If there is anybody here that has experience pricing a sheet metal project I
would appreciate some ideas of what a commercial shop would charge for this.

I will be making a drip shield surrounding an 18"x30"x1" fixture plate using
304 SS in 20 gage. The shield will be at a 45 degrees angle all the way
around the plate up and away from the periphery. This shield will be about 7
inches tall and hence will add 14 inches to the overall width and length of
the plate. The attachment point will be a 1" horizontal flange with 1/4"
holes every 6 inches or so to screw it down to the plate surface. The
corners will have to be connected with screws and slots so that attachment
to a non perfect plate can still be accomplished. Hopefully I've described
it well enough that you can get a mental picture.

I have no experience in this at all and have no idea what to expect. I've
pretty much got the job unless I'm way out of line in the price department,
hence I need some ideas, don't have to be exact. I'm thinking in the $100
dollar range for labor plus material.

BTW I appreciate all the knowledge and help that this forum provides apart
from the political rhetoric.

You didn't say anything about the quantity you need.
If it is a one-off, you should probably budget $100-$200.
If you're going to get more than 5-10 made, a shop
can set up their cad machines to hammer it out for
a lot less, probably in the $20-$30 range.

Sorry, yes, this is a one-off.
So, my $100 plus materials sounds about right.
Thanks

Well... maybe. I'd suggest you avoid large state of the art CNC
sheetmetal shops. Setups are very expensive, and in general they don't
like to do a setup for one part that has no chance of going into
production. One shop I do some machining for now and then, has a $75
minimum to burn anything on the laser. Want a 3/4" square burned out of
1/8 SS, $75.

If you get quotes you find way out of line, ask if they know any smaller
shops that like to deal with little one-off jobs. Many big shops are
only too happy to send one-offs somewhere else.

No it won't. The length needed to rise 7 inches at a 45 degree angle is
9.898 inches (hypotenuse of a 45 degree triangle is sqrt(2) times the rise).
So the total amount added to the length and width of the sheet will be
twice that, or 19.796 inches. This is important to know if you're supplying
the material.

Also, if you want a rolled lip on the edge (good idea if you don't want
people to be cut on the sharp edge), you have to allow enough material
for that too. By eyeball, I'd say about half an inch for the rolled edge,
so add another inch to the overall length and width dimensions of the
sheet.

You are not understanding how I'm arriving at my figures. You are correct
that the hypotenuse means I would need more than 7 inches of material to
actually make it. But when looking at it the completed unit, since it rises
at a 45 degree angle, the over all length of the whole plate with applied
splash shield is 18" plus 7" plus 7" equals 22". Since it rises 7" that
means that it is going to overhang by 7 inches as well.

I understand that. What I was telling you is that the sheet you cut to
form the shield is going to have to be about 6 inches longer and wider
than that because of the geometry, and because you'll probably want
to roll a finished edge on the shield.

Sorry for the confusion.
