Phase Three: Y-Axis

HOME

The Y-axis begins to take shape

 

The trick here is that the x-axis mounts have to be perfectly square to the y-axis mounts. Since it is difficult to make a perfectly square cut in the 1/2" aluminum plate, I found two pieces of CNC cut aluminum that were perfectly square and used these for the side plates of the x-axis. Of course this was before I found out that you can cut the aluminum plate with a power miter saw and a carbide tipped blade.

 

Laying out the side plates so the shafts are perfectly parallel takes a fair amount of time, but it is well worth the effort. The x-axis slides just as smoothly as the y-axis and there is no binding.

 

You can see that this is turning into quite the machine. I originally was shooting for 8x10" of travel, but I scaled it up a bit and now have about 11x16".

 

I got the motor plates all drilled and ready for the lead screw this weekend. I had to take my time because I wanted things to line up perfectly.

 

Here you can see the ab-nut that I made. I still have to make the mounting bracket that connects the nut to the axis.
