Richard Schultz Petal Table, broken petal  

Doesn't seem like such a...
Doesn't seem like such a small job when you consider:
1 it is aluminum, which is a lot harder to weld than steel, and prone to things like warping and getting blowing holes through it.
2 the paint will need to removed from around the break
3 the weld will need to be ground and polished smooth
If I were you I wold mark and remove the petals before sending it out so they don't get banged around. And make sure you explain this piece has significant value.

Thanks, Leif! I found some...
Thanks, Leif! I found some local welding shops and think I will start there... if I'm not comfy with the shops I will continue to search.

My god lainey
please keep us posted as to your repair. What an awful injury to have had happen to your lovely petal. I would have needed a swig directly out of the bottle had it been me.
Best of luck,
Aunt Mark

Just make sure they understan...
Just make sure they understand this is a very nice piece of furniture and then end result needs to be ground and polished just as smooth as the other arms on the table. So that you can get it repainted and it will be back to as good as new. If they have the capacity to repainted it you might get them to do it.
Also make sure they understand the leaves go on those arms and any warping is going to make the leaf not sit in the right plane, and that would be a big problem.
Perhaps an auto body shop would be able to handle it. They would understand that it needs to come out looking new, as that is what their business is.

well
the original is cast, right? and edges roughly ground. I had one and that is what I remember. Not that pretty to begin with...gives them a little wiggle room

Great! Wiggle room is good....
Great! Wiggle room is good. (I've never seen one in person). But I have seen what a welder does when you hand over two pieces of metal to be stuck together without further instruction. And it ain't pretty.

absolutely
agree...
try not to f* it up. Are those instructions?

Those are suggestions.
"DON'T f* it up" is an instruction.
And by the way... If anyone here is looking for a guaranteed successful business: Open a machine shop and make on-time delivery your #1 priority. If you can do work on-schedule, it almost won't matter what you charge.
Be aware, though, that to do this you'll have to find and hire metal workers who don't smoke a ton of weed... So staffing your shop will at best take a very long time, and at worst might be impossible.

repairing the Richard Schultz Pedal Table
I have welded as a profession since 1981. You guys are rough on welders.
The Pedal table is cast aluminum. All cast is more difficult to weld than typical mild steel since it is porous.
First find a welder that can weld Cast aluminum. Call Around.
Second. Get a piece of scrap 3/4 plywood, unscrew the pedals and screw the plywood onto the base. Fasten the broken piece Exactly where you want it. This will keep the guess work out of the equation and keep the other pedals from getting burned or otherwise damaged.
Any welder worth his/her salt will know how properly prepare the joint to weld.
It cant hurt to mention you want it to look original after being repaired, but don't tell the welder how to do their job.
Aluminum takes a lot of heat to weld so the finish will be damaged.
Take it to a powder coating facility if you want it perfect.
Welders typically know of a few.
And yes I would risk being charged more and tell all parties the value before dropping it off.

You guys are too funny!
Thanks for all the kind messages of support... and etc! hahahaha
Here's a little, blurry picture showing the broken petal and where it's supposed to go on the piece:

I definitely am feeling the instruction: don't f' it up!
It's why I decided to seek all of your opinions really.
The story with this piece is that my brother was given it from Richard Schultz company as a donation to his charity, JDRF, which he was heading a silent auction one year.
Something happened in transit to the piece. I don't know how exactly it came to be broken. My brother has never disclosed it, but needless to say, it wasn't able to be put into the auction. He used it as a broken side table for his office phone for many years and I've since abducted it for my own personal use. I adore its history and mid-century modern beauty. It's a cool piece that actually has been getting a lot of use in my original 1968 Airstream Ambassador, named the Silver Whale, which I call home!
HawaiiModern, are you a welder on one of the islands? I know a guy with an Airstream there who needs some work done! Thank you for all your great advice.
RE: the plywood idea, would you're saying, not to cut the plywood into the petal pieces, just take a round piece of 3/4" plywood and screw it in to the entire base? Is that to keep the welded piece "honest" with the others? I don't really have access to a lot of tools, so unless someone at like Lowe's or Home Depot can do that for me... it's going to be a little tough.
You guys are great, thanks again!

One piece of plywood
And it does not even need to be round. I am suggesting this to keep everything in place. Maybe bring it in to the shop and let the welder fasten it to the base. My original thought was/is that if you did it, you would get the broken arm exactly where you want and protect the others from heat and damage from us surly welders.
Yes, I am on Oahu, I am retired here though. Guess I was one who didn't smoke the weed and ran an efficient shop with "on-time delivery your #1 priority".
Haha . I am going to go out on a limb and say thats good advice for all business.

Welders
Another place to seek a good welder is a motorcycle repair shop--they deal with cast aluminum all the time and their pieces have to fit perfectly as well as look good too.
