Bodysurf handplanes by injection

16/07/2018 at 23:58

Hi everyone !

As I started to have some showable things, I wanted to share them with you.

I collect plastic around me in my familly and friends that are not yet converted to 0 waste movement :-), and when I can on the beaches after a surf session.

I concentrated myself on a way to make a handplane for bodysurf, as it is my favorite time in the water. For the moment, once the plastic sorted, cleaned and shredded, I mould it into a plate with a oven and a very basic mould. Then I bend the plate after putting it back to the oven (100 to 120°c depending of the plastics), then I finish the shape.

As I still get some lost (the dust from sanding), I also started to built a injection machine, but it is still on going 🙂

Hello. This is a good example of a recycled product. Thanks for sharing with us.
[EDIT] What is the thickness of the plate you make?

The plate are 6mm thick, here a picture of the mould (with a new moulding under preparation 🙂 ). On each corner, I placed a 6mm thick piece of metal to keep a regular plate

Here is my first batch, to be tested with friends this week-end 🙂

@lagrenouille, very nice! Would be great to see them on the bazar!! 👐

Sweet 🙂

@katharinaelleke @mattia-io thank you for your comment, it push me to continue !!
I think I might put them on the bazar one day, but not before I duly tested them : as if they break it will be in the ocean, it shall not happend 🙂

Super cool!!! Did you manage to test them?
I wonder whether this style of plain would be possible to make? https://ottersurfboards.co.uk/products/handplanes/

No straps needed!!

Wicked work dude 🙂

Hi @ellieewart !

Yes I surfed them exclusivly since one month, and I gave the other to friends and to a surfschool. I got quiet good feedbacks, as they are thin, they are very easy to swim with.

On these handplanes specifically I don’t think this system and handle would work as they are too small. But on longer ones, i should be feasible.

Super cool!!! would be wicked to try one out sometime dude

I improved a bit the system : now working with the injection machine !

It is a very simple mould :
– Top : stainless bended plate (in width direction) with standard injection nozzle
– Middle : 5mm plywood cut to the desired shape
– Bottom : same stainless plate than for top
– Lots of bolts to keep it tight
– Size increased injection pipe : I went for a 1’1/4 pipe with internal diameter of 35mm. I did that to be able to melt 230-240g of plastic (final product is 190g). Standard 1′ pipe wouldn’t have been enough

Big improvement is for the stiffness of the product. The first ones with bended plates tend to regain their initial form if heated again (for example if left inside a car under the sun…)
Second one if for waste created, I am very close to the final form and only have to shape the rails, which is done with a knife above a box to reuse shaving.

There are available in one local surfshop, and soon on the bazar 😉

I recently find my definitive shape, then cut the central par of the mould out of stainless steel. It works far better than with plywood, and nothing get stuck on it.

I am currently preparing a detailed documentation, but you can find under some picture to understand how the mould is built :

Mooi man! Cool to see how you can get such an organic form with a relatively ‘simple’ mould 🙂
