Hi idon'tknow, and welcome to the forum
I'm facing the very same dilemma here in my 1936(or38?) Bungalow...junked floors and only a little $$
But--I really think doing it myself is going to be well worth the effort. And for you too
Anyway, I'm still in the researching stage of refinishing these old floors. I came across a website in my research that I thought you could use:
I can't say how 'good' the site is until I've actually done my floors, but it seems to cover everything. I hope it's helpful, please let us know how it goes!
