cores are fun. we use a profiling jig like mark made in the photo seen below: http://i70.photobucket.com/albums/i99/neclassic/snowboard/snowboard002.jpg http://www.skibuilders.com/phpBB2/viewtopic.php?t=992&highlight=crib+mdf We add shims in the front and back to help keep the profiler from losi...

We built another pair last week. Montucky made us 4 new bags that work great. It seems much easier to get the 4 bags on and off and they are slightly smaller in circumference which is better. Thanks again. The new bags: http://lh6.ggpht.com/_WWlE16CVFao/S5CJlvv7NBI/AAAAAAAACHU/ArY5LQzs9-s/s800/IMG_3...

cheap wood could be pallet wood you piece together. When I started looking for pallets they were everywhere and free. I know Kam built a pair like this and the skis I am on everyday have pallet wood cores. I probably have 30-40 days on them now. They have some cherry, oak, and poplar in them. I thin...

damn that is awesome. I like the small channel you have for getting into/out of the main channel for going around the ski. very well thought out and also it could easily be modular using the same port and vacuum.

we have had good luck with sign makers. Both of the companies we used were listed that way. Possibly a pleixglass place might have one also. The place here had one but it was too short in one dimension for continuous templates. Good luck.

damn those are purdy. Love the wood veneer. Certainly wood has some nice stuff. We are working on a pair with a new tip that should come out a little different than the rest we have built. Did the ash cores handle better because the ski is heavier and possibly more damp? I am curious because I reall...

hey montucky, we just sent you up some base material. I hope you get that soon. I would be willing to provide a few more meters for testing if it doesn't work out. Let me know. Heliski -- could you post some photos of your bases that you have cut out with this machine? I am very curious to see how t...

Mongo, great post. Any news on the VDS? I have looked at McMaster and even tried to order something I thought was going to work, but it didn't. Still searching here ...

Good eye. I am standing on the clean air side of ARO and the photo is looking back towards station. I was there for a year 06-07 working for NOAA. Did you ever work with Sven? I know a couple cubers. That project is pretty freakin' huge. I still don't know what the heck a neutrino or a muon really i...

Here are Jekel's FEA photos. Thanks for doing this for everyone. I believe he is using 40psi to do all of his analysis. 12" tubing with 1/4" wall thickness http://lh6.ggpht.com/_WWlE16CVFao/S2rsCeqS5AI/AAAAAAAACGI/kX6oNtvqhts/s640/12%20inch%20quater%20wall%20displacement.jpg 12" tubin...

skis look clean. Nice work as usual. Do you get any deflection when pressing? A lot of your earlier photos don't work any more. If I ever build another press, it will be very similar to your design.

does it always happen in the same spot? Is your bottom mold perfectly flat? We get epoxy on our bases but it is usually very thin and gets taken off with a base grind.

I saw that post of TGR too. Looks very smart. I bet profiling the cores would be a little trickier. Do you think the 13" planer/crib method is out? I would think the planer knives would be ruined where the metal strips were added. I guess you could get a bit that would do it with a router or on...

just curious, do you guys think this was only because of the fg weights (and choice of glass) or does it have anything to do with the horizontally laminated birch plywood he uses for his cores? I know a couple builders on here have used horiz laminated cores with good results (but they probably used...

Another huge thanks to montucky. You are totally correct. The first set of bags, which can be seen below in the photo used two bags - 36" long by 44" circumference, made 12 skis (6 pairs). We pressed a single ski anywhere from 30-52psi with them and it always did a great job. These bags we...
