67 x 37 ? 67x37=2479 sq inches ?
rough dimensions of the part is 4 x 6, qty 12 4x6x12 = 288 sq inches
did you mean 67 x 3.7 ?
Yes. Missed the decimal. Or 37" x 6"

I see needing about 36"x8" piece of steel to cut these.
With a which is about 2 sqft of material, at about 15.4lbs for 3/16 material.
I pay about .50lbs for steel so the steel would cost about $8.50 with tax, shipping would be roughly 6-10 bucks with flat rate boxes, which I believe these all would fit in one box.
I know you need to make a profit, but my math is not aligning with yours what am I missing.
Where are you buying Stainless at $0.50 per pound? I want in on that.

The original post just said steel, I also the person I quoted indicated A36 steel.
If you're going the hole saw route, you definitely need (as other's have said) a better drill press than the off-the-shelf stuff from a big-box store.
I have a 17" Delta that would do the work - and if you're similarly equipped, here are the things you need to consider.
1) The table must be near to exactly perpendicular to the centerline of the chuck. You want the hole saw to make even contact all the way around the cutting arc. A little off to the left, right, front or back will cause the hole saw to grab and that will most likely snap off the pilot drill.
2) Put the table up as high as you can in relation to the cutter. Less extension on the quill will make the drill press more stable.
3) Run it as slow as you can, and leave the belt a little bit loose, so when the hole saw grabs (and it will), the belt will slip and lessen the torque shock to the setup.
4) Clamp the part to the table 6 ways from sunday. You do not want it to move even a little bit.
5) Use a cutting fluid of some sort. I've got some really nasty sulpherous (sp?) oil that I use when threading water pipe - that works well. You want something that won't boil off with heat.
I used the above techniques to cut arcs out of a piece of 3" x 1/4" wall square tube. Only broke one piloting bit.
It took three days less than forever...
I see some actual businesses are jumping in on this. I'm not a business. I'm just a retired Tool & Die Maker that has some equipment that likes to help people out where they don't have to pay a large amount for something simple. I may not be the quickest with a manual mill or my CNC mill as some others are, but I do turn out a top notch piece. Just like me, others out there don't have deep pockets either. Those are the ones I like to help out, and maybe someday they can help me out also.
Kind of funny I think I did the OP a favor...all the hero's (I say this in jest) are under bidding me...
Dang I had it in my head it was Stainless...
Revised numbers:
12 pcs @ 15.24 each
1000 pcs @ 3.57 each
Now I am heading down to the shop to build a CraniumfromSphincter removal tool so I can get my head out...
it's nice to see so many guys step up and offer their services. How many other forums out there are you going to find that ?
Hats off to all you guys.

I am making this post mandatory reading for my adult Ed blueprint reading class. We will have fun looking up all the various processes you all have referenced on YouTube
Thanks for the suggestion badidea. Im not the best at cutting arcs with a grinder. The problem is I need to make 12 of them. Thanks Kevin, the only problem is i need a bunch of them, and would like to be able to make more. I do not have an acetylene torch or plasma cutter, or mill. Is a big *** hole saw out of the question?
One last question, can a hole saw be used to say cut with say 25 percent of the circle? What i mean is do I need to support the rest of the blade that is not in contact with the steel. I figured if it is not in contact, it would create lateral force on the quill, possibly straining the internal bearings. Am I correct? This forum is awesome. Thank you all
"One last question, can a hole saw be used to say cut with say 25 percent of the circle?"
Im going to disagree with Larry here. I don't see a problem, in fact it will take less torque to drive the saw. Being a woodworker your used to making quick fixtures right. Stop off the back/opposite corner so you can flip them with one fixture, and holesaw the corner off. Pilot the saw into your fixture with the drill bit. The stop can just be some ply or hardwood strips tacked down. Do it man!
Holesaws are used a LOT off center to notch tubing... with no pilot drill...

They are on the house...had some other things I need for the shop at home. So why not run them with my stuff.
Hope you don't mind they are .179 thk. I had a whole pile of 24 x 30 blanks of that.

That's really nice of you 4 FN 27.
However... I didn't see anyone ask OP what he was doing with the brackets? What if these are the final pieces of his slant drilling water supply poisoning machine or some sort of attack dirigible?![]()
