just a thought on lenghtwise deflection of the molds...maybe it's because your hoses are too big. we're going to use five 3" diameter (4.3" flat, they're called firehose type B in europe) hoses that exceed the width of the mold by approx 1" on each side, which would support the outmost parts of the ...

that's pretty much what we're building at the moment. just without the mdf strips to make a cambered mold...we just use a flat formwork boards (plywood) to get a flat base between the bindings (very similar to the capita horrorscope snowboards). are the tip and tail blocks in this drawing adjustable...

i trim the paper to the line with an exacto knife as well, but i don't glue it to my mdf boards since they're too thick to get a proper surface. i glue it to a thin plywood board that i cut and sand to shape and then use it as a template for my ball bearing router bit. i've found that it's easier to...

awesome, so glad that it worked out for you too! my biggest concern was that the mold could snap in two pieces lenghtwise if you build 2 skis at a time. but i think your 2x6 really helped prevent this. i made a little illustration ;) http://skibuilders.com/cpg/albums/userpics/10013/normal_press.jpg...

i guess you used rice paper for the graphics. well, there's no way to keep the unprinted areas of the paper from turning transparent.
i don't know how it would bond to the epoxy if you printed the rest of the paper in white though.

great video guys! i'm planning on using a press frame from MontuckyMadman as well :) i have just one question...in your video it looks like the fabric stretches out quite a bit under the pressure of the bladders. is that just some slack in the tubes or does it really stretch? (i guess that would red...

i don't know any way to seal hemp fabric, but you could try building cap construction and/or make the hemp layers a little narrower than the ski itself, so it gets covered with epoxy (i guess you'd have to use vds rubber all along the edges to help the layers bond and fill the voids from the lack of...

@Adroit707: could you explain how you designed the rocker/camber shape in your CAD program (which one?). did you just approximate the shape by looking at the NV boards or did you have any exact values? i'm planning on doing sth similar with the burton hero, so any advice on how to adapt a rocker sha...
