200,000 psi closed Thread response

    Yes I fully understand that the people on this form have all of the schooling , degrees and knowledge that they have accumulated to accomplish all kinds of things.
    And buy my simple question, I did put on display my complete lack of knowledge in the things pertaining to my question. And you are absolutely right, I do have no idea what I'm doing.
    I am 56 years old, with just a high school education. I have a shop, a large drill press, and a mill lathe that I got from Harbor freight. I don't know a lot of things.
    But what I do know is that four years ago I had an idea. And last year I built my first working prototype.
    And by tossing aside all of the normal working parameters I have accomplished what many experts in the field have said could not be done, and I have broken records that have been established since the 1960s!

    I came to this form looking for honest help. And after making my first post, I was told to stop what I am doing immediately and seek out a professional engineer. I thought that's what I was doing by making the post on this form. I can see that what I stumbled across , was a bunch of people with high education but with no vision.

    Thank you for your time in responding to my question, you can now go back to your book and read about other people's accomplishments or you can answer someone else's post and try to discourage them also.
    As for me I'm going back out into the shop, and in a few months you will be reading about my accomplishments.

    Please accept our apologies. I think that SteamKing may have misinterpreted what you were asking. There was a concern for your safety in such a high pressure operation.

    If I understand correctly what you are asking is "what wall thickness should I use to be safe?" If you are willing (probably not), we can give it another shot. Any chance?

    Sure no problem, let me get some more information together so I can better explain what I'm trying to accomplish. Thank you I'll try to get back with you tomorrow.

    Google suggests using Lame's formulae?

    Hi Andersonaz1965,

    I'm sure you are aware of how dangerous what you are trying to do is. I have discussed your request with several staff members, and we are all in agreement on how to proceed. We could easily do some calculations on your system to develop a rough estimate of how thick to make the wall. And we could also make recommendations about how to design the part so as to avoid stress concentrations. But, in the end, we could not be sufficiently confident in the results to risk your safety on the outcome. Personally, if I had to design this part, I would do a first cut at the design, and then enlist the help of an expert to run a finite element stress analysis on the part. I would also depend on an expert to give me advice on how to fabricate the part and operate it safely. This is our recommendation to you. You really need to take every possible precaution so that your life is not at risk. I hope you understand.

    Chet
