I am always amazed when people talk about pressure in the hose without referencing the size of the gap between the molds. 50psi can mean a lot or a little force is applied depending on the gap. Pressure on its own means nothing. 100% Agreed! That's actually what I was trying to address in the initi...

It would be interesting to know more about why he took this view. In reality, wood is a somewhat im-perfect core material, so it's a bit of a surprise. I think the igneous skis put is best ... but I can't remember what they said. IMHO ... the interface between the core material and the matrix is so...

or you can actually build something and enjoy skiing it Sigh... I think it should be reasonably obvious that different people have different objectives. If that's yours then more power to you. It isn't mine. If I just want something to enjoy skiing then I can walk into a ski store and grab whatever...

but I have a long-standing preference for metal skis. Being able to procure Titanal or an acceptable substitute is therefore a "must" for me. Sounds rad, but unless you have a trust fund somewhere burning a hole in your pocket, i'd suggest getting a solid year of ski building under your b...

Does the cat-track not achieve some of this? High contact width on the top side then smaller contact width on the bottom side where it presses on the topsheet. Pressure is higher at the laminate than in the airbag. [Facepalm] Yes, it does. That's what I get for posting at midnight. The cat track is...

I've tried to search for this in the forum but this is a bit of an oddball question (it's difficult to figure out what terms others might have used to describe the concept) so I may have missed it. Sorry if this is a repeat. I'm investigating the possibility of making my own skis, with the following...

Nice bit of research! I was wondering what FEA platform you intend to model within. Have you taken a look at e-fea. It has a ski model within the program. Are you thinking DMTA testing. I hear its a cheap and accurate method and would give an insight into model you have already sectioned. I have no...

Sorry about the double reply, but... Then you really have to adjust your cores for the thickness of metal you have. Better have a cnc and do at least 5 pairs all the same to get the flex dialed and then there's the ride to consider. When its all said and done you are talking thousands of dollars and...

I spent three weeks on this last year. I visited countless aeronautics forums learned all about chromate and PAA treatment as well as some others. I found a aeronautics supplier company in socal but coming up with the right thickness is tough. I think they had 2 that fit the bill but that's specula...

Are you able to purchase the other alloys? As you know trying to buy titanal is (near) impossible. That's of goal of mine also this winter is to make a race ski using AL alloy. I've found some perforated AL online, I think the perforations will aid in bonding. It's not cheap so the search continues...

I've searched the forum for this but couldn't find anything relevant, so... Back in the 90s I had a pair of 213 cm Wolf SGs (the bright yellow ones with fairly deep sidecut), which were great all-mountain skis for their day if you drove them hard enough. They were unusual for SGs in that they were v...

I'm a lurker who's considering taking up ski building as a hobby, but I have a long-standing preference for metal skis. Being able to procure Titanal or an acceptable substitute is therefore a "must" for me. After searching through a bunch of threads I've noticed that a lot of people are i...
