Yes, it’s only the frame, I have not built the top yet which will be larger. At least 50x75 from what i believe others have done. But I am waiting until I have the Journeyman here and can take measurements directly. I want the table to be big enough to support an enclosure. I need that for two reasons.
Here is one of them.
His name is Ziggy, and like most cats he gets into everything. And in this corner of the basement where I will setup the CNC was one of his favorite things. Since I moved that out I suspect when the CNC gets zipping around to him it won’t be much different than those HO cars and he’ll be jumping up there wanting to play. Which would end in a bad way, mostly for him.
So I can’t have that.
The other reason is the laser. I want the enclosure to protect eyeballs, mostly Ziggy’s because he won’t know not to look at the light and he has told us he does not like to wear sunglasses. We tried; he wanted no part of them. 
It’s not possible to isolate this part of the basement from the rest of the house. And closed doors are against his rules. If there is a door closed somewhere he will sit that and scratch at that door until he digs a hole in it or you open it for him. I think he does it just to mess with me.
