Yogi,
I have just re-read your original post,in it you mention how you would prefer an original oil finish, but then describe how you intended to finally use an oil / varnish mix.
This got me thinking, what do people REALLY want.
Is it a traditional oil finish? A high gloss French Polished finish? A hard wearing Urethane finish? Varnish?.
What is the preferable finish Guys?
I think each one mentioned has its usages but whenever we get down to the nitty gritty of a hand rubbed traditional oil finish the information available to do it is often contradictory or even unavailable.
