Exactly! :thumbsup:The only support I added are these to all legs:
I added them to prevent the shown movement for the top beams, even when it should be naturally prevented by the tabletop, also they were added to relieve the joining screws from part of the mill/lathe weight.

I used 3 layers of 3/4" Medite (medium density fiberboard from Home Depot) over an eight-legged structure made from kiln-dried 2x4 and 4x4 Doug fir. It's screwed to the floor and to the studs. The dimensions are about 30" by 9'. It feel solid and is plenty stout enough for 500+ lbs of bench-top machines.
The best part is the galvanized top. I highly recommend this as part of your build. It was cut to dimension by the local sheet metal shop - total cost was something like $60 or $70. (I have no idea if that is a good price but the guy's shop was so clean, organized and empty that he obviously had little work, so I wasn't about to ****er over a few bucks). I don't remember the thickness - just that it was the thickest stuff he stocked. It makes a great surface because it cleans up easily and you can stick down a magnetic indicator base anywhere you want. It is fastened only around the edges by th aluminum-angle edging. It lies quite flat without being attached in the middle.
One nice design feature is that there is a cutout along the wall in the middle of the bench that is about two feet long and maybe three inches wide. This provides a place to hang the various electric cords out of the way so they don't lie on the bench. This helps particularly with the cables from the mill and the lathe to the DRO readouts. The cables are pretty long and can't be shortened so it's nice to be able to get them out of sight and out of the way.
The spaces between the legs are sized for three tool chests that hold most of the tooling and such.
For a backsplash, I used particle board that comes covered with a white plastic surface, also surrounded with aluminum edging for appearance and protection. It's probably not all that durable but it doesn't need to be. It looks nice, the plastic is easy to clean, and that's about all that matters.
All in all, this has worked out pretty well.
Excuse the mess but I'm in the middle of a project!

I don't know why anyone would want bigger machines. These look really big compared to my Sherline stuff!
Seriously, they are big enough for what I want to do and for the space I want to use. I know that people often feel pressure toward getting something bigger but I'm not there (yet).
The mill is bigger than it looks in photos. It is plenty powerful, more than enough so for the maximum 5/8" shank size. I haven't come close to exceeding its capacity and ability. The lathe can swing a 6" chuck without straining and with a 30mm spindle bore, it can handle bigger workpieces than many comparably sized benchtop lathes. Most of my turning is AL but I've done steel and S/S without being disappointed. Many machines better automate the threading process but I'm not in a big hurry. Changing TPI means changing cogs but for the threads that we use on lights, this usually means changing just one or two and it doesn't take very long.
I went through the same shopping and evaluation process as many others have described here and in other machining forums. I recognized that as a relative beginner, it was risky for me to buy used, though I know that a lot of folks have and like old American iron that works great. I'd love to have a good South Bend or maybe a Hardinge HLV (when I win the lottery, the first thing I'll do is buy a new one) but I'm not confident that I could be sure of getting a serviceable unit and I don't have the expertise to renovate a machine. Also, that isn't how I wanted to spend my time. The same line of thinking applies to the Chinese machines. There is some good and some bad and the recurring theme is that most can give good results if you are willing to do some fiddling, sometimes a really lot of fiddling and head-scratching.
If you take used and Chinese out of the mix, there isn't much left. The Wabeco distributor is within reasonable driving distance, he supports what he sells, and the machines are very nicely made. Some people say they are overpriced and that may be true in the judgment of some. Right out of the box, they work with smooth precision like a Benz or a Leica. Working with high quality machines is rewarding in and of itself and maybe someday I'll be a good enough amateur machinist to deserve the privilege.
