Good idea
I agree, but I just went out to my shop and turned the heat up and lights on to look at mine. My square tubing does Not have open ends as I thought so it would need to be opened up as Crash suggested. Its typical square tubing and it does have a seam, but the sides are not dished enough to make a big difference. I could get a .006 feeler gage under the middle when a Starrett machinist square used for reference. It could be the powder coating also. As long as the linear rails are parallel and the bearings don't bind that's really all you need. The rest can be setup correctly.
If you insist on making a large milling machine capable of .001 work then you will never be happy. As long as you have adjustment, the frame does not need to be 100% perfect, you can make it work.
Frankly it might be easier to do it my way as the plates can all be made in a machine shop and then installed directly on the top square tube. But Crashes way may be faster and get the job done.
The poster who said send it back has no idea of the size of this machine and the difficulty getting a very large double pallet and packing it up. Where else are you going to get a welded steel frame machine at this price point? Especially when the fix is so easy?
