And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
a long time ago, I helped my Dad out on a concrete job. redoing a guys driveway. he was a patternmaker at the old Philly navy yard ( yeah, this was a LONG time ago ) anyway, instead of getting the 150 bucks that I was to be paid for working like 3 days. I got a bronze cannon that the guy had "made" while at the yard. still have the damn thing too. about 20 inches long and weighs over 40 pounds at least. shines up great but is a lot harder than regular bronze that for sure.
I believe that the theory of non-cavitation prop blade shape was mostly worked out, but thanks to some unauthorized classified disclosures, and Toshiba selling the milling machines to the Sovs in the 1980s, here we are.
Obviously a bronze alloy. However, that’s not one of ours. It it was the screw would be covered with a tarp at ALL TIMES when it’s out of the water. It Roosky or ChiCom but not Frog.
Silicon Bronze

DeleteWorked in a Navy shipyard in the 80's. Back then, we always kept the sub propellers covered. I think the curves were considered classified.
ReplyDeleteUntil everyone figured out how non-cavitating props work.

ReplyDeleteI believe the prop shop is still functioning at the Philly Navy Yard. One of the fw shops still functioning at the yard.
