I've always wanted to make one of these, but that feeling everything I make is garbage always kept me from doing it.
I print in my place - rented, there was a spare room with a closet. Closet turns into darkroom, which I originally setup with a friend to print film. I still have all the enlarging/printing equipment for photos but these days the room usually serves as a place to dry screens in the dark.
In the beginning I got into screen printing because it seemed like the best method to print stupid t-shirts people would spend money on. A talented individual came up with some four-color rotating printing press plans, so my former roommate and myself built the fucker. I rebuilt the rotating assembly a number of times, each time because I fucked something up the time before. It's been a lot of trouble, especially because I didn't know fuck-all about working with wood or anything like that before I started, but it's a cool machine. Currently have it tweaked out to hold register to within a 32nd of an inch on a good day, and modified to use a sliding platen and hold 23x31" frames. I don't print t-shirts much anymore but I still use the press for printing canvas, which works better wet-on-wet.
I will try to post pictures of the equipment I use and also some process shots of posters and other things I do - they might be useful for someone who doesn't have access to a studio and wants to print at home. In addition, you may now all be privy to me either going down like a Hindenburg, exploding and raining Ulano tech sheets and dulled squeegee blades from the sky, or perhaps making some money and paying my rent. High stakes!
Right now I'm a little tired so I will do that stuff later. Until then here are some pictures I drew in paint a long time ago. Please take note of the thematic consistency. I'm gonna go take pictures of the NATO shit tomorrow. Maybe I'll get beat up!
