Oh, I have one, but it's only a little 1cm radius one, designed mainly

You might be interested in this site (sorry it's a Web site with
pictures and so on, some of it will probably be readable using Lynx, and
it's in French to boot, I'm sure it would interest you however):

He makes his own triode valves (or tubes, for those of us who speak the
other language known as English ;-) ) and in order to do that he has
designed and built among other things his own high vacuum pumps. I'm
sure you would be able to make one like his.
