Operation Skenk

⟡ Winter Beckons – And So the Skenkboard Rises Once More ⟡

With the breath of winter already whispering across the valleys, and our humble town waking beneath its first silver frosts, the time has come again to prepare for the coming snows. Not for travel—not for survival—but for glory.

For the seasoned few among us, snowfall means only one thing: the forging of a new snowboard. Not the conventional planks used by the soft-booted wanderers of distant slopes… no. I speak of something lighter, shorter—kin to the ancient snowskate—yet tempered for the most savage and unpredictable mountainsides our land can muster.

The craft began long ago with a mere skateboard, its wheels and axle seized and stripped, sent down a hill in foolish bravery. It skittered like a drunken imp and refused to ride straight. But with two iron runners fixed beneath its wooden heart—ah! Control was born. A new pastime emerged from the frost: Skenkboarding.

And so, every few winters, when the grass sparkles under the dawn light like tiny frozen jewels, inspiration stirs again. I take to the workshop and shape a new board—adjusting the curves, refining the lines—ever seeking the perfect form for our treacherous, gravel-textured snow.

The last creation came close. Almost perfect. Yet I learned two truths upon the hills:

• The stance must be widened by roughly 40mm for true balance.

• And the board—gods bless it—was a tank. A sturdy beast, yes, but far from light. This season, weight must be shed. I can carve away a generous portion without angering the structural spirits.

And so the forge calls again.

Winter approaches.

The frost gathers.

It is time to craft the next Skenkboard.

And heres a video of a previous version from a few years ago.

But let it also be known: the coffers for these creations remain as barren as the winter hills themselves. Budget: nonexistent. And truly, that is where half the joy resides.

From hauling abandoned roadside pallets beneath the cover of dusk…
To liberating shower-panel offcuts from the depths of a skip…
To dissecting old railings with the enthusiasm of a blacksmith possessed…
This craft is less a hobby and more a trial of resilience and resourcefulness.

Fortunately, much of the scavenging is complete. I have already “sourced”:

• A fine sheet of 3mm shower-board plastic for the base—smooth, slick, and gloriously waterproof.
3mm plywood for the core, strong enough if treated with respect and occasional profanity.
Fibreglass woven mat and two-part resin, obtained covertly during a routine car service at a local garage (they shall never know their true contribution to winter sport).
• A strip of ribbed rubber matting for top-side grip—destined to keep my boots from abandoning me on steep descents.
• A handful of threaded metal inserts, salvaged from old furniture I recently dismantled and ceremonially set ablaze. These noble relics shall anchor both the bindings and the runners below.

As for the runners… well. They remain elusive. Not a single suitable metal scrap has presented itself. Thus I turn to the old magic: 3D printing.

If I cannot find runners, I shall forge them layer by layer, in multiple sections no longer than my printer’s pitiful 200mm bed. The entire length must reach a metre. It can be done—but I must first tame the beast, for the cursed machine has developed bulging corners, and demands calibration like a sulking familiar.

My first thought in a circle back to this previous post

And then I just had another thought

Nylon chopping board from £ pound land £

Lol ive not added any lubricants its very fast. But ive Been thinking about this for a few days. What can I use that is in a plastic strip form factor that is about 12mmx 12mm x 1m. I’ve looked at bump rails. Floor Beading. I may go with the conventional metal runner. This also adds needed redgitiy…

Found another videos

Today’s mission its to knock up a press. Last one I burnt thinking.” Im not gona need this again…”

so this is almost ready. By adding 21mm spacer between each layer i should have the 250mm required for the press

Recieved the sander last night so we can do the last of the shaping of the mold today.

Im currently printing a shit ton of 21mm spacers to go between each beam. Making this mold the required 10 inches wide… ill then cover the lattice with… something. Probablya sheet of the white plastic..

Im toying with the idea of using a vacuum storage bag, commonly used for clothes and pillow. to press the snowboard into the mold. I normally make a make and female sides. But im considering giving this a try… but im on the fence.

I just watched a video where a guy made carbon fiber airplane wings using the laundry bag vacuum method

Yeh aparently if u suck out the atmosphere.. theres a hella force.

(quick math)

We get the force from the pressure difference between outside air and the bag interior.

Typical snowboard area (example): 1.6 m × 0.25 m = 0.40 m² (160 cm × 25 cm = 4,000 cm²).

Atmospheric pressure ≈ 101,300 Pa (N/m²) ≈ 1.033 kgf/cm².

If you remove most air and leave 0.1 atm inside (a conservative, realistic shop-vac result ~0.9 atm differential):

Pressure differential ≈ 0.9 × 101,300 = 91,170 Pa.

Force = pressure × area = 91,170 × 0.40 ≈ 36,470 N.

In kilograms-force that’s ≈ 36,470 / 9.81 ≈ 3,720 kgf (about 3.7 tonnes of distributed force).

