I have had three major designs of splash containment. For my #2 PCNC1100 I spent some time on trying to get it to look clean/good. I also had a few minor updates I did over the similar one on machine #1.
Big feature is I can still access the control panel, I like that option since I didn't want to relocate it. It took quite a bit of time to fit the sheet metal but all in all it is a very simple design. I used ball bearing pulleys for the door rollers and they ride on a 1/4 CRS rod. This makes for a smooth opening and closing of the doors even though the tops just slide steel on steel. All the weight is supported on the rollers. The full width tube steel is 1x1 and the doors are framed with 3/4 x 3/4 TS, all the sheet metals is 20ga steel except for the top in front of the control panel and it's 16ga Aluminum.
I didn't want to move the machine arm to the front corner like my other mill and like to have everything right there so I mounted all the controls and screen on the right door. The doors are 18" wide each and clear a 6" Kurt as well as my 8" 4th axis motor.
