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:

Enjoy and I am looking forward to your comments.

Is this on an 80% lower like the Tannery Shops sells or a completely from scratch type deal?

Mike

PS - are you the Ray-Vin that designed the bore guide I got from GPSS, great cleaning tool IMO, "thanks" if you are.

How do we go about obtaining a copy of this book?

Ditto what Giffman said, How do I get one?

I would be interested in looking at your book and giving feedback. Let me know.
Link Posted: 2/5/2004 10:58:16 AM EDT
i would be interested in the book also.  i'm right in the middle of a o% right now.  it is my first.  i would be more than willing to give feed back on the book for you.

Absolutely fascinating.  I am not a machinist but I admire the art.  The photos, drawings and descriptions are fabulous.  Truly increased my appreciation of the finished product.

Thank you.

PS: Now I wonder why lowers don't cost $600 each?

That is amazing help and clarity, especially with a very good way to do the trigger well.

Ive been waiting for this and man and thank you for your time involved making this book.

I have been looking forward to spending my tax refund on worthy tasks and this will simplify getting it done.
Thanks for the info on this and I will let you know how it turns out.
Thanks

Thank you, for sharing your hard work with us my 80% lower just came in today so now its time for me to get that new milling machine. your information will now be my guide and is greatly appreciated.
Link Posted: 2/7/2004 5:18:13 PM EDT
Amazing!

I have only read about three pages of it soo far but all I can say is than you so much!

Its great to have people doing things like this!
Link Posted: 2/7/2004 5:32:40 PM EDT
SWEEEET!

Very nicely done.

'Tis gonna be printed, slapped in a binder, and take up residence next to my mini-mill!

Fan OTBR,
I love your statement about C and C++! Now add in windows api and and they will be lucky to find a big enough piece to do a DNA test...[beer]

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

Ray It would be great to look over what you've written...I am just getting ready to start my 0% forged within the next month and have been compiling info on it.  Thanks  

Link Posted: 2/11/2004 9:50:50 PM EDT
I am intrigued. I have done many cast lowers but never wanted to mess with attempting to fixture for the forged blanks. I would very much like to see your view of the process.

I could use the link. Does it also cover the .308 lower?
Thanks,

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,

Link Posted: 2/12/2004 9:19:07 PM EDT
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.  
Link Posted: 2/13/2004 2:44:16 AM EDT
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

With all these folks asking for the link, why not just post it up here?
Link Posted: 2/13/2004 9:04:10 AM EDT
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

Good plan.  [: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]

I too, would like a look at your work. I have made many lowers out of forgings here at home. I would like to think I could give you some helpful feedback (but i doubt it)  thanks

FanOfTBR,
I found that missing extension and fixed a day or two ago. Glad you like and thank you for the compliments.
I am sure when people actually get to cutting metal I will get some solid feedback on areas that might be clearer.
