Hello all,
After reading Helmut Berghaus' website (chap who built a Krick U-25), I found out about his method of testing the water-proofness of his sub's hull (I assume the Krick kit doesn't not have a wtc, the hull is a dry compartment; dryhull) he did this by installing a syringe on top of the wtc cover and a bike valve on another side of the wtc. By using a bike pump and pumping air into the wtc through the bike valve, the air fills up the compartment and eventually builds up pressure to push the syringe piston outward, indicating that there is no air escaping out. However, if the the opposite happens, it means that air can escape out. My thinking]http://www.subcommittee.com/forum/icon_biggrin.gif[/img]
Wonder if anyone has ever tried this and proven that it is useful. I have a 4 ft long u-boat to be tested and a bathtub might be too small to test it in. I just want to know if this is useful in testing the wtc on dry land, without getting your feet wet (I like getting my feet wet, this is an exception... nearest lake or pond is 4 miles away from my house )
Thanks for any help!
