I picked up an exterior door with two thoughts in mind.
First was to salvage the 20x30 glass since it is old and has the dimples and is wavy. No particular project in mind just think it may come in handy. So I carefully removed the molding and salvaged the glass.
Second, and more importantly, was to salvage the wood. I scraped a little finish off to reveal beautiful Chestnut that could be useful for some project. Who wouldn't like to get their hands on a couple 7' Chesnut 2x6s. I carefully removed all the nails and got my spreader clamps. Surprisingly it started to come apart pretty easily. It was than I saw the glue lines and alternating grain on the tenons. The rails & stiles were essentialy veneered blockboard.
Guess I should have looked at the bottom edge of the door before going through all that trouble. All the 'wood' went in the dumpster this morning.
