I am trying to find 4130 in my area, and am finding that a LOT .... scratch that, ALL of these metal fabrication supply houses around Memphis don't even know what 4130 is. Is on-line purchase the only way you guys have found what is needed? I want to make one out of plain stock instead of buying flats from Brownells or wherever just to say I did it. After all, this is supposed to be fun. I've got my CAD drawing printed out to scale, but what good is a CAD drawing if you can't get the material???
I'm betting Home Depot doesn't carry this stuff... Any ideas? |

I've ordered metal from this company with great results:

Yeah, I'm familiar with them, and I will use them if need be. I was just wanting to support my local businesses. But if my local businesses don't know what the heck I'm talking about.... Guess I got no choice. I was just hoping someone was going to come back with a "you idiot, don't you know you can pick some 4130 at the XYZ store???" Next question. Do I want "Annealed"? |

Okay. Thanks!
Next question... I want to make a 555th jig. Is there a way I'm not thinking of to "easily" cut 1/4" steel? I don't have a cutting torch or a CNC machine at my disposal. My workaround at this point in time is to cut 1/8" plate with cutoff wheel times 10 (2 welded together for the outer pieces times 2, 6 welded together for the center piece) |

Yes, not everyone has a band saw. I try to mention tools that most have or can buy for a little cash outlay.
Try to take a few pictures of your progress as you work. A lot of builders have never done a 0% build. It is the way it was done years ago when the hobby started because there wasn't any flats or 100% receivers to buy.

Yeah, I'm kinda geeked out about it! Just to be clear, I was talking about cutting 1/4" steel for the 555th jig, not the 1mm steel for the flat. You think 1/4" on a bandsaw is ok as long as I go super slow and use cutting oil? They make metal cutting band saws. We have one in our shop and it zips through 1/4" no problem. |

Look at a Milwaukee metal cutting circular saw.

I'm thinking a band saw gives me the best chance to cut an exact straight line. Holding the blade against stationary work is never as accurate as holding the work against a stationary blade. |
