    the problem I see here is after what has been put on here, you actually might be afraid of cutting it now, due to a few comments..
    Trust me, it won't machine itself.. give it a try.. might be easy. .
    Did you see the other thread about "What holds you back?" I gotta spend a few hours with a shovel and find the bench in the shop first...

    However, after seeing all the warnings about needing sharp tools lest it work harden, I ordered a few new end mills in various flavors. They will be here next week, so that gives me all weekend to procrastinate about cleaning the shop.

    Oops, my location isn't shown on this forum. Here is the Yew Ess Ay.. *Clicky on a users name to see their profile. Sorry but it's not sold in New hampsha.
    Only kidding, here's the hint but Ima gonna make you work for it. Copy paste the item description from his ebay link into your ebay search blank. You'll get a dozen sellers for it ranging from $10 and up. To the head you have to attach it to an arbor stud. Straight shank, R8, cat 30-40 etc.depending on what you have.

    954 aluminum bronze machines easily with hss or carbide tooling, beware the chips however.
    Fixture it up and machine at will, Whoever told you that it is a difficult material to machine is wrong. https://morganbronze.com/wp-content/...num_bronze.pdf

    I make these bearings from 954 often and have never had a tool failure, as mentioned be wary of the chips as they come off small, hot and sharp, I would recommend an enclosure and flood coolant for chip control.

    If it is to be a sword then it will have a pointy end so try a hacksaw to shape that bit. Blade is pretty cheap as a sacrificial try out.

    High positive rake inserts such as the type you would use for Aluminum would be the way to go, IMHO. For plain brass you can use HSS just fine with the edges blunted off so it doesn't grab.

    I was thinking the same thing.

    How do you know if tea is too hot to drink ?
    Sip it very slow and see.
    What else can be said unless you have access to a lab !?!!!

    How do you expect us to know ? ? ?

    It would be silly to ask you what it is.
    That is why I asked a different question -- "any suggestions as to how to get a better ID on the stuff?"
