“Toolmaker's Chair” Do you know what it is ?

[shopandmath]

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
