I made up a brace, quite a bit of work cutting out a chunk of 1” steel plate, I cut it out with a torch, then had to go back and forth getting the draft angle of the casting just right, and test fitting the piece over and over, I ended up with about 1* of angle being pretty close, then fine tuned it with a grinder, and I had to chisel out about 1/4” of filler to get down to the base metal, there must be 20 lbs of filler on this machine. Adding 2 more of these braces, and attaching them together would probably stiffen up the machine quite a lot, but I think I’ll stick with the one for now. I still have a little more adjusting to do with a grinder to get it just right, but column flex is far better than it was.
