I need a large 304 stainless steel washer, with the following dimensions.

OD 21.5", ID 14.625" Thickness .5". Preferably flame cut, because laser
cutting is a great deal more expensive. So much so that it might get too
expensive for my needs.

Can anyone give me a price quote, or where I should go for this in the San
Francisco Bay Area.

Thanks in advance.

Sounds like an easy job for any shop that has a plasma cutter, CNC or
manual with a circle jig. Plasma is much cheaper than laser and produces
a much better cut than oxy/acet aka flame cut.

you cannot cut stainless with an oxy/acetelyne flame,
must use plasma or laser.

Or water jet.

I could to that easily. Half inch is on my edge though. Best to find some CNC guy with a 1260 Hypertherm
or such - I am told I can cut 1/2 and messy cut higher.

How perfect are the edges ? - is it a surface flat or is it show stuff.

I could cut and let you clean the edges as needed. Grinding or hammer/flat steel edge rod... :-)

It will have to be plasma or laser cut. You can't
flame cut stainless steel.

I meant to say "plasma cut" instead of "flame cut", my bad.

As far as the responses I have received are concerned, with all do respect, I
don't care how it's done.

What I need is a price quote or the name and phone number of a place in the San
Francisco Bay Area that can do this for me. I have not been able to find any
leads yet.

Thanks in advance.

Try these guys -- their brochure says they offer both abrasive
water-jet and plasma cutting in the size range you need, for nickel
alloys and stainless steel. They apparently have a San Francisco
office.

I am making a decorative "ceiling flange", to bridge the gap, between a new
stainless steel fireplace flue and the edge of the hole in the wooden ceiling
through which this flue passes.

Here is a before picture. http://www.abrasha.com/misc/ceiling%20gap.htm

Please note, that this is the old flue. It has terra cotta inside of galvanized
steel.

The new flue will be a galvanized steel flue, inside a 14 ga stainless steel
sleeve around which this ceiling flange will be installed. The new flue will
have a smaller diameter than the old one, so the gap in the photo will be wider.

Good grief! If that's what it's for why on earth do you need .5" thick
SS? Surely something in a much lighter gauge would be just fine. I'm big
on overkill, but even I wouldn't go that overboard.

Pete C.


I knew someone was going to mention that. I know I could get this in 14 ga or
10 ga and be done with it. However, 1/2" will look a great deal better. A thin
one will just look wimpy, and a thicker one will look just right. It's all
about aesthetics, not just function. I will post a picture when it's done.

I know the plate will weigh about 25 lbs, so it will be hollowed out from the
back, to reduce the weight to about 10 lbs, which will help a great deal during
installation.

So why don't I have the whole thing fabricated out of thinner stainless steel
sheet? Cost. The fabrication of such a plate, i.e. a 14 ga sheet welded onto
14 ga ring and cleaned up, and then drilled with a 6 hole bolt circle will cost
about 5 times as much as a machined 1/2" stainless steel washer.

I have quotes for that already. I am now just trying to get the raw material as
cheaply as possible. I already have the machinist lined up who will face both
sides of the plate, which will most likely be warped from the heat of plasma
cutting, trim the OD and ID to spec and hollow out the back and drill and
countersink the holes for the screws.

It will, of course, have your signature inlaid gold ring and rivets...?

Even if you forego the ring, I don't see how you could possibly resist
a nice triangular arrangement of gold rivets. Probably need, what,
about 1" thick rod to keep them in scale?

Seriously, it might make sense to just forget machining the back and
save the bucks, other than drilling the mounting holes -- the
difference in weight isn't going to make all that much difference,
given you will need to fasten it to the framing in any case. And if
you get it water-jet cut, there won't be any distortion. I'm not sure
what is cheaper with that size stock, plasma or water-jet, but not
machining it might make up the difference in any case. Might not
distort even with a plasma cutter -- you see that fancy scroll-work CNC
cut stuff all the time, and it doesn't warp, although of course it's
much thinner than 1/2 inch stock.

Have you considered making it something other than round? Hexagon or
octagon where it could be bent from lighter gauge sheet and only have a
few seams to weld vs. an entire perimeter?

Do you have any sort of tech schools in the area? Perhaps it could be
fab'd as a class project as low cost (either design).

Most good steel supply companys have a plasma burning table to cut
shapes. The cost of cutting at the supplyer I deal with is next to
nothing , probably 5 bucks for cutting the plate you need.

John

Now Pete put up another one - a 7 sided or 9 or - maybe an eyebrow shape on one side
or both long sides :-)

CAD is wonderful like that - did a foot ball looking C with T A&M within the T bridging
and below the A&M - the ampersand within the T.

I do ovals by doing a minor circle and then changing the height - a tall oval. Rotate as needed.

Been doing CAD for so many years in IC's and PCB - now to plasma cut the various metals.

Waterjet will give you an extremely nice cut. You can do the washer,
and any holes you need drilled all in one operation. There will be
absolutely no distortion, and the edge will have a nice sand-blasted
finish. It will probably be more expensive than plasma, though.

There are zillions of waterjet shops around. For a list of some of
them, visit:

I cut some 14 ga 304L today - nice cut. Used 40 amps and there was a little
whisker on the bottom and the normal brown line where it went through the extreme
temps.

It is likely doable with a large enough plasma cutter. Use fine cut (current density!)
the small beam carries all of the current. I had spray 3' long under it - but no
real problem. Nominal edge work is needed - the edge itself is black. Oxide I suppose.
So water jet isn't mandatory - but is a good choice.

Water jet does give some swarf on the edge - not as perfect as most think.
Normally they use man made semi-precious stone - garnet... spinel...

Martin - wish I had one and the building it takes to house.

Easy on a plasma table.

I'd think design needs to think on this - perhaps a unique shape - like a diamond
in the sky - when someone looks at it - they smile not just see something 'functional'
and assume it was someones standard part.

Something like a fan blade with lobes would be interesting -
