Glad  you started this Pottzy!  I will show my set up as soon as I get back into my shop. I think this great!  
I'll start....
I make about 200 pens a year.....about 4 of those segmented....I am now pouring most of my acrylic and 196 of those are acrylic...I have three lathes one of which is a metal lathe.....in case you are unaware metal lathes are awesome to do a bunch of things for pens on.   I have a 18/36 Lagaua for shaping the body, and I have a Rikon midi with a Beall buff permanently on it.   The pressure pot is a California Air.   I just got into casting just this year.  I built my own TS sled for segmenting.  My segmenting is mostly wood and then finished with glu boost.   I get most of my supplies from Exotic Blanks....they are awesome.  What about others what do you use and make?
