14" x 13 9/16" Cylinder 1/4" thick Steel

I need one of these, and I cant make it myself, so Im hoping somebody here can make me one, because that would be great
It needs to be 14" deep and 13 9/16ths" in diameter and 1/4" thick, perferred it to be steel. I dont really like coming here and this being my first post and all and commanding people to make it for me. However I do need this quite badly, Id be more than glad to pay for it, however much it costs.

I don't know how critical the dia. & wall thickness are, but unless there's steel pipe out there that matches, you won't like the cost of having a steel fab. co. make it.

Sorry, this is not the place to place an order for a cylinder.

This is something that is not easy to make and is why Mike's suggestion that it would be expensive is true.
The size you quoted is not a size I recognize as being a standard pipe size.
Even so, you would need to locate something that is pre-made in order for it to be reasonably priced.


What is this for?

It is for a drum mold. The inside diameter doesnt matter too much, as long as it wont bend easily, however the outside diameter has to be 13" 9/16ths or else the drum head will not fit on the drum. I am not too worried about the price as I will be using it alot. Each piece of wood is .7mm thick, and this mold if for a 8ply drum.

You will need to have this cylinder custom made.
The place to consult would be a welding/machine shop.
They might have some ideas for you.

Something else to consider would be having this made of wood.
Patterns in industry are often made of wood and maybe a pattern shop could fabricate something for you.

Let us know if you find a solution.

This is truly a one-of-a-kind device.

Idea one -
Begin with the next smaller size standard pipe with sufficient wall thickness to be turned down to the required o.d. in a lathe. If that does not work, then the pipe must be built up first, perhaps with some high-deposition welding rod, then turned down to the required diameter.

Idea two -
Build an oversize mold that can be cast in sand to produce the desired object. Create a cast bronze or brass version of the cylinder. Face off each end parallel to each other, drill a hole down the center, chuck into a lathe and turn down to desired diameter.

Good luck.

I was thinking about having made out of wood, but it would be much easier to use and store if it were made out of metal.

Make one out of cement.
roll a piece of sheet metal for the outside diameter, place a 1 gal paint can in the center if you don't want a solid core.
pour your cement.
you don't need to remove the sheet metal from the cement.

sheet metal 14" x 42.608"

13-9/16" = 13.562 x pie = 42.608"

Good idea GWIZ that is fairly simple to try.

The bottom could be placed in fine sand to contain the mix when poured.
If thin enough metal were used the seam may conform to the curve of the circumference.
The joint could be pop riveted with silicone between the seam layers to keep the joint from weeping.

We are really stretching our brain cells here osiris.
Have you contacted a machine shop to see what the real deal would cost and is this for a snare drum?

I have contacted a metal shop (in a way). My father owns one, he even said it would be hard to make. I might try that GWIZ, and I read your post before you edited it. Yes the wood is .7mm, its 1/42" thick. And the mold is for any shell that has 8plys, and yes, it would probably be maily used for snares.

I did a lot of prototype machining at one time.
What your asking is not that hard, Its awkward and time consuming, do to its size and weight.
Your item requires a larger machine then most shops may have.
I assume the closest size material would be 14" dia. with a 1" wall thickness.
They may want it about 4" longer for clamping, then saw 4" off.

If my weight calculator is accurate, a steel tube 18" long x 14" od x 1" wall will weigh 208 pounds.
the material would cost $100.00 to $200.00.
just to machine the outside diameter maybe $500.00 to $1000.00
If you want the inside machined you can double or triple that price.
getting it down to a 1/4" wall may present problems like chatter and ringing like a bell during machining.

Avoid having the inside machined if you can.

You stated 14" deep. if you need a bottom it would be best to weld a plate on the end of the tube.

Aluminum maybe a better choice.
It machines faster, that will lower the price of machining.
it weighs less, the price may come out the same as steel.
--------------------------------------------------------------
I would talk to sheet metal shops.
with a large slip roller they can roll a 1/4" sheet of steel, and weld the seam I would guess less then $250.0
------------------------------------------------------------
If you go with my first suggestion cement, you can try soldering the sheet metal together.
