DIY Ski Profiling Jig

- In this video I give a tour of my ski profiling jig. It's the device I use to mill down my cores and give my skis a nice flex. It helps carefully and uniformly remove material from the tip and tail while maintaining a thick waist.

Seriously bro. New sub here! Thank you and I am watching you for trying a alpine snowboard build! Thanks again!!
Thanks dude! Good luck!
This is so great! Thanks a lot, time to start building. ;)
Nice! Feel free to shoot me more questions if they pop up.
@@redbarrelskis3361 Hi, I sent you an email for further question. ;)
@@MountainsEye Got it! Milling the core with sidewall... Tricky stuff.
How about using bolts on the hold down pieces that hold skies down. Instead of all the holes, just install threaded inserts that the bolts thread into. Moving the hold down pieces would be faster too.
Hey,
Very cool Video.
I´m from Europe, and i think its really difficult to find Informations about "how to build Ski".
Thank you very much for your Videos :-)
That's the exact reason I started making video's! Not a whole lot of great info out there on what is a relatively complicated process. Glad you like them!
@@redbarrelskis3361 thank you. Please go ahead with this 🙂
Nice video. I’m wanting to start making some skis. Any tips one where to begin on getting first equipment
Thanks! Oh boy getting over the hurdle of your first pair is definitely a challenge. I’d focus on the woodworking tools (planer, jig saw, tons of clamps…) then ski press and finally CNC. Good luck!
Amazing job man. I was already struggling to get one CNC for core profiling... maybe it's a good idea to give a chance to your system! it really looks great. Just i was wondering how precise are you with the rails when an exact core is designed in Fusion360 for example. would you use separeted thinner layers of wood (1mm for example) and adjust to the measured thickness on several points?
Again, congrats for your job !!
Thanks man! Its pretty accurate, I take a set of calipers to it when I get done. Honestly I don't usually have a model to compare to. I lower the router to the desired thickness for the tip, set the stop. Then bring it back up to the surface and mill from top down in steps. I make the tails a little thicker than tips. I have a couple projects on my to attempt list. One is making the shims and riser parts for the profiling jig on the CNC. I'd have more more control over lengths and transitions... Also one day I will try profiling my core on the cnc. Let the robot do the work! lol. Cheers!
@@redbarrelskis3361Hi there, I just binged watched all your videos, as when I get interested in something I take the dive. Your technique for everything is very precise and symmetric. I own a custom cabinet shop and obviously I love skiing. Creating a pair of skis has something very appealing to me as it would be a challenge and meditation at the same time. I have a 5x10 cnc and would love to put it to work. I understand why you use the sled to create the tapers. You mention here using the cnc in the future to do this task… by hand with your sled the straight cutter is parallel to taper. A cnc would need a ballnose cutter since the head is perpendicular to base? Then not only would this profile be managed in the Z-axis at the same time… I am sure it can be done, but have you gone down this route yet is my question. I am not at building skis yet… but you sure have my attention!
Really nice videos and great work! Why not using your 3D CNC router to profile your ski?
Thanks! Yeah great question. Mainly time. I use a bigger router, with bigger bits, on the sled than the CNC. The CNC is just a hacked X-Carve. Not the most industrial one on the market... So I just would hate to push it too hard or make a program that takes a crazy long time to run.
Hey, so I’ve watched most of your videos now. This isn’t a post about your profiler sled (sweet idea with the Velcro shims to adjust to each core thickness btw) but I was planning on making my own press and was wondering how you adjusted the length/tip &tail rise/ camber in your press for both skis and snowboards. I was planning on constructing the press put of wood (I don’t have access to I-beams, and they’re expensive). Just wondering how your press is adjustable enough to accommodate both radically different sizes, camber profiles, and tip and tails. Best
Nice, thanks man! There's a couple adjustments I make when going from long skis to say a shorter snowboard. The main one is the mold. I have an adjustable lower mold that has a tip section, tail section, and middle section. I loosen some threaded rods and slide the tip/tail closer to middle. Then I also have a adjustable upper mold, more or less. Its a mold I cut into some sections. I add/remove sections to make it close as possible to the right length. Also I remove/add pieces to my cat tracks depending on the length. The bladders take up the rest of the slop. Hope that helps!
Hello, your videos are very interesting, I have a question I am thinking of making a snowboard, my concern is how to outline the core, the rail system with a router works well, I want to leave the ends at 2 mm and 6.5 mm the center, I could have a core professional with this system. thank you
Hey dude. Thanks! That core profile sounds pretty good, maybe a little thin. I like stiffer board in general though, so maybe I'm bias. From a manufacturing perspective its kinda tricky to get the tip/tail down to 2mm. 3 - 3.5mm is easier on the router sled style jig. Also the binding inserts are going to get close to your base material at 6.5mm. On snowboardmaterials.com the inserts are between 5 and 7.5mm long for
You have CNC, why you hand profiling the core?
CNC has smaller router and would take longer... but that is a future goal!
What kind of bit do you use?
Just a 3/4" flat ended bit. Sharper the better for when you dig into the plastic sidewall...
Great content! Why do you use jig for profiling when you have cnc? Curious :)
Thanks! The CNC really only holds up to a 1/4" bit efficiently. Over that and you have to go super slow. I just don't want to run it for like 6 hours... I use a bigger router on the sled and can put much larger bits in it. Also I built the sled before I had the router, and if it ain't broke don't fix it.... Cheers!
@@redbarrelskis3361 100% rational man, thanks! I was wondering how can I deal without cnc to cut off the core but I figured it out! I will do the layout in snowcad or something similar, order polyacrylic template, rough-cut the core on the band saw and trim with the router, how does that sound for you? would you do the base the same way or hot knife around the template?
That's a great plan. What I'd recommend is making the acrylic template to the shape of your ski. Then making a wooden copy from some plywood (so it won't twist or bend.. been there). Sandwich base material between the 2 templates. Then use a rabbit bit and pattern follower bit to 'shrink' the plywood to the shape of your core. Then cut your cores. Don't forget the thickness of the metal edges..
@@redbarrelskis3361 Your efforts are a blessing to me, both video and text content. Appreciate that a ton. If you ever need some help with marketing or SEO, I'd be happy to give back! Great idea with the plywood, it will be thicker, probably easier to rest the bearing of the router bit. Cheers! ps. I wish I lived in Colorado!!!
Hello, I have built a similar set up to yours. What kind of router but are you using?
Nice! Its a Dewalt 616 with a plunge base. I use a 3/4" double flute straight edge bit. I typically run about 3 depths to get from ~10mm to ~3.5mm, climb milling to reduce the likelihood of ripping off the sidewall. Good luck!
Hey JD are your cores continually thinner towards the tip and tail or is there a flat spot at their thinnest point? I'm trying to figure out what shape to make my router rails
Good question, depends on the type of ski I'm making. Generally speaking though they do flatten out just a couple inch's away from the tip and tail spacer. Some day I'll replace the shims and binding platform spacer with a dedicated profile. For a carving ski that would be nice. For a park/all mountain ski I don't think it matters too much. Good luck!
What bit did you use?
typically a 3/4", 2 flute, flat end router bit. Recently though I bought a indexable 1" router bit I'm going to try out. It was this one: www.amazon.com/gp/product/B08SKYYN7P/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1
