ED-SKaR Posted December 7, 2013 Report Share Posted December 7, 2013 to about 200fps it isn't usable as it is now and lowering the weight of the hammer to drop the fps isn't really the way to go if you want to lower the fps you should restrict the flow of gas in the shells A far better way of reducing the FPS of a revolver is do reduce the gasflow in the firing valve, if you can find another valve that matches and has lower gasflow, or in the gas channel between the valve and the cylander.

teflon don Posted January 1, 2014 Author Report Share Posted January 1, 2014 hey guys, sorry that i fell of the grid for a while. i'm now studying in Sweden since august and unfortunately i didn't have tools and materials there.so i had to put this project on hold and forfeit the build competition as well anyway i'm back in Belgium for a few weeks and im back to building airsoft guns so here is a small update on the project -i milled the top flat and im building a top rib now ( i'm trying to cast it instead of milling it because it gives me more freedom) -i bought some bar stock to mill an under lug -and the new hammer is cast and there is just some final sanding that needs to be done PS if there are some guys here from the Göteborg region, let me know we can go airsofting together Link to post Share on other sites
teflon don Posted January 5, 2014 Author Report Share Posted January 5, 2014 here is where im at at this point, it already looks much better, but im not quite sure what to do with the under lug leave it like it is or mill some holes or something still have to solder it all together btw what do you guys think is the best solder for aluminium any thoughts or remarks ?

renegadecow Posted January 5, 2014 Report Share Posted January 5, 2014 Lookin good. Only thing I'd nitpick on is that the sights should sit lower particularly with that kind of rear sight (usually flush with the top part of what it's dovetailed on). edit: I'm having fun using lumiweld on aluminum. Zinc diecast on the other hand is a pain. Link to post Share on other sites
PureSilver Posted January 5, 2014 Report Share Posted January 5, 2014 I wouldn't solder it together, I'd glue it with some of those special aluminium adhesives that Lotus and the aerospace industry use - they're tough as hell and they don't mess up the finish, so you could have it all polished and anodized separately, and then put this glue on, clamp it together, bake it in the oven for an hour or whatever, and they'll be stuck like it was forged that way. It would need to be the last step of assembly, though, if you're planning on having it anodized, as I expect the chemicals involved in that process would react badly to contaminants like glue. The design needs more detail at the moment - milled pockets, slots, holes, something like that - but it's looking promising! Link to post Share on other sites
teflon don Posted January 5, 2014 Author Report Share Posted January 5, 2014 i thought the same thing about those sights but they came out of ruger mk1 and on the mk1 the sight also sit on top of the frame in the mk 1 the rear sight sit even higher in regards to the front sight i know glue is probably the smarter choice but as it sits now it looks like the rib and the underlug just sits on top of the barrel and im hoping that adding a weld seam will make everything flow more together for a more professional result im not going to anodize it, i was thinking of either giving the barrel and the drum a high gloss polish and duracoating the frame flat black or duracoating everything flat anthracite as for milling holes pockets and slots, im going to look at some bowling pin guns for some inspiration Link to post Share on other sites
teflon don Posted January 7, 2014 Author Report Share Posted January 7, 2014 i was thinking about the finish of the gun i tried every spray paint imaginable and almost nothing guarantees a durable finish, so i decided to go with something like duracoat i tried to look around a bit on where they sell it but i haven't found a shop that sells it do any of you guys know where you can buy it the cheapest or has anyone of you guys tried to make your own duracoat i think its basically a polyurethane resin with some color pigment and some kind thinner also i was think about engraving the barrel do you guys know if there are (relative) cheap cnc machines that are designed for small engraving Link to post Share on other sites
renegadecow Posted January 7, 2014 Report Share Posted January 7, 2014 When painting aluminum you need to use an etch primer. Link to post Share on other sites
Mike_West Posted January 8, 2014 Report Share Posted January 8, 2014 here is where im at at this point, it already looks much better, but im not quite sure what to do with the under lug leave it like it is or mill some holes or something Angle the front a bit maybe? And check how heavy it is. If it's too heavy, start milling holes. Link to post Share on other sites
