vilas 477 Posted October 17, 2009 (edited) blued was SA 58, UK 59 and Czech weapons i think it is not blued i even not know if it is STEEL maybe aluminium or other light metal it is not bluing http://www.gunco.net/gallery/data/500/medium/0014.JPG it is bluing of STEEL as i read some time ago (I MAY BE WRONG) are you 100% sure ? are you metalurgist ? you work in factory or metallurgy on university ? or you took it from Wikipedia without photos ? i don't demean your answer, simply i doubt, cause i know bluing and i even doubt is this steel , cause look: this Polish grenade launcher has some parts black (phosphorisation) and some blue ? why for TECHNICAL reasons they are different ? cheaper is one process for all parts maybe those parts are from light metal, other than steel ?

Trapper 0 Posted October 17, 2009 The more blue parts and sights look pretty "homemade" to me. Especially because of the visible milling marks and the missing of rounded edges. Everything else looks like "original"/mass produced" weapon parts being hold in place by all of the others. Also it says in the description modular launcher, created by an acamdemy. ...ehm so probably I'm the last one who noticed finally that this grenade pistol is definitely a prototype by all means... :) Anyway I guess the black custom parts of the sights are from steel because they have to withstand manhandling and are blued like the original parts. The trigger case is made of lighter aluminum and anodized in blue because they were missing the right chemicals at this time or just want to be cool. http://www.aloxyd.ch/ Share this post Link to post Share on other sites

Colt45_GTO 10 Posted December 14, 2009 gun blue is basically an acid etch, it forms no protection to metal, it only colours it to almost black (very dark blue) its been used for centuries to decorate gun metal. blueing is a process that requires a perfectly smoth and clean surface. the best way to clean gun parts after the initial polishing is by boiling them in costic soda, this brings all grease/ chemicals out of the metals surface, the blueing then can begin once the parts are removed and dried. however when the use of boiling costic is used, it takes out that muck natural oil from the metal parts that the parts can immediately rust once out in the dry air. other forms of coating are machine black, parkerising and a few other finishes. once the blueing process is done the whole thing needs oiling rigorously so the oil penetrates the metal to form the protection. hope this helped mate.
