Machining looks great. As to ematal coating or alloy I can't tell you anything as I don't know what an alloy is and how I could tell the diffrence to a coating. Sorry for that!
Perhaps @nelsonm64 can.
Still haven't found the time to try it. Will have to wait until tomorrow. In the meantime I'm vaping on my new Goblin Clone that I got yesterday. Very nice and very good taste! Sort of hopped into my basket at foalecig, accident.......![]()
I hate those basket jumping accidents. More than one lone mod or atty has found its way to my mailbox.
