Initial design for my CNC mill\router based around C beams

If you're doing metal work, you're going to want to stiffen your Z axis from the get go and get a spindle, not a router (low RPM, high torque). Probably wider plates on your Y as well. The 2020 rails WILL flex from plunging so go 2040 at minimum or find use cast corners to bolt them to your table as close to the Y rails as possible.
The 2020 holding up the X axis is only a temporary setup. Ideally I will machine some aluminium plates to replace the XL plate running along the Y axis, along with the C beam endplates on the X axis C beam (similar to the OX).
Unfortunately a spindle is hard to come by - I can import one, but obviously the risk goes up as I dont know what I am getting, and the shipping cost can be huge. Even sending US$200 worth of parts to NZ costs US$70.
Most of the spindles are from china anyways. Just get one off ebay
And that's not much.... I paid 90$ US to get my 1 meter rails to Canada.....
The $70US is just for plates - if I was going to get the C beams shipped here, it would cost $200US for 1 1m C beam!
I will look into the spindle idea.
why not get them cut locally?
Small qty stuff is hard to get done around here. It would end up costing more than importing them.
weird. Here they charge by the hour, so it doesnt matter
