I have started a small business recently call Rhomstyn Prototyping
(web page coming soon). I have one CNC milling machine and the
software to make solid model designs, drawings, and machine code for
input into my CNC mill. I also have engineering experience for those
of you who need design/modification analysis of your custom gun
parts. I am to bring you low prices in order for me to establish a
grounded reputation in the custom machining industry. Once
established, my hourly and project based prices WILL go up by 100%
or so. However, you can expect this not to happen for another 9-12
months. Take advantage of $20 per hour CNC machine rates, plus
material costs. You will not pay anything for programming or
tooling. You will not pay if the part does not meet your specs. My
introductory pricing is well below any CNC or even manual rate you
will probably ever see. As of Aug 29th 2005, expect approximately
one week turnaround. Keep in mind that my services are not limited
to machining, I can perform most any design and engineering tasks
you require. If you have special processing requirements for your
parts, I have shops that can presision weld, cast, turn, heat-treat,
and do many other custom processes. I can accept Iges, Parasolid,
Dwg, Pdf, Solidworks, and many other types of files or I can create
the necessary files from your part information for an additional $16
per hour. Part size is currently limited to 6"x5"x5". If you have good
idea but dont have the capability or budget to make it happen, send
a small project and try me out, Im sure you will be satisfied with the
quality, timeliness, and low cost of your project. Call me at
619-504-7206 or email at corbyh@texasshredder.com.

I would be quite interested in getting an 80% AR-15 forging that has the magazine well milled out for 9mm mags without the need to use a mag adapter... other guys here have done it jut not sold them....

Where in TX are you? I have a great idea for something that would probably sell like hotcakes. In the future I will need someone with CNC capabilities. Does your CNC machine have turning capabilities?

Im sure we could work something out. Do you have dimension specs or would this be something that would require me to have the parts in order to take measurements? If you can either draw something up, or send me the parts then I can take dimensions and make it for you. Just let me know and we'll try to work something out.

I am located just north of San Antonio. I dont currently have a 4th axis on my mill. Do you mean that you will need something turned on a lathe, or something that requires a 4h axis on a mill? Either way if the oppurtunity is good enough I can probably look into a small cnc lathe or rotary axis for my mill.

I guess I really need a CNC lathe to accomplish what I need. I have access to a fantastic lathe, but I don't look forward to making hundreds of these things.

Yeah, people usually charge a heck of a lot for a few cnc parts or they require you to buy a billion of them in order for you to get a decent price on one. However most things can be made on a mill, things that people think can only be made on a lathe. Lathes are really only good for long cylindrical objects and those that require perfect roundness for pivotal, rotational, or sealing functionality. If it is something not too long and more or less aesthetic in nature, chances are I could make it on a mill with a 4th axis. For example, all drill bits are made on a special grinding machine with typical mill-like axes setup and a 4th axis rotary. round stock is rotated slowly on this 4th axis will a grinding wheel comes down and travels linearly (in a straight line) along the round stocks length. A 4th axis is very useful for making things like flash suppressors and symetrical fore-stocks with various patterns.

Could you add material and then mill the end of an IMI Galil receiver to accept a Micro Galil folding stock?

Take the 9mm AR receiver idea... mill it to fit Glock mags... enjoy your new customer base as word of mouth spreads about how your selling 9mm AR lowers that take glock mags.

There are quite a few people who would like one of these but either don't want to buy it from Oly Arms because Oly will only sell them as a complete rifle and/or because it's made by Oly.

Produce a quality receiver that does this an I suspect you'll do well.

Yes, if you provide drawings or ship me the actual parts that need to be mated together.
Link Posted: 8/30/2005 11:19:09 AM EDT
Do you think you could lead me to drawings or to where I can purchase the components that need to be modified for this project? I would be happy to take on this one. Could you give me some more details?
Link Posted: 8/30/2005 11:22:40 AM EDT
I have nothing to give you... but maybe if you ask one of the gusy who owns one of the Oly Glock AR's if you could "borrow" it to do this and hook him up with one of your production receivers he might square you away.

If you had the receiver could you basically reverse engineer it and improve upon it?

Could you do something where you mill off the fence around the magazine release button but leave the plunger tube?

Why is that "fence" around the mag release an issue... just out of curiosity.
Link Posted: 8/30/2005 12:09:29 PM EDT
Yes, if I had the reciever I could quickly reverse engineer it and make improvements. That is my specialty. However, I dont want to go out looking for people to ask them if I can borrow their parts though. I would like a project were everything is more or less laid out and ready to go, as far as parts or drawings availability. If you can send me a reciever (or the part you need modified or improved) and a place to start making improvements we can get somewhere. Then I will send it back to you once I have produced a solid model with tolerances in my CAD package.
