The Home Machinist!

A friend of mine who does not have internet access is looking for a pair of "Allen 10-Wheeler" cylinder castings.
If you have or know of anybody who has a pair ageing under the workbench that won't be used and you want to sell please reply.
Thanks.
Andy

Of course new castings can be obtained from Allen Models.
My friend is looking for aged castings.

Andy:
Thanks for not being swayed by the wise guys and those who can't read.
You will be doing your friend and me a service. I have one unmachined Allen Ten Wheeler Casting I will sell for 1/2 of current new cost. If you or he are interested, please PM me. I have some other Ten Wheeler stuff if he has needs please include that in the pm and we can work something out. He can pay the shipping on USPS flate rate, so the more we can stuff in a box the better for us both. Of course, it dosen't matter where as long as the shipping is to a US state...cost is the same.

Aging castings is not necessary that was the old days and yes I can read Just trying to show support for suppliers, But it is typical live steamer s looking for a bargain. I apologize to the forum for the attitude but I'm a supplier also.

The age of castings does have a relevance, although how critical the aging would be for a cylinder leaves questions. Is it necessary? Perhaps. Perhaps not. It is unlikely a cylinder would undergo significant changes in features, although for a D valve engine, it is possible that the valve seat could change enough to create issues.

Castings have internal stresses that must be relieved before they become stable. That can be accomplished by rough machining, then allowing the item(s) to sit for a prolonged period of time. They can also be stress relieved in a furnace, or simply allowed to age without any machining (a slow process). Rough machining tends to remove unwanted material, allowing equalization of stresses to occur faster.

All what you are saying is true but I think in our line of work it is not critical. I have machined quit a number of cylinder castings over the years and found that is is more important to let them cool down before the final cut Iron expands and can shrink below the measured dimension.
Most armature machinist over look this point and maybe arn't even aware of it.

I have finally refined my skills to be able to measure the heat expansion on parts.

Regardless, the OP is looking for 'new old stock'... not new stock. Not much to debate. Let him look for them

I have an Allen blast pipe and nozzle along with some dome castings if anyone needs them.
