Redneck Canuck builds a steel cnc router

[John540i]

I am a design as I go type of guy so I don't have any CAD drawings for everybody to review before I start my build. I have looked at a number of the build logs and have based my design on aspects of those that I liked.

I have included some pictures of my shop so that you can see what sort of tools I am using to do this build. I will say that just because I own a milling machine it does not make me a machinist.

The frame is made out of steel because it is relatively cheap and I have the equipment to do it. The legs bolt onto the main table so that it can be moved. All of the welding and steel work is going to be done in my garage but once I have a rolling chassis it will be moved into my basement.

All of the axis run on round linear rails. The x axis has two ball screws and the y and z each have one.

The main part of the table and legs are done and I am now starting for on the gantry. The table is a bit high. The legs are 36” and I find that to be a good height for a working surface but with the thickness of the table and the adjustable feet the table is closer to 40” I am going to leave this for now and if I find it to high to work on I can cut the legs down.
