Tampa-XD45 Posted March 17 Share Posted March 17 Is this the first or only 1911 to be made via two separate halves? https://www.thetruthaboutguns.com/gun-review-vudoo-gun-works-mobius-1911/ Quote Link to comment Share on other sites More sharing options...

ltdmstr Posted March 17 Share Posted March 17 Quote This allows them to use shorter, fatter, more stable tools to mill out the frame and rails, and get extremely consistent surfaces during the original cut. Um, sure. Hard pass. Quote Link to comment Share on other sites More sharing options...
perttime Posted March 18 Share Posted March 18 Not built quite the traditional way. The reviewer seemed to like it: accurate and reliable. Quote Link to comment Share on other sites More sharing options...
Don_B Posted March 18 Share Posted March 18 I don't know anything about these frames but with all the new technology they might be ok. I remember this same reaction when the frames with "plastic" grips came out! Quote Link to comment Share on other sites More sharing options...
Stage 3 Posted March 18 Share Posted March 18 Colt experimented with this in back in 1939 and brazed the halves together but it was never adopted for production. Electron Beam welding is a far superior method of joining the halves, I don't see any downside to this manufacturing method. Quote Link to comment Share on other sites More sharing options...
ltdmstr Posted March 18 Share Posted March 18 The downside is that it's still two pieces, and there are mating surfaces that aren't fused together via welding. That makes for a significantly weaker part. Also, there's zero issues with machining when it comes to conventional/one piece receivers. So, despite their claims, in no way is this comparable, let alone superior. Quote Link to comment Share on other sites More sharing options...
perttime Posted March 20 Share Posted March 20 As far as I understand, electron Beam welding can penetrate quite deep into a seam, so the surfaces can be completely fused. Quote Link to comment Share on other sites More sharing options...
Stage 3 Posted March 20 Share Posted March 20 We used EB Welding for manufacturing jet/turbine engine parts, and two metals can be completely joined together. Not saying that this is a superior method of manufacturing 1911 frames, I just don't see a downside to it. Quote Link to comment Share on other sites More sharing options...
Zachjet Posted March 20 Share Posted March 20 The real question is what’s wrong with the standard way of making 1911 frames that it needs to be done differently Quote Link to comment Share on other sites More sharing options...

I assumed not, but could be wrong. If they are doing full penetration welds, does a 1/4" or more deep laser weld not generate enough heat to cause distortion?

Electron Beam, not Laser: https://www.ebpglobal.com/electron-beam-welding-vs-laser-welding/ "It is widely recognised that EB welding is a low-distortion process, particularly for large structures. This is because the heat input of EB welding is localised in a narrow region and no filler material is involved." https://www.sciencedirect.com/science/article/pii/S0308016122001582 Quote Link to comment Share on other sites More sharing options...
Yeti Posted March 21 Share Posted March 21 Vudoo makes some very nice, accurate rifles. I'm inclined to believe with the QC they have in place that they will also make an excellent 1911. Electron beam welding is amazing...expensive, but amazing. I will probably just stick with the old school, low tech 1911's I currently have though.

Like I said, not sure how this approach is an improvement over traditional methods. Just because it's new or different doesn't mean it's better.

Life was great then! and before anyone posts a distracting red herring definition to distract from the actual issue, let's keep in mind that the luddite naysayers don't appear to actually know anything about the gun, and almost nothing about the technology. I don't either, so I'll wait and see instead of shooting off my mouth like mr know-it-all.

perttime Posted Thursday at 05:06 PM Share Posted Thursday at 05:06 PM What I meant was: the way things have been done before isn't necessarily superior just because it is the way things have been done before. These pistols ain't exactly cheap, so I doubt we'll soon hear many reports about 50,000 rounds being fired through one with no issues. Sadly, I'm not in position to buy one of these now, and 50,000 rounds of .45 ACP. Quote Link to comment Share on other sites More sharing options...
