I'm finding that I'll be needing a plow plane for my next project
(have been making do by cutting dados w/ an assortment of other hand
tools) --- does anyone have plans for such?

It doesn't need to be adjustable (save for depth which is a necessary
part of the functionality?), so should be much simpler than most of
the images I'm seeing of them on-line.

Any guidelines or resources anyone could suggest would be welcome.

Thanks!

William
