS read Barry Hutchin's interview for some direction as to how it might be

I was there at the forefront, not dicking around in some new century retrowank.

Get real eh?

Ha Ha!!!!!! Thats got to be a parody yeah???? If it is, then its hilarious!

OooooH!!! There at the forefront!!!! Ya big pioneer you!

If that's a serious comment then I think you might have the wrong forum! Go back to Swaylocks!

Surfing, and especially bellyboarding, just isn't that serious. I grew up in a country where NOT getting shot meant you were having a good day! That's slightly serious! Get over yourself mate!

"Get real".....about plywood..Ha Ha..that's excellent!!!!

when I made my first belly board 50 years ago ,( and I call them belly boards because I did not know what a paipo was) they were made of plywood because that was all we had. my dad got us a sheet of 1/2 " ply and let us have at it. now I have made them out of ever type of wood ,foam, epoxy and so on. but the most fun I ever had is on a old ply belly board. they may not be the fastest or turn the best but all it is about is fun. because if yous aint having fun you need to go home and watch tv on the couch!

There is one outstanding characteristic of the MyPaipoBoards Forums over the years. Mutual respect and acceptance. Many of us build and/or ride different types of prone vehicles -- there is no competition between woodies, foamies, plasticized, shorties, longies, etc.

We do welcome positive, constructive criticism or critiques of different board forms. It is also important to implicitly recognize that each and every board design is an optimized solution and a set of design compromises.

I for one continue to marvel at the ability of so many different types of boards being successfully ridden in so many different surf conditions. Nonetheless, it will be hard to tear me away from my modernized 1960s fiberglass/foam paipo/bellyboard. For the sake of some fun I am thinking about having a bonzer-style paipo built made of EPS/epoxy. Am trying to get smart on the design features to incorporate and have a little dialog going on with the owner of a bonzer paipo in central California.

Lastly, as my grandma used to say, "If you don't have anything nice to say then don't say anything at all!"
