Naturally, this means that I must come up with a way to mount the one on the other – my 10-year-old would curse [...] We have a friend in full-scale firearms manufacturing who was looking at making a large run of 1911 pistols. In order to reduce his machining costs, he bought a sample batch of frame and slide castings from Coast Metal Casting – and they turned out to be next to worthless. So we borrowed a set [...] Today we’re taking a look at what is required to use a modern CNC machining center to reproduce a part designed for factory production on a bank of horizontal milling machines. It’s not as trivial as many people think – CNC has some definite limitations. The part is from an RP46 top cover, a conversion [...] I’ve been working on the lathe for a couple days at school, and been doing turning and drilling (no threading yet). I finished the sample piece my instructor wanted (a cylinder with several different diameters and grooves, which we will be using for threading instruction tomorrow), and I was looking for something to practice these [...] |
