I'm pretty sure the curve you get with the flexible metal is a catenary curve. I don't think it matters too much if its a perfect radius because... Snow isn't perfectly flat. Snow, as a mechanical component to the steering system allows for a bit of wiggle room I've found. Its funny, I've used all the radius marking methods you do in this video when I was making rudimentary skis for snowskates. If I was to make any now where I cared what the radius was I probably would jump into fusion, and use it like a calculator to measure what the length and depth of the side cut should be for the radius I want, and then just use the flexible metal ruler method off of that. I'm sure there's a way to do the same thing on a online graphing calculator. I've also been using just a 3" can of stain for marking the corner radiuses for all my various board builds for the last 14 year. Its more a dedicated radius tool than it is a can of stain at this point.
You’re a legend. This simplified a lot for me I hit a wall in my own construction. Put it on the back burner with school and other life stuff. Gonna get back at it asap hold the rocky.
I like your approach, I have used glass reinforced polyester battens from my sailboats sails. The tapered battens give nice parabolic curve, while the straight battens give nice circular curves. The can bend very far and will not deform.
The string method would work if you raised the anchored end a couple feet. Braided fishing line or 550 cord wouldn't have stretch making better curves.
I missed this getting posted, but it looks sick! A 20ft sidecut radius (~6.1m) is rather tight for a tree deck but not completely unreasonable, I've used 7 and 8m radii and they turn great in the tight stuff. I find with dedicated tree decks that they react much better when they're softer and/or they're mounted far back. I noticed that you were aiming for a 7mm core thickness, and that's about perfect if you're planning on using biax but I'd recommend getting closer to 5-5.5mm if using triax. Either way looking forward to seeing how it turns out.
I've got a surfskate adapter and I'm just waiting on some better weather to try it out. Once I feel like I get the jist of it I'll probably make a deck
First! So excited for this series. Looking at doing this for skis. Would you think it would be better to make two core blanks or a wider core blank that two can be cut out.
wow ok, very original and somewhat roundabout first attempt to get get a sidecut. would've thought the easiest way to do this would be just to design it on a pc, scale it , print it (likely in multiple pieces) and trace it onto the base. Funny thing I found out recently about sidecuts - this whole "its a part of a circle" thing is not exactly geometrically true. If your board is flat on its base when the circle is drawn (or designed on a pc) but slanted against the snow when it rides then obviously the turn will not result in a circle of the initially drawn radiius. This means that the sidecut radius is only somewhat of a comparison baseline then actually a "technology" you can rely on BUT this also means that someone who is working their way from a ground up design , wink wink, could potentially account for a slanted and tensioned board do design actual turn radius..

Damn, left us hanging! 🏂
Hey, did you ever finish this series? I’m interested to see the rest of the process and the finished board
Did you ever finish this board?
Starting to build mine today. Your videos are great inspiration. Good work!
05:30 that is some dedication we crafters needed. And the second method was really claver that just blew my mind!

What happens next?
Ah. The good old roll of tape. That's a decent multitool right there!

I love this series
Nicely done

Can you please make downhill deck bullet type? and how can i put some nice graphics on it
Could you do a surf skate deck video?

W video

If your board is flat on its base when the circle is drawn (or designed on a pc) but slanted against the snow when it rides then obviously the turn will not result in a circle of the initially drawn radiius.

BUT

He’s made designs on pc before, this series is about making it the easiest and low tech as possible
And then???
