Hi David. Well, sorry, but the test chamber has been on hold for a while.
I'm going over to the iron shop for pricing on my stainless ballast tanks this
week, and I'll try to get the flanges needed for the window. I want to be able
to video the test with a good view of the unit as the pressure builds. I have
everything for the chamber except the two flanges. Once I get them, it won't
take long to weld it all up. The testing Les did sounds really good. As for the
salt water test, relating to the difference between salt and fresh, I'd be
surprised if the difference was that great. I wonder if part of the difference
was that open salt water has more debris in the water, and any large body of
water like a harbor or ocean or whatever is bound to have a lot of background
noise from things like tiny creatures clacking away, possible boats within the
area, waves slapping against the shore, and generally the ocean is a pretty
noisy place. Sound carries really far through water, and with Les testing that
system in a pond covered with ice ( BRRRRRR!!!) it would have been a pretty
quiet place to test in. I'll get on that chamber, and again, sorry for the
delay. Frank D. A Good Credit Score is 700 or Above. See yours in just 2 easy steps! |
