Re: Divide Rides

Man those look awesome !
Should have called and have a drink with you, I've been in Terrace for 3 weeks at my buddy's by Lakelse lake, touring the Shames BC because the hill was closed..

Re: Kids Pow skis

Just a short heads up : V2 is ways better that the first pair. Dimensions are almost the same (went 20mm longer because my daughter could handle it). So now 118cm long. Full poplar core, 90mm underfoot. 1.7 - 7.3 - 1.7 core thickness (this time I knew exactly where I needed maximum thickness for the...

Re: Round Top skis 19/20

Great job !
I might have something for your wires when you come for your templates... pretty sure I have some cable glands left from when I wired the solar panel on my van... I'll check !

Re: Round Top skis 19/20

Sorry I don't have any source for fiberglass, I bought 20ish rolls of 22Oz triax from a manufacturer a few years ago, sold half of it so I still have a lifetime supply of fiberglass considering how much I build skis/boards. I can definitely help you with CNC cut templates. PM me of you have specific...

Re: Round Top skis 19/20

I'm in Sherbrooke, curious to see your vacuum setup !
If you need Epoxy let me know ! Not that I have some for sale but I need to get some, maybe we can get a larger qty and share, I have contacts for a nice supplier in Ontario.

Re: Kids Pow skis

I won't use any tipspacer, I will just pour PU sidewalls all around the skis, including tip and tail... was thinking going down to 1.5mm. The 22Oz fiberglass triax is pretty thick. I agree that core thickness has more influence on flex than fiberglass but my daughter being such a lightweight I think...

Re: Kids Pow skis

Should have come here earlier :-p I made the core 8.5mm thick (where the bindings are), down to 2mm at the tips. No tipspacer, just PU all around. i was worried about the screws.. shouldn't have been I was hoping to be OK with my 22Oz Triax and a core ways thinner than usual (for my own skis) but th...

Re: Kids Pow skis

Good point on the length of the thicker bindings area ! You make me reconsider my choice, I might go with an 8mm max thickness, especially considering I only have 22 Oz triax... better be softer than too stiff ! If only my snowboard inserts were M5 instead of M6 I could use some on such thin skis ! ...

Re: Ben_Mtl 2014... skis and CNC

That's correct there is no connection between the 2 sides of the gantry under the table... but it's not needed since I use 2 steppers on the X axis. Actually the fact that there is some torsional flex for the gantry is OK because I can then check/ adjust how X and Y are perpendicular every time I re...

Re: Ben_Mtl 2014... skis and CNC

I've built it myself, design was somehow inspired from another CNC from CNCZone (Platform CNC, IIRC..) I designed all parts myself according to my needs, had them fabricated locally, and assembled this amazing adult LEGO :)

Re: Kids Pow skis

I'm in the same process for my 7y.o daughter. I'm building 116cm long skis, 86mm underfoot with 8.5ish meters turn radius. She's not into powder skiing yet but she wants to... so I build this pair to complement her "store bought" resort skis. I too am still questioning about the stiffness / thicknes...

One thing to keep in mind when using carbon that most people don't realize is that carbon is not much stronger by weight than glass if at all. It's almost 3 times stiffer, but not much stronger and fails with much less elongation. I made a few snowboards with a light all carbon layup and had the fi...

thanks for the link, I just sent a message to Bcomp with all the data I have regarding my actual process VS the "new" materials I have on hand and am planning on using... will see what they suggest. Usually you try to switch one material at a time to tweak you process and keep consistant results.. t...

back from the dead, fun leftovers to be used !

Hello everyone, It's been a while since I've been here.. and even more time since I built my last pair of planks.. After I built my first pair, 10 years ago, I was taking small orders for friends and such because I liked it... the materials paid for themselves I was was paid by having fun doing it.....
