4 layer screen printing press, Revisit

I  got around to modifying my printing press that was built a year ago. Upon first print I discovered a few minor flaws in my design. I Stuck with the same over all concept, Keeping the castors, I added 1x2's to the exterior for a little more support

Replacing the inaccurate 2x4 arms with  2x2 aluminum tubing ,that was cut to the 1000 of an inch at a machine shop is a more light weight and extremely accurate  alternative.  finding a square chunk of steel for the top of the base, helped prevent the Eye hooks from rotating when the arms were pressed down. Also Moving the location of the springs from the side of the arm to the brace of the screen increased the tension,  preventing the screens from flopping down when rotated.

Four Sets of wheels guide the arm into place, giving it an  accuracy withing 1/100th of an inch.. Last but not least, I added a coat of black paint, to make it look classy as fuck. Over all cost was around 70 bucks, Sure does beat the price of around a grand for something mass produced.
