Bladder diameter
Hello ski builders,
I just picked up a fire hose long enough to go across the press twice. The bladder is only 4.5” in diameter without air. I have not inflated the fire hose yet not knowing its diameter with air. My press diameter is 15”. Will the bladder be large enough or would you suggest buying another hose concluding with three fire hoses going across the press?
Thanks guys!

I mismeasured the fire hose diamater; both bladders are 4" in diamater deflated. I am going to order another fire hose that is 4" in diamater from McMaster Carr. So I am going to end up using 3 bladders that are 4" in diamater across a 16" diameter press frame. I'm hoping this will be good enough!!
Thanks
Thanks

Three wide
Tell me how it works out for you elk. I was given some free, serviceable, extruded 3 inch diameter firehose. I could make a 15 inch bladder. Thinking about using it, but I think I would prefer two 5 inch diameter hoses.

Even if you only have a 1" gap for the hoses to inflate in your contact patch is going to be tiny. Like 6" maybe, if you have 3 hoses. You'll be lucky to get 50% pressure at the laminate. Therefore, if you're inflated at 80 psi, you will be lucky to get 40 psi at the laminate. 40 is ok, but you better make sure your bladder and fittings will be able to handle 80.

50 psi no gaps flat is what you want no gaps and flat
