Hi all! I have been threatening to do this book on how to machine the AR lower forging and I have been working on it (on & off) for almost two years now. Other demands prevent me from spending the time I would like on it so after several revisions, I am offering it as is for free with no warrantee expressed or implied. All I ask is for some feed-back so I can improve it and eventually offer a print version at a nominal fee. Regards, Ray PS: OK, I have made my goal of haveing at least one Hot Topic here in my lifetime. No need to reply to this post anymore, here is the link: users.wfeca.net/rbrandes/ray-vin/ Enjoy and I am looking forward to your comments. |

Ray, Thanks for the additional information. I've tried a O% casting with poor results. Your clamping jigs should improve my chances. My first attempt came out of the vise and got ate. The casting was toast but usable so I practiced opening the mag well for the fun of it. Interesting paper weight for my desk. Because of your post, looks like I'll be giving it another try. You've done a great job on the book. It will help many get a 0% to that magical 100% mark. Thanks again, Terry |

I've been reading and looking at sites on building 100% to 80% lowers. I would be glad to read your book and give you some feed back. I had to finaly go to the get a lower, a upper, now I need the bolt group and barrel. But one of these day I want to mill my own. Best Of Luck, LSURVEYOR |
| Ray, I have been giving it a look over and must say you did a realy realy realy great job ! I can't wait to pick up my new mill in the morring. Next thing will be a DRO. and then a air conditioner for the shop ( those spring heat waves are just around the corner here in south AL ) But honestly the only thing that I think could help would be the tool speeds that you used per operation. I think by adding this little bit of info would be the icing on the cake. And could very well make your book a one stop guide. |

LG308, Where are you in South AL? We are in LA (Lower Alabama) ourselves, Marianna, FL. Speeds and feeds are an elusive beast. With manual machines, speeds are set and feeds are regulated by feel. In CNC, you set it all and cross your fingers when you hit the little green button! Here is a link to a speed & feed caculator: [url]http://www.emastercam.com/tools/utils/feedspeed/[/url] If I published speeds and feeds to use, someone would break or burn up a cutter and blame me. Better to figure some things out for yourself. However, since many first-time machinests are getting into this, I will consider your suggestion and put in some basic guidelines. Thanks for your compliments and feed-back. Regards, Ray |

Bill, I did post it, but what happens is that everyone (over 400 in the first few hours) downloads it and then the post slowly moves back to page six and then off the board. My plan is to get as many replys as possible and keep this topic at the top of the first page! [beer] Call me a glory hound if you must, but that is what I am doing for now. I may get tired of and stop (cuts into my drinking time). Right now I am having fun. Now, did you want the link? Regards, Ray |

[:D] Minor nitpick though....when you DID have things posted, one of the files didn't end with .pdf (I *think* it was chapter 13). No big deal, simple enough to add on myself, but I figured I'd point it out to ya. Overall the book seems VERY well done -- one of the best guides I've seen so far....wait....I think its the only real guide I've seen. Well, there's a couple "I took pics while machining stuff" type guides out there, but nothing close to a how-to. Good Job, and THANKS! [beer] edited to fix the [beer] |
