Tall Enclosed - I like it always being in compression for the full height and that the full width would provide more stability. I like the idea at the vertical base one set screw on the side front and then two on the rear area.
Why not just weld up a solid traditional 2 piece vmc base that bolts together with 6, 9 or 12 bolt holes? Weld the frames together, nice thick steel, with supports where need be, fill it with granite epoxy, machine the mating and refrence surfaces for all the rails, embed the slight adjustments for the rails, Scrape everything in! Rock solid industrial machine base, they use this technique for many industrial scale precision vmc's! Thats how im goibg to do mine, even if i have to pay a shop to machine the surfaces and refrence points, if done correctly and sized properly these frames are 5-10k+ with no running gear!! Paying 1-2k for a machine shop to do the mating surfaces properly will still be a farcry from having to purchase a base The smaller you build it the less sense it makes to do it this way.. Im going to build a "knee vmc" about waist height and frame weight approx 3-400kgs I have a bench lathr thats 170kgs and its by no neans a big machine, its tiny and mills need more everything than lathes, more rigid more weight so a vmc thats under 150kgs i doubt will do much and you will very quickly find ita limits and want more Space is a problem for me but i can still fit a solid machine with custom footprint
Thank you so much for sharing. Your thought process is detailed but concise, perfect.
Thank you, I appreciate the kind words.

Yes agree, the tall enclosed was my favorite also.
