First anything ever shaped, it was fun and I’m not sure how to finish the details…or if I should change the design so that it could actually be ridden…any criticism is constructive
Are you doing a paipo/belly board type of situation? Even those need some rocker in the nose.
You’re going to have to glass it at some point, too.
My advice is to go back to the drawing board - literally. Use a piece of butcher paper or tape several pages of paper together and draw out a full-sized half-template, complete with the curve you’re looking for. Cut it out and tape it down over a piece of your core material and then use a saw to cut ~1/4" outside of that. That way if your blade wobbles or doesn’t cut completely vertical you’re not screwed. Come back and true up your template with a sanding block (piece of 40grit wrapped around a small rectagular section of that particle board).
Watch some youtube videos on how they cut rail bands and use your sanding block or a planer to do the same. Take your time and do it the hard way if you have to - long strokes down the length, not short strokes across the rail.
The home improvement stores sell shapable foam for cheap (like $10 or $15 for a 4x8 panel) ; you’ll just have to add more glass to your glassing to compensate. The sanding block described above will cut through that stuff like butter. If you’re trying to do a 2-thickness core it might be easier to cut and refine the top layer to your desired shape and glue it to the bottom layer. Maybe leave 1/2" around the outer perimeter dry so that when you’re shaping the rails you won’t have to contend with any glue lines on the seams.
Take your time and enjoy the process. You can definitely do this.
yea paipo belly want to use it in hollow waves. planing hull (not sure if its a functional design on mine or not) might need some criticism. ill add some rocker, how far down? why do i need foam? not sure what you implied or described there
Foam is easier to work with and it will actually float. You can do the shape in wood or particle board but for the most part you’d still need to glass the outside to keep the water away from the wood (same is true for most foam, too).
If you’ll look at body boards you’ll see they’re not completely flat. Even those have a little rocker in the nose, not to mention the additional rocker that the users add when they bend them whilst riding them. A dead flat bottom is okay for a skim board but those are made for skimming, not surfing.
Is that OSB? Doesn’t that absorb tons of resin?
Fantastic work Pat ! Go out and ride that board and youll learn a lot.
Everyone here started the same way so welcome to the family / clan / cult of foam and fibreglass !
Dont forget to post a ride report on how it goes.
Whats your plan for the next one.
is that MDF or ply?
never seen a water craft made from particle board
Since its so heavy you should really try and profile or thin it out like a paipo but particle board MDF composite has no shear strength its just hardened wood pulp and glue
you might want to glass it as a precaution but seal it first with something to combat the end grain.
you can build some unreal paipo spoons with marine ply.
We usd to build those in shop class and ride them in the late 60’s early 70’s.
great memories…
cowabunga!
Nice thinking outside the box, but OSB swells & weakens when wet…Also during manufacture, they apply a wax like substance to the surfaces during the molding & compressing process. Doubtful that you’ll get any resin or fiberglass to adhere to it . I think you better start over with solid wood. Good practice though!
So the mechanics of the planing hull seem possibly functional? Posting more pics soon with rocker adjustements. I do wood framing so I have a lot of extra scrap 2xwhatevers. Also a lot of good 1/4 osb that I want to shape into like ten or fifteen different paipos and alaias in time for the Newport board fair
Looks like you tried to shape it with a skil saw? If you are trying to bevel the wood, just set the degree on the saw at about 30 degrees. Just watch your fingers.
yeah ride it,if it desinegrates
bitchin,make the next one outa somthing else
nail it to the wall like a diploma.
inspiration is where you find it
be inspired reinvent the wheel
they were really shocked when the guy made a round one
let alone the guy that put an axle in one
then there was the guy that put
the axle in the equidistant middle!
what do you do … put in the middle first
then shape the perimeter?
or shape the circle first then put in the axle hole?
do one of each,or just do what the big THEY say.
go man, dont listen to some old disc jockey
just pick up the trumpet and blow.
…ambrose…
ambrose good to read ya !
Turn it into a skateboard! Love seeing people dive right in and get dirty.
