Altmill on casters?

How feasible is it to mount an Altmill on casters? More to the point, will I need to re-align the mill after a move? Would I need to re-surface my spoil board in order to eliminate any table twist caused by the mill legs to be ever so slightly at different heights?
I have VERY limited space and I suspect that I will have to access the mill from the sides of the machine at times due to it’s size. This will require moving the machine. I might be able to arrange for a couple of feet of free space on one side but in order to access from the other side I would need to then shift the entire machine over.
Am I over-thinking this? Is there little or no concern about the table twisting if the floor is slightly uneven?

I use a leveling caster on most of my tools. They have a base that comes down past the wheel which locks it in place but also helps to level your machine. Just search “leveling casters” on Amazon.

That was one kind of caster I was thinking of. I wouldn’t want the whole thing starting to move. My main concern though is twisting.
Most of my tools are on casters as well but none of them is really that sensitive to alignment.

Yeah they work great. No alignment issues. I still have to put a rack on the legs of the altmill to steady the unit but even then nothing gets out of whack.

Thank you, it’s good to hear that you have had no alignment issues.
