I built a wood press that is reinforced with metal. It does not noticeably deform when I press at 50psi. Based on the specs for threaded rods in terms of stretching and shearing I could go up to 80-90 psi if I wanted to. It has been through over 20 cycles and shows no signs of fatigue. I used two 4&...

G-man used strip type heaters in his press.

Lennart also used a similar set up.

During lay up it is easier to have the unplaned side down. This allows more of the core to stay in contact with the lower layers before going in the press. It is also easier to rout out the flat unplaned side of the core to allow for the edge flanges. edit: Hot glue is important. I lost a core (core...

I too tend to make my skis too stiff. On my next pair I'm using 20oz on the bottom and then 11 oz biax (45/45)on top. I'm trying to use the same core profile as I dial in what happens with different glass weights. My last pair used 39oz on the bottom with 20 oz on top and they ended up being as stif...

I use a single arc mostly because I'm still waiting for my cnc machine to be finished by odin. When I get a cnc machine I want to experiment with radii that change slightly and continuously from tail to tip. I envision having the radius get smaller towards the tip. Right now my skis are made complet...

I've removed veneer topsheets/composite layer on skis that came out too stiff. I used a thickness planer to remove the middle section of the ski. I then used a belt sander to get rid of the rest of the topsheet/composites on the tips/tails. This method took part of the core in the middle section and...

I think all gs skis have a 21m turning radius nowadays. I have 2 pairs of gs skis. The 188cm k2 mach gs from about 9 years ago are fairly soft from use but I'm not sure they were ever that stiff. I use these for early season recreational/training type skiing. They can be carved and will slide as wel...

K2's have carbon top and bottom, but its woven into the whole seamless fiberglass sleeve around the core, Are you referring to the carbon stringers running down the top of the cores I see in lots of K2 skis from the past 10 years or so? Does this mean there is another stringer under these cores too...

I use a higher quality dewalt jig saw with a combo blade to remove flash. I go through 1 blade per ski. The ski is upside down when I do this so I can see the edge as I cut. I then clamp the ski on its side and use a belt sander to sand out any protruding sidewall. Because I use a beveled router bit...
