I have the same problem. I bought an old cabinet that someone had totally refurbished and I bought it for $5 at a second hand store and it's too small for my Singer 401 Slant O Matic. I so want to be able to put my Singer in it, also. I would love a lift and a bigger hole that fits it perfectly, just like you want. It's been sitting in my garage for two years. I almost took it back to the second hand store, but thought better of it.
