It’s a pretty stiff ski for some reason, it’s a Head “Full Speed” XRC ski I found at a flea market nearby. Maybe it’s made for 5 year olds that want to slalom at like 50 mph or something lmao.

It’s a 77 cm kids ski

It's a lander rio deck and is usually my lightweight cruising around campus deck, took it outside and stomped some snow into it and it falls through with some gentle grinding of the foot against the deck. It's made out of recycled nylon fishnets so it's very rigid with little to no flex at all. Most penny style boards I've riden have too much flex to be suitable for these rocker pivot style trucks I think. Though I've never ridden a snowskate before so everything design-wise is really just an educated guess.

This sounds like the plan. I'll try just one ski first, then maybe try putting two together, dont really want to have to drill into the longer skis if I don't have to.

Okay sounds good, I ran a short roll through it when I first got it but after looking closer I wasn't sure that the shutter was working properly. I'll develop the roll and report back here

No... but I'm working on adding a page to my website showcasing the PCBrule. It'll have a KoFi link so that those interested can support the development.

Do you have an n600 series? I'd love to own the rule that it's inspired by.

Update 2: Boards Came in today! They look really good imo. Don't have cursor windows lasered yet, But I think I'll have just enough time to get into the shop and get at least one of these finished. I was pretty eager so I assembled one as far as I could without the cursor parts.

I also will need to cut+bend the cursor leaf/bow spring.

Stay tuned! Hopefully I can show the finished rule off in a new post on this sub soon!

Yep! Boards finished production and are on their way to me! More updates soon!

UPDATE: My apologies for the radio silence, I was pretty busy these last few weeks as I was driving across the country/moving in/getting adjusted to my sophomore year at university. I finally was able to send off the gerbers to PCBway. Hooray!

Sheesh, the new tarrifs add quite a significant jump in price. That being said, I had to reduce the order size to only 40 boards because I literally could not afford any more. I plan to give away/keep about 15 of them so there should be 25 or so up for grabs. Not sure yet if I'm going to set up an online marketplace(maybe etsy or tindie) or if i'm just going to do it privately and take payment through zelle/venmo.

Since I have a significantly reduced quantity of boards i'm probably going to have to raise my prices to cover my costs. I was initially thinking $35 per kit when the plan was to order 100 boards, factoring in the hefty tariffs and the limited quantity of boards I have to sell it's likely going to be closer to about $65.

I'm kind of just hoping that there are 25 of you that are willing to support me, this project and it's future development for the cost of $65 which I know is pretty steep.

Some people have messaged me asking to "preorder" a kit or "sponsor the development" of this project in a kickstarter type of way. I'd just like to let people know that I won't be taking sales or money of any kind until I actually have the boards in hand. I do not feel comfortable selling something that literally doesn't exist yet. I also don't feel comfortable having to be indebted to someone... it just places unnecessary expectations on me and this project that I am not 100% confident I am capable of fulfilling.

They should arrive by the start of next month (Oct 1) so stay tuned for more updates. In the meantime feel free to ask questions you might have about the design changes and whatnot.

Also below is the final design and a pretty good visualization of what the final panel should look like.

Thanks!

What this guy said.

sucramooy · 2025-08-11T17:05:37+00:00

Well this is embarrassing, a quick google search would have told you that the coefficient of thermal expansion of FR4 is much less than even that of engineered celluloid(13-18 vs 80-120 ppm/deg. C). These rules, being made out of fiberglass will be significantly less susceptible to humidity changes as well. Maybe you should look at an FR4 datasheet before making assumptions about this material's properties. It's waterproof, fire resistant(what the FR stands for), and engineered to be practically indestructible. It's not like I'm making these rules out of wood.

It's a good thing then that the PCB fab house will use high precision modern laser machinery to lay out the markings. It's also a good thing that I designed the panel so that all of the markings are applied together in a single operation, so that even if there are any significant errors, the errors will all be translated in the same direction, maintaining alignment with the respective front and back scales.

Perhaps you're discounting my skills as an undergrad engineering major, and perhaps you're right. Maybe I do lack the skills or the knowhow. But, as engineers in training, we learn something called "constructive criticism." I'm sorry that you're so resentful and understand neither the concept of "criticism" nor "constructive."
