This view is looking from the back of the table with the tan being the board added to hold the hinge and drop leaf.
This is also what I has in mind. And of course you would need legs to support the leaf when it was set up. As for cutting a "hole" to drop your machine in to make it flush with the desk top, yes, it can be done. My DH made one for me. Only mine is in a large leaf that I put in the dinning room table when I need added space. He cut the hole, then built a sort of drawer and used L brackets to attach it to the under side of the leaf. It holds the machine just fine. I used it just today to sew the binding on a queen size quilt. Good luck with what ever you come up with.
