You had soft tails? Did shifting the core back make much difference?

No I had the sidewalls not meet the core like that.
Yeah 1 pair with soft tails, I have been running a longer taper from the tip and thus putting the thick point back 5-10cm.
1 Pair I offset back but i felt like 15+cm of tip spacer was pushing it.
I have yet to do any cores with a flat area. That's next.

Everything is ready to go, still waiting for the topsheets, although I am told they will ship tomorrow. Fingers crossed.
I've got the fiberglass cut and ready to go, tip spacers cut, core locator pins (dowels) glued to the bases. I do need to do a little more routing on the cores for the edges since I shifted the cores back, but that's a 10 minute job I'll do tonight.
Also - I finally caved and am building a cat track. After so long of me arguing that cat tracks aren't needed, I'm finally giving into the fact that all production ski presses use them. I ordered the aluminum from Alaskan Copper Works in Seattle, and I'll be picking it up tomorrow. I'm doing 3/4", 1/8" wall square tube the whole length.

Stoke! Can't wait to see them come out of the press.

Yeah yeah, laugh it up
Ok a few new pictures.
Edge bender
Finished edges
The bamboo plugs I made to put on the bottom side of the inserts
This is what the pre-cured fiberglass/carbon fiber from Snowboard Materials looks like un-cut. The center stringer made a perfect line to cut the sheet in half.
Here it is cut
I had to lay everything out just to see how nice it all looked. Here's everything ready to go, sans top sheets
I bagged up some of the stuff just to keep it clean while I wait for the top sheets. Come on topsheets!! I'm ready!

hey twizz
everything looks great.
What is the theory behind precuring the glass/carbon?

Twizz....
Thanks for the precure pics.... it already looks stiff!
Looks as if it was manufactured for the snowboard ind.
Falls, the pre cure should be lighter and stiffer...it is wet out, then pulled into tension, then cured hard.

Exactly. It's pretty thin, so the idea is that there won't be as much resin in this ski vs a wet layup, just enough to adhere the layers together. Lighter/stiffer is what I'm hoping will be the result, but I won't know until they're out of the press.
Also by curing the sheet under tension the fibers are already sort of "pre-loaded" (bad term, they're not carrying any load yet). But they are all straight so much more efficient at taking up load (thats what should make it stiffer). The stuff isn't cheap though, at $17 a meter (four meters needed for a pair of skis)
That's why I'm making these two pairs in parallel, every step has been done exactly the same way and at the same time between the two so that the only variable is the fiberglass layers.

Sweet!
As always, I'm impressed of you(and others) getting perfect fit with the edges! I will now work on a edge bender.
What size are you using on the rolls on the edge bender?
