So after all the advise from the good folks on this forum I decided not to a make a wood stand. I fabricated one from steel. I'm not a great welder/fabricator but even still this was a fun project. Turned out ok. Well ok so far, I've still got things to finish - flood coolant system and drain, elevated blocks so the mill doesn't sit directly on chip train, etc. I'm sure there are things I will wish I had designed into it but didn't. Hard to know what features to add before I get some time with the mill. Hopefully I can add it as it becomes apparent.
The base of the stand is made from 2.5" x 0.25" angle iron. After is was assembled I realized it might be overkill, but figured it was safer to error on the side of too heavy rather than too light. The chip tray was made second and I made it from 1" x .125" angle and 18 gauge sheet, metal. I wish I had gone heavier. Not only was the 18 gauge sheet metal hard to stick weld without blowing through it, but there is a tiny bit of flex in the tray that I would preferred not be there. Live and learn.
