We just fixed up our 70's era house and everthing is great except for
these ugly dark brown construction grade flat slab interior doors all
around our house.

I was determined to spend the time, per some articles I read on the
internet, on using each door as a template to triming a replacement
door, but then I read on one web site (askthebuilder.com) that "some
home centers now have specialized milling machines to manufacture a
replacement door from your original door") I'm paraphrasing a bit but
that was the basic idea.

Anyway, I called all the Philadelphia area window/door retailers as
well as a lumberyard and when I asked about such a machine they
basically figured I was crazy or something.

Has anyone heard of such a machine at a home center? Otherwise, I'm
stuck with the prospect of cobbling together 9 replacement interior
doors manually.

We have lots of little ones, and as such we are not looking for fancy
doors. I was simply hoping to replace these 30 year old cheap looking
hollow core doors with some newer, paneled, cheap hollow core doors.
