I was wanting some advice...which I know you good folks have plenty of.

I have a No. 40 plow (wooden beam) that I was considering restoring.  However, I really don't know where to start.  Should I completely dismantle the entire plow?  The steel seems good there being only surface rust (hasn't been outside in decades).  Should those be sandblasted?

Any great ideas, hints, clues or warnings would be greatly appreciated!

Thanks all.
