I think this forum is for people to share their experiences and ideas to help each other build better skis and snowboards. This forum is also a great tool for research. I personally have gained so much knowledge from searching this forum alone its not even funny, and all your initial questions I'm s...

I'm not sure how involved you are in the whole urban jib scene (I am not), but from what I know a stiff ski is NOT a good jib ski. And a 120 waist width ski is not a traditional park/jib ski dimension either. For the application you are suggesting, I'm not sure how those dimensions are going to fit ...

That's good to hear. I've got a pretty hefty amount of rocker, which hopefully will help in powder as well. I'm expecting the tips/rocker to relax a bit, because I'm unfortunately not using a heated press.

Wow, I just saw the diagram of flatkick, and that's sorta similar to what I have. Does your mold have as drastic of a kink in the tips and tails as the "flat kick" diagram below has? (Where the "Wahpow" arrow points) And how do you feel like it effects the ride? http://grousepark...

chrismp- I was wondering when someone was going to notice that. After many attempts with the router, I couldn't get a uniform curve across the molds. My router is old, and just about only will cut base well. The way I did my tails is with a table saw of all tools. It is made up of laminated 2x4, but...

Here is the nearly finished press, despite missing a few bungees and needing adjustment to the cat track. Recent paint just put me around $125 final tally. (Angle iron was free). Tested to 40 PSI deflection was around a 1/16 of an inch with the tape measure test from ground. http://i305.photobucket....

Skidesmond- I actually got the idea from my press from your thread, and partly from a thread from a couple years ago that involved TJI's. I really like the way yours is configured, and that how big of a cavity you have. Very Nice! Alex13- I appreciate the numbers and equations for the beams, I will ...

I have tested it up to around 25 PSI, and have no visible deflection so far. I'm going to get a regulator soon and a safety valve, and will report back on pressure once that's complete (my compressor is antiquated and not sure how accurate the gauge is). I couldn't find any numbers on the TJI's to c...

TJI press

Over the last couple of months I have begin to assemble my snowboard press, and now I am close to being finished and preparing for pressing after many months of lurking and research on this forum. I have built it with TJI 460's (Not quite sure what that means except they were the bulkiest and talles...

Palmer has been making honeycomb-core boards for years. If I remember right they started out with honeycomb in non-critical areas but the latest is 100% honeycomb (nomex).
Check it out.

Check the "how to" sections on the main page. Most of your questions will be answered there in the future. As to your questions a.) you do not have to use a topsheet b.) you probably will have the texture of fiberglass on the top though c.) If you use the top sheet from here it will be smo...

I had this problem as well. For me, the answer was to make the core profile flat at the tips for the first 4-5 inches, if not more. If the top board you are using will not bend to horizontal you might want to try using a thinner board. That being said I understand that others might do it differently.