Ill order one.. and do a dry laminate test…

So im sitting here taking a poo… so you get a mid day update.. spend an hour or so rubbing charcoal on the bits im sanding then sanding it of untill it was square and level. And no charcoal remains…

now im super glueing a nogging ( the spacers I’ve printed ) to one side of a board. Im still waiting for the other load to print Then ill screws them to geather while trying my super bestest best to keep em in alignedin 3d space. And add a plywood topsheet.

Poo complete. Time to wipe….

Post poo edit.. Im.still waiting for the noggins to print. But I did find a can of expanding foam. So that will be going in the gaps.

Morning sexys. A new day and its time to get this bloody mold finished. I managed to screw em all togeather tidy with only a slight miss alignment that will be sanded out…

I did start adding the spray foam bit it was a bit shit.. didnt expand half as much as I thought. And I need another can…which ill get today or tomorow… however the last part of the hardware came today… woop woop. We be pressing soon.

Edit. When back up 10 mins later and its expanded… Lol one can may of did it . if i was more conservative lol nvm..

And the vacuum bags have arrived… i do love me some good shinanigins. Ill see if the mold fits in it later. I’ll also suck a pillow to check how long things take. As I only have a short time window with the epoxy.

It will fit! I may print an attachment to go on my hoover. For increased suction advantageousness…

So the im out side in the dark and cold with a head torch trying to to the final shaping of the press… im cold…

Anyway I’ve done a ruff shape on the bottom sheet. And chose my layer order. No pritty design this time I can’t be assed to waste 3 days and another soldering iron… it turned out just under 10mm. So when we add the 2 layers of fiberglass and resin we should hit 10.5 to 11mm total thickness.

So hopefully by end of day ill have a finished mold and I can do a dry run ( no glue) and ill uploads a ‘sucky sucky’ video… coz thats the bit we all wanna see… lol… will it bend..?

In simular news.. i saw a video on pre bending wood for lamination using heat by Melting the lignin in the wood . Using a metal pipe with a blowtorch.. I can’t be assed to build a steam box and then wait ages for the ply to dry back out. I may just try to use a old clothes iron…

Anyway im got a little but more sanding to do on the mold. And then we are off to the races…

Oh and I have to print the go between for the vacuum bag and the hoover.

this is currently being printed

It all worked to be expected.. the bag pulled in between the mold and the board layers .. which i had to wrestle out… took way to long and was way 2 awkward… so it looks like im gona have to make the female half… of the mold ffs… this involves me scouting and retrieving more wood… and another week of tinkering…

Found 2 mini pallets. Bit shit as ill have to stack em to make the profile.. and use the thick bits as beams…

And thats where im at… ill finish this profile tomoz and ill make the 2nd one and assemble it tomorrow…

Midday squash and biscuits break…

Lemme take a min to say how much I love and adore cutting wet soft wood with a rusty blunt pannel saw… (sarcasm)

So both profiles are cut and are a close enuff match to eachother i just need to cut in the curve.. then add the beams which also need cutting. (Bigger wetter peices) yay fun

Molds all done. Just gota make a smusher mechanism. I need to find better ply laminates. This stuff is shit..

Edit. Turns out that I’m bending it the wrong way… I did a dry sheet test on a strip using a heat gun… and that bent with no issue. I also pre bent the plastic bottom sheet so it fits in the mold.. ill try get ti the hardware stor for a bigger piece of ply that I can cut with the grain going the correct way..

So another day of dragging this out…

Today im gona pop to the hard ware store to get some plywood with the grain going the correct way… I dont have clamps to smush the male and female Molds togeather yet. But as I have pre bent the layers. It should mitigate the issue we had with the vacume bags… ill keep you posted… wish me luck.

found ply with grain going the right way.. now to take it home and cut it and bend it

As you can see I had no issue with the bag pulling under the mold this time. Due to pre bending the layers using heat… ill do the prep shortly and ill gue it up today… hopefully

So now I’ve prepped the layers. Covered the mold in plastic. Im currently printing some little back stops to keep the layers aligned as it pressed… and we are go for pressing… hopefully one of my buddy’s will come help.

Layers all prepped. Just trying to musta up the bollacks to start. And mix the epoxy

Its done… it was a bloody nightmare. Bag leaked… shit was moving.. tried a bag in a bag but still leaking. I also tried wrapping it in tape… im now sitting here occasionally pumping air out of the bag untill it all sets… this is gona be a fun 12 hours

Ahaa I found the hole. Taped that bitch up and I think we are holding a vacuume….

Is it me, or you just had a moment of turbomolecular temptation?

Or, a regular vacuum pump is probably enough, but an electric one would be a significant upgrade, I think.

:thinking:

I took out the majority of the air with my cleaner.. but she’s screaming when I do it. So I did the last bit by hand.. literally 3 or 4 pumps. And its almost un pullable. I sealed the leak now and she’s holding a vacume. I do occasionally go give it a light pump… ill pull it out after work tomorow evening… fingers crossed
