Step 2: The X Stage Rails and Motor

Next its time to add the rails for the X axis stage. These rails are 3/4 inch U chanel aluminum that you can get from the hardware store. Put a washer under each end to space the rail off the pipe just a bit. Don't worry about the rails being perfectly parallel. You'll see why later. Now mount the stepper motor with a bracket like you see here. Connect a length of 1/4 by 20 threaded rod to the motor shaft with a short piece of rubber hose (1/4 inch fuel line). Now your ready to set the movable part of the X axis(the stage).

Could i use other types of pipe such as pvc as they are a lot easier to drill through?

Hey, can someone tell me how to remove the old gears that are that are on the end of the stepper motors that i pulled out the old dot matrix printers? They seem harder then plastic, can't seem to pull them off, i might be being to cuatios and trying not to damage the motors. Not sure if i need to cut them off or what.
Tom

I found my stepper motors in an old inkjet and scanner. When i yanked iut what i needed an d scavenged the rest of the coolbits i was left with two motseith two connectiins each. Any ideaswhat i can use these guys for? I haven't done a lot of work with little motors, and am a blank slate of creativity here.

Hi Tom! I`d like to ask you for the long of threaded rod to the motor shaft.If I want to make some square base what would be the size of this square?. Thanks

does the far end of the threaded rod (left, on picture) just hang/sit/rub on the steel pipe? Should/can you support it somehow?

I found it easier to just take a few minutes and grind a section out of the pipe that way the coupling nut could travel past the piping for an extensive use of the X axis.  I also welded a sleeve into the slot where I extraced material on the piping, and not necessarily for structural reasons, but for a nicer look(sucks to be OCD). 
could I see a photo of that please

Tom you did not mention anything about the motor specifications ... what kind should i get ?

The threaded rod will attach to the moving platforms, that'll secure them just fine at the other end.
Ok i'm a little clueless, but what did you use to drill/tap the holes, so that you could screw the rails into the pipe?? Thanx.

What kind of rubber hose did you use? I'm still searching for it.
