Pancho07 Posted October 7, 2016 Share Posted October 7, 2016 Was wandering around YouTube and came across this video. probably old hat for some of you but I hadn't thought of it and thought others might find it interesting or useful.

Frosty Posted October 7, 2016 Share Posted October 7, 2016 That was well worth watching, thank you for the link Pancho. One word about using your drill press like a lathe, the bearings in the quill are not designed to take lateral pressure and will wear quickly if you push sideways on the chuck. Sooo if you use the technique to make patterns like in this video use a very light touch with the grinder. I'd sure be tempted to use 4140 for the spring die though, case hardening might prevent surface wear but it won't do anything to prevent deformation. Frosty The Lucky.

Pancho07 Posted October 7, 2016 Author Share Posted October 7, 2016 That about the bearings I learned when I was considering finishing an 80% ar lower or 3, which is why I never followed through with it. Quote Link to comment Share on other sites More sharing options...
Frosty Posted October 7, 2016 Share Posted October 7, 2016 I'm sorry Pancho, I don't understand your last post. Can you slow down typing or proof read them please? You've lost me. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
Pancho07 Posted October 7, 2016 Author Share Posted October 7, 2016 Sorry, I tend to lose a lot of people. Sometimes I think I speak a different English than most of the population. I was referring to your comment about the bearings in the quill. About a year ago I was looking into buying a couple 80% completed AR15 lower receivers. They can be shipped directly to your house with out an FFL transfer and are milled to 80%, give or take of the finished product. The end user has to mill out the last 10%, the cavity for the trigger mechanism and holes for the pins that keep the trigger in place and connect it to the upper receiver. This can be done with a drill press but most of the suppliers of the "80%s" tend to advise not doing this as, as you said, a drill press' chuck is not made to take lateral pressure. sorry for the confusion Quote Link to comment Share on other sites More sharing options...
Frosty Posted October 7, 2016 Share Posted October 7, 2016 No worries, confusion is the story of my life. Thanks for clarifying. Sometimes I just type what I'm thinking without thinking about it and lose myself if I read it later. Unfortunately or maybe fortunately the keyboard on this laptop doesn't register to the reflex typist brain node properly so I can't type at my old 75+wpm. If I get going now I make so many mistakes I might as well let the cat type. Frosty The Lucky. Quote Link to comment Share on other sites More sharing options...
SmoothBore Posted October 13, 2016 Share Posted October 13, 2016 A few years ago, I milled out a couple of those 80% lower receivers. I can't imagine the hacked-up mess you'd get, trying to do that job on a drill press. But hey, ... if someone posted it on the inter-web, ... then it's got to be correct.

Yep, and following some of them videos could cost you a finger or two, or worse. Quote Link to comment Share on other sites More sharing options...
Pancho07 Posted October 13, 2016 Author Share Posted October 13, 2016 That's another reason I didn't do it. With the proper equipment it would be pretty easy but I'd didn't have access to it. Quote Link to comment Share on other sites More sharing options...
Bad Creek Blacksmith Posted December 5, 2016 Share Posted December 5, 2016 Nice post once I get my power hammer done and time on my hands will have to make one of these, and if I fail guess I'll buy one. Quote Link to comment Share on other sites More sharing options...
