Thank you for the quick reply! I would like to remove the machine altogether, but just tipping it back would be OK too!
The machine says "Regency" ZigZag. (First pic).
There is a nub in front that keeps me from tipping it back. (Second pic) The nub looks pretty permanent. I looked at the bottom of the case to see if I could take off the hinges. The screw for the hinge looks like plastic and could be a one time use only type of screw.
I hope the pics help!
