Today: put together the supports for the x-axis lead screws. I will be using 1/4″-20 all thread (it’s cheap!).
I bought the cheapest 1/4″ ID bearings I could find. They have a 12mm diameter shoulder and 22mm outside diameter. That’s roughly 1/2″ and 7/8″, respectively. Since I’m drilling the holes in MDF, there’s naturally some inaccuracy involved. The small amount of slack will be quite welcome when the time comes to adjust the bearings’ position.
A while back, I also put together the slides for the y-axis linear bearing. Nothing exciting here, just a couple pieces of MDF and some aluminum angle.
