![]() ![]() According to Ruger's Jay Jarvis the phenomenon was a combination of rough usage and stress corrosion cracking. Currently, Ruger catalogs models in.44 Mag. The Redhawk went into production in 1979 and there are known instances of early guns (hard to state a year or serial number range here) up until around the time of the GP100 development in 1985 where the barrel shank of the Redhawk would break off. Since its introduction a number of variants have been produced, mostly resulting from changes in sighting rib width, hammer pivot tab location and ejector. In 1984, both.357 Magnum and.41 Magnum models were brought out, which were produced through 1991. What is the value of a Ruger super redhawk 44m double action revolver serial number 551-07478 100-1000 USD depending on specifics. Originally issued in 410-series stainless steel with a walnut grip and a 7 ½-inch barrel, the Redhawk soon became available in a 5 ½-inch barrel length and in blued steel. ![]() ![]() Other changes included a new cylinder latch system interchangeable front sight blades with different-colored plastic inserts and the use of a single coil spring to power both trigger and hammer. Also new was the Redhawk's offset ejector rod, which permitted more meat in the frame around the barrel threads as well as the use of a larger barrel thread designation, both of which increased gun strength. Ruger went to a cold hammer forged barrel with a stainless steel shroud/sleeve on their Redhawk a number of years ago. So, putting two and two together, and remembering that you are reading this on the internet, this may/may be part of background for the problem Redhawk barrels had back in the 1980's - not so much a case of "overtightening" the barrels, but a case of the chlorinated esters and/or chloride infiltrating and weakening stainless steel under high tensile pressure (e.g., tightened threads) leading to the barrel snapping under the force of firing.While front cylinder lockup in the Security Six utilized the traditional spring-loaded plunger that engaged the recessed tip of the ejector rod, front lockup in the Redhawk was accomplished by a crane-mounted front latch that engaged a slot in the frame in the area below the barrel threads. I also found the assertion that the Ruger problem with the Redhawks related directly to applying a lubricant with chloride to the barrel threads during assembly (during that early period). this is a phenomena called CSCC (Chloride Stress Corrosion Cracking)." This reportedly is a problem with certain stainless steels in particular. Poking around on the web, I read about several gun lubricants that contain chlorinated esters (one of them reportedly being Militec-1).Īccording to one citation, chlorinated esters when combined with "metals that are placed under high tensile pressure will and does lead to stress cracks. ![]()

The test results of the best antidepressant was on microcapsule powder with the variation of (1 g maltodextrin: 1 g gum arabic: 3 g patchouli alcohol).56 DAFTAR PUSTAKA Agni, S.T., 2014, Outcome Klinik dan Kualitas Hidup Penggunaan Celecoxib, Meloksikam, dan Natrium Diklofenak Sebagai Terapi Nyeri pada Pasien Osteoarthritis di Rumah Sakit PKU Muhammadiyah Yogyakarta, Skripsi, Universitas Gadjah Mada, Yogyakarta. Patchouli alcohol that will be used is coming from the distillation with the content of 42.37% which will be tested its antidepressant to mice further. In this research will be done patchouli alcohol encapsulation by using freeze drying method with maltodextrin, gum arabic and tween 80 catalysts as emulsifier. Maltodextrin and gum arabic are kind of good catalysts in the essential oil encapsulation. Encapsulation can be the way to resolve this problem. The essential oil is a sensitive and susceptive material towards high temperature, oxidation, UV light, and humidity which are able to cause the oxidative damage. Patchouli alcohol is useful for reduce depression by breathing is steam. Patchouli alcohol has several benefits in aromatheraphy field. Patchouli alcohol is an essential oil compound which obtained by fractional distillation of patchouli oil ( Pogostemon cablin Benth). ![]() |
