LexerHI im new to the site . does anyone have any experience with vacuum presses? Also how many CFM would be sufficient for this application. i have a pump right now that has 1.5 CFM seems weak.
I'm not sure of the exact CFM of the pump I use but I'm pretty sure its around 1.5 CFM given the price I paid for it and the new versions for sale from where I bought mine (i'll check the spec plate, next time I'm in the workshop). I have made ~20 pairs of skis using it with good results.
I've found the more important factor is getting a good seal on the bag, i.e properly using good quality vacuum bag, components and sealant tape.
There's a good thread here with plenty advice and information about building skis here: https://www.newschoolers.com/forum/thread/651776/Official-Ski-Pressing-Shaping-Building-Constructing-Thread
