Build a CNC Router from Scratch (Part 1): Complete Video Tutorial

Step 1: Linear Slide Bearings Video

The CNC router would be useless without a way to move the router on the axis without play. Linear slide bearings are the answer. They enable a very stable and smooth sliding motion without binding. this method of bearings has been used many times, so you can be sure they will work.

The slide bearings are one of the most important component to the CNC router, and it's good to get the concept down in the beginning. You will need about 6 of these in the CNC build at varying sizes (the gantry slide bearings will need to be much longer than the y and z axes.

You will need regular skate bearing (609zz), 5/16" nuts, 5/16" x 3/4" bolts, various drill bits and a 5/16" tap/drill bit set.

Metacafe rejected the purely instructional video for some reason. I ported these videos to youtube. Here is the link: http://www.youtube.com/watch?v=juvTRIwDcOI

Many thanks and my apologies for the inconvenience and my screaming children, Patrick
Oh thats ok, thank you for responding i'd probably prefer youtube anyway.

I cringed when I saw where your fingers were when you were using the hand drill with small drill bit. I have seen a bit break in the middle and the remaining bit in the drill go straight through a thumb. It was my thumb when I was a kid :S
