    Nice! You wouldn't happen to have the solid works file for posting.

    By the way was the chair accurate to a tenth out of the EDM or did you have to lap it in? I ask because I've seen other videos for similar chairs and wonder how they went about getting the critical surfaces done.

    thank you for your reply
    I am attaching a link for all the solid works files (in Link)
    it was to one tenth before sandblasting (I did not have glass)
    off hand i don't remember a the accuracy but its way more then 1 tenth
    depending on the (E-pack) and number of passes
    a mirror finish is also possible
    let me know if the link does not work
