I got some materials from a friend who works in a ski factory, including topsheet foil. He told me that I need to spray thin layer of colorless varnish (laquer) onto the foil, because otherwise the it won't glue to the rest of the materials. Is that true?

I am building a press and came across such a problem. As it is hard for me to get 2 pieces of fire hose with the diameter of 110mm, I plan to use 4 pieces of fire hose with the diameter od 52mm. The air capacity inside will be nearly the same, only question is will it work and create enough amount o...

Theoretically if I manage to make leak-proof bladder it should work. The compressor is indeed small, but I plan to make a very small gap between pressed skis and upper mold, so the volume of the bladder isn't that big. Then small compressor should inflate it quite quickly to the desired pressure. Th...

Thanks a lot!

Do you think that a compressor for inflating car tyres with 250 PSI output pressure will do for inflating the fire hose? I plan to inflate the hose and disconnect the compressor from it. Won't this kind of compressor be too weak? What do you think ?
