Hi all,

I'm new here but thought I would post up a link to my vlog channel and progress on the CNC mill I have designed and began to build. I have just released part 5 of the series, where the column gets tack welded to the machine.

My intention is to update this thread every time I release a new part of the series so that you can all see the progress and hopefully provide some constructive criticism along the way.

My objective for this project is to design and build a CNC milling machine without the need for any machining of the parts. Ordinarily, building a mill requires a much bigger mill to get the axis surfaces flat and parallel.

By using aluminum tool plate (which is in theory pre-machined flat) and bolting the critical components rather than welding, it should be possible to avoid any machine work. After all, I'm building a mill because I don't have one!

Linear rails and ball screws are the cheap Chinese 20mm style that you can find on eBay etc.
