This project has legs.
The bearings have been inserted into two 3/4″ pieces of birch about 8″ long. Between the two boards is a 2′ long piece of threaded rod, in the middle of which is another board with a bolt glued into it and another threaded rod. The black rubber tube on the end is for the shaft of the Y-axis stepper motor. The opposite end of that rod still needs to be fastened to the bottom of the platten to hold it up.
However, I am having some second thoughts on the design. As it is, it doesn’t seem to work very well when the Y-axis rod is in the middle. I’ll know more once I have it installed, but having the motor on the right or left side might work better.
The bearings don’t slide too easily. I can tell they might need some silicone, teflon, grease, or something.
In the next post I’ll show you my Y-axis motor bracket and possibly the synthesizer I just finished.
By the way, sorry about that sideways pic, but I don’t really feel like fixing it.
