I need to replace the dome on a Darley siren. The main body diameter (just above the vertical slots) is 20 3/8". Any thoughts on something close? Willing to pay for a usable whatever. A 20" something would let me hand form the bottom to match. I've been measuring everything I come across. Thanks everyone Keith
Thought about that but haven't seen anything yet that would look nice. Looked at purchasing a tank end pressing but didn't get much help, not a OEM so even if they have one..... Also thought about hydro forming one but don't know what size circles to start with. That and the risks associated. Willing to pay a fair price for something. Hopefully someone will measure up their junk and sell me something.
I hate to say it but that in all honesty is the first thing that popped into my mind. Kids last week at school just used an IKEA salad bowl for a dome on their model Van DeGraff accelerator. Into sirens " Screwloose " , that is an interesting hobby for sure. Saw some pictures and posts a while back but had forgotten about that. If I think of anything I will pass it on.
If it works it works. It’s not so bad lately but we had to get real crafty for a bit with the major parts shortages.
Do you know of any local machine shops that do metal spinning? I'm not sure what the cost would be for a one-off piece, but maybe not too bad? Like this place: Metal Spinning Services - High Volume Spun Metal - Spin Forming | Wenzel Metal Spinning
Can you roll a cylinder that is tapered ( like a coffee cup shape) and then use something smaller diameter on top. End of a propane tank that might be smaller? Giant funnel with a cap on the end. Just thinkin.
This has become a problem again for us trying to get parts for the racing side of things. It was really bad , then pretty good and now it seems every day that passes things harder to get = AGAIN.
I looked a bit and it is really a volume requirement type of job. Have to make the form and the cost of that for 1 piece doesn't work.
So I have spent a half hour looking at stainless bowls! I'm thinking if I can find a round bottom 30 quart I'd be set. Thanks for the ideas!! Should have posted this sooner.
You'd need to measure. flip it over Bayou Classic Aluminum Grill Stockpot with Basket 34 qt 14 L X 13.88 in. W 1 pk - Ace Hardware
Is there a restaurant supply store close? Might be fun to see their reaction when you tell them what it’s for!
