One of the first bike frames I picked up at a swap, I made the nubie mistake of not checking if I could move the seat post before cleaning and painting it. 
I snapped the end of the stuck post off, then welded an old crank and a pedal axle in it and pounded and twisted, and heated and oiled but it was stuck. Then it just sat in a corner for a couple years.
I decided to install a fixed seat post to use the frame. A study of 3 of my most comfortable bikes led to 28.5 inches crank centerline to seat top.
To bolster strength, I inserted a chunk of rebar like 6 inches into the existing stuck post and welded it in.
Then tapped a standard seat post cut to length in place and welded on the frame at the base and at the top by the end of the rebar.
Finally, added a collar made from a China Schwinn frame and bolted and tacked it in place. Then some primed and new paint tomorrow!
Not sure how I want to go with this one. I still have the maroon color paint, but I may change it up something brighter.
