This is the third one I've done so far using that old table tops. the others are full size machines treadle or electric
There is a rim that screws around the bottom edge, that could go right back on. Or you could also install that and cut a drawer frond into the rim. This top extends to the rear a bit far for most people, that could be cut and hinged, so a drop leaf read section..
I've seen parlor cabinets that have an iron frame inside,
all toll I might have around 4 hours into making this thing ..
a tip, if you do something like this always make sure the machine bed, when finish sit just a hair above the tops surface. if not the fabric when slide to the needle will want to hang up.
