« Part 2: X-Axis Part 3 of 3D Router series no next part

Work on the gantry and Y axis rails. All the bearings installed and mocked up the gantry to the table.

Mounted the rear stops for the Y-axis box.

This is the Y-axis box being assembled.

Threaded insert in the top of the Y-axis box so it can be lowered up and down on the gantry.

Cut and drilled the rails for the Y-axis

Installed using some ‘Old School slot screws”. I clocked all of them.

Mounting the Y-axis piece to the box.

These bottom holes on the gantry where the bottom bearing mounts were suppose to have a +/- 1 mm on the top side. But I ended up needing to have that clearance on the bottom side for mine.

Gantry installed. It rolls real smooth except for at the very back couple of inches. Will have to do some measuring and see what is off.

Finished putting the screws in the Y-axis front piece and realized the top board with the threaded insert I showed early was installed 180*. So I couldn’t mock it up. That was it for me so called it a day. When I start making mistakes it time to go in the house and wind down for the day.

Couple of close shots of the bearings. I came out with good tolerance on everything which I was worried about since the start. Can’t imagine how much trial and error the guy that designed this had unless he built it all on the computer.

Looking good, the only thing I noticed after watching the video that was lacking was a handle lock so that he can remove his hand.

Thanks Randy. Are you referring to the up and down action of the Z axis? If so I does have a stop adjustment.
