Finishing building the Y-Axis

Thanks to a friend of mine, I was able to get the M2.5 screws required to fix the motor. Thus, I made a small bracket which held the motor. This was then fixed to the Y-axis using some counter sunk screws such to not block the motor position. Once this was done, tensioning the belt was then possible. The extendable portion of the Y was simply held tight whilst a hole on each side was drilled. This was then screwed so if ever the belt wasn't fully tensioned, another hole could be drilled to adjust. 

The second part that was completed was the attachment of the ball bearing runner wheels. Like the Z runners, these proved to be an issue as both sides had to be kept level, particularly as the gap from both sides was quite far. The runners like the Z were bolted using 8M screws and nuts. On the motor side this was bolted to a separate bracket however on the extension side, it could be simply bolted to the side. One other issue was that the brackets had to be dissembled to allow me to drill the holes accurately with the vertical drill. Finally, one thing I noticed was the nuts loosened up over time with the friction of the runners. Hence, thread locking glue (loctite) was let to seep through the thread. Now the runners are secure on both the Z and Y. The image below shows the progress so far.
