Haha, thx MontuckyMadman for that reply; it really made my morning at work so much better :D Guess I was thinking too much about myself cause I have all the stuff left over from my final year project from college, plus a spare vacuum cleaner. It would be a nice way to save 200E on a decent vacuum pu...

Hmm, maybe it would be an interesting solution if you can get a good enough seal on the bag. I think a valve could be used to keep the bag under vacuum, and by placing a pressure sensor inside the bag (placed before the valve), one could build a pressure switch so that the vacuum cleaner would only ...

I remember I saw some nice molds made from resin by a guy who used to make carbon fiber model aircraft gliders. I think he CNC-ed the positive out of wood, and made the negative mold by resin casting. Only problem is that I don't think a resin cast mold would hold up to a pneumatic press, and I it's...

Critique my first design
So here it goes. http://www.filedropper.com/albatrossv21 Hope you guys can get the .dxf file from the above link. I haven't thought about the core yet, but I'm thinking about something like 2.5-13-3.5, built from laminated ash. I have the impression that tip and tail rise are a little bit to high, b...

I'll try to look for some formica; never worked with it yet. At first I was thinking about using some 0.3mm aluminum sheet, but I don't really think I can bend it precisely enough to the mold shape. Good to know that the mold surface has to be as close to perfect as I can get it; since you said that...

You're absolutely right about it twizzstyle; I think I just got too excited in the moment thinking I could make things even more simple. I'll have to think about what material to use so it can easily take the contour of the mold, but still offer enough support to get the bases flat. I guess it's a l...

hmmm, that seems very interesting interesting. It would save a lot of work and fiberglass/epoxy. Nice idea with the plastic packing tape and mold release; will have to remember that one; I also guess it's very easy to just replace the tape once you pull the skis form the mold and you end up with a n...

thanks for the reply and the link sammer! Do you think it would be an ok solution to use mastic tape on the mold surface and just sealing off the top part of the mold, so there would be a smaller volume of air to remove, instead of sticking the whole mold in a bag? Or am I just asking for leaks by d...

I know about the issue of polyester dissolving polystyrene; I will go with epoxy and I think it will be a nice opportunity to test the resin system I will use for building the skis (though a little expensive maybe). I used to build model aircraft wings with some friends by using the same technique a...

I'll do more research on the modified nippers; I think I remember seeing something around here that involved cutting a small trench with a dremel so the tang of the edges would fit. Glad to hear I'm not the only one who isn't so blessed that offpiste skiing automatically means powder. I actually enj...

@skidesomnd: I was talking about bending the edges at the tips and tails with the base flat, before bending them for the tip and tail radius. I was just thinking about bending them around a flat MDF template while hot and then trying to restore the temper by quenching them. @twizzstyle: I'll give it...

Thanks for the reply! The stuff I was thinking about is actually green :P. I live in Romania, and only did some research on the internet regarding insulation foam, as right now I am doing a 3 month internship in Ireland; that's why I only predict starting the project in September. Anyway, it's a nic...
