Great work sammer.

more progress from the dungeon...

Got the skis cut out and semi finished.



Even with the tip bender edges are still slightly out of plain.
Gotta work on cutting them to length better.



gluing edges running side down (traditional) edge fit is pretty good.
Once they get a proper base grind I'll post a better pic.



No camber just a flat spot under foot and rockered tip and tail.



Core to tip spacer transition turned out pretty tight.



Still gotta get a few coats of p/u on them.

I missed the mark with the frog, gotta mark out where the ski actually is on the mold, once the veneer is on the ski kinda disappears.
still all there but... oops



some details;
used 19oz triax 1 layer above and below the core,
some 22oz for binding mount,
3 24k carbon tow stringers above the core,
veneer is walnut with a skim coat of epoxy
Stained it after a bit of a sand with red oak stain.
Stained the maple sidewalls to see what it looked like
Small amount of heat 100f from my electric blanket, just to get everything curing.

All in all turned out OK.
Only minor cosmetic issues will definitely get those worked out for the next pair!

Got edges bent for the boys skis.



His cores will hopefully get sidewalls tomorrow.
Will probably use the orange base as tip spacer, it's pretty thick and abraded and treated both sides.
They're gonna have to be pretty thin at the tips and tails so should work out alright

To be continued...

Nice work Sammer! What are you using for the frog graphic?

Yeah really nice. I need my graphics to come out that clear.

Thanks guys.
Frog is just printed on plain paper with my old inkjet printer. Cut out with an exacto knife.
Held in place with an epoxy skim coat.
You can see I actually sanded through the frog on his left back foot, and his right shoulder and thumb?
I think it's just a matter of picking the right colours to make them pop.
Tried printing on veneer yesterday but am out of blue ink and the veneer doesn't want to feed through the printer very well.
Might give it another try later.

Very very nice!
I like the transition between tip spacer and core! Thats a indication of sucess! (in my book)

Nice work Sammer (as always )

Printing on veneers can be tricky ... I think the old printers used to have a 'card' setting, closest now is 'photo'. I tend to ensure a stock of paper is behind the veneer, helps with the feeding. Once it is going - no worries.

what 19oz triax are you using? Have you used any in the past? I want to switch to using 19oz triax and carbon fiber from Soller composites to make the skis a little bit lighter and snappier.

Sammer, amazing. You do incredible work with what you have. Way to go. Those look SO awesome

shopvac...don't use 19oz and CF or you'll end up with something so stiff you'll never ride it. Imo.

agreed.

shopvac... 19oz is vectorply E-TLX1900 I bought from headmonkey when he was getting out. Ya built a few pair with it now.
Same as the 22oz in the 45's but lighter in the 0 so using a bit of CF to make up the difference.

brazen... thanks I try
Need to work on the finishing, might try the pre-poly trick next time.
and skis are not quite like boards you can use 22oz and CF and still make a noodle ski if your core's too thin.

sam

thanks for the advice. We have used some triax from Raka that they sold us as "22 oz" with carbon fiber and they are pretty good for the flex. I don't know if the triax glass is actually 22 oz though or if it is heavier. It has a mat and it is pretty beefy. How much material do you actually weight to get the 22oz peice? Is is 1 yard by 1 yard or what? I am not sure I even have that much left so this might not be possible but I can do some math with a smaller piece if I know what I should multiply it up to. I think I have seen a post somewhere that describes the Raka 22oz as closer to 25 oz. Anyone done any real measurements with their glass?

yeah, it's ounces per square yard. so weigh a 1yd by 1 yd piece.

1st of the boys skis are in the bag.
Had to go back to the old school for these.
Cores had to be pretty thin. He's a hard core skier but at 7 still pretty little.
Used the orange base as tip spacer so cores are down to close to 1.3mm and about 5mm at the waist.
Got materials all prepped last night



Cut out the first base and got it taped into the mold. Glued in core locators.



Like I said, going back to plastic sheeting and mastic tape.
He got a chance to do a tie-dyed fabric for the top sheet at a day camp this summer. Definitely one of a kind graphics one this pair!



If I managed to get all the air bubbles out you should be able to see the construction in the white parts of the fabric.
As these skis are full rocker I put a couple of carbon tows on top of the core.

Of course don't forget the frog



Cores are aspen with 1 maple stringer down the middle and maple sidewalls.
Used 19oz triax one layer below and above the core and a small piece of 22oz for binding mount.
EMV043/ECA032 I'm still not sure about that stuff, it's so thick even heating it took about 500 grams to get everything wetted out.
I think that's a lot!
I bought some EMV045 (should be a bit thinner) I'll try that soon.
Didn't want to experiment with something this important!
Just got a call from the boss, gave me the day off tomorrow so I might get the other ski done then.
More as things develop

Nice!
