Re: Eliminating base warp....a guide.

Nice guide! this was one of the more frustrating things to get right for me - turned out that I wasn't bending my edges evenly enough when I was doing it straight to the base - which resulted in a warped base even though it looked fine when I was bending. what I like to do now is cut out the core an...

Re: Jonrezz’s Build Log

Thanks! yeah my setup is loosely based on chrismp's. I was thinking about modifying it like I drew in the picture below. I can understand the appeal of the hand router version's simplicity, and I'm all for simple solutions, but I really want to achieve that "step" look that comes from havi...

Re: Jonrezz’s Build Log

So I am taking a break for a couple of weeks from ski building due to an ACL reconstruction surgery I had last Friday. Since I'm stuck in bed with my leg elevated, time to update my build thread! So following up from my last post, I have rebuilt the last pair of powder skis that I messed up on my fi...

Re: Jonrezz’s Build Log

Ok Update time! I just cut out some FAT powder skis! now everything didn't go as planned with my new sidewall router and so I will be redoing this set. I think a wider center rosewood stripe will look better anyway for the redo, since these skis are so wide.. first off - here's how they look right n...

Re: Jonrezz’s Build Log

Interesting. My gut is telling me that the spreadsheet is underestimating how stiff those will be

I just took the 2.5/11.5/2.5 ones out of the press yesterday - I'll let you know what the result is in a day or two when I've cut them out!

Re: Jonrezz’s Build Log

Hey Comet - The book is "Skiing Mechanics" by John Howe. The chart says 30-60 N/cm typical stiffness for race skis in the footer note to the left - however - I have measured the deflection of the 6 factory made skis I have laying around - some race skis but some not - and they all fall wit...

Re: Jonrezz’s Build Log

Couple of updates! The laser is a bit scary haha! Ive been using the glasses that come with them, they seem ok. I look forward to incorporating the laser in a build in the near future! Regarding the sidewall router jig with the bit combination I found, I am pleasantly surprised! check out the result...

Re: Round Top skis 19/20

Congrats on your first pair! they look great! Did you perform the layup over the mold? I would recommend performing layup on a cassette on a flat surface, then transferring the whole thing to the mold once ready. I've tried it both ways and having it all flat while stacking the layers makes it so mu...

Re: Jonrezz’s Build Log

Thanks for the tip sammer! and thank you all for all of the help along the way! I'll give the roller a shot on my next pair that gets plastic topsheet. some additional updates: I have devised a new plan for sidewall beveling to allow me to get the "step" in the sidewalls like many brand na...

Re: Jonrezz’s Build Log

Thanks! So it’s been a while since my last post, but I’ve been hard at work! The snowboard from the time lapse came out with these crazy epoxy bulges!!! Oof! I must’ve used too much epoxy between the plastic topsheet and the veneer. Never again, I think for now on no plastic over veneer, oil based p...

Slalom Skis - First Test Trip

So I brought my first pair of skis out to gore mountain today!! These: https://i.imgur.com/aMzTmuw.jpg There’s plenty of info and pics in my build thread about them so I’ll keep the description brief, they’re 165cm, 12.5 m radius slalom style on piste carving skis. The core is maple/poplar, 2mm/10mm...

Re: Jonrezz’s Build Log

Thanks! Yeah, in hindsight, I kinda wish I brought them up further - the logic when I did it that way was that usually when I tune, the edges get a detune at the tip and tail anyway to reduce catchy-ness between turns. But now I’m wondering how long the skis will last without edge material protectin...
