Anyone have any plans or ideas on making a home made heat treat oven
of say 10 x 12 x 15 inches or so in size? Electrical operated and
running off 220 preferably, definately no propane powered furnace is
wanted.

Gingerly gives you enough info to do this. See "big bertha" or suchlike.
Its for a round furnace, but the idea can be extrapolated to anything.

What I would be really impressed by is a homemade neutral atmosphere
furnace !!!


Absolutely, or a controlled atmosphere one (same thing?). If you've seen
parts that have come from such a furnace, it puts things right in
perspective. The heat treat facility that I used to use controlled their
atmosphere with natural gas, which seemed to work beautifully. How I
hate the scaling and the decarburizing of heating in the typical furnace
after seeing how nice it can be.
