My wife picked up what I expect was a beautiful garden bench at one time in it's life from a garage sale. It has metal rails on the side with and a metal inlay in the back surrounded by a wood frame, and wood slats for the bench portion of it. I suspect in it's previous life, this is how it might have looked.
Problem is at sometime in it's life the previous owner spray painted it a sickly grey, the entire thing, metal, wood, all of it. It's pretty horrible. I can sandblast the paint off of the metal and give it a good paint job, but for the wood I'm pretty sure sandblasting would be a bad idea -- In fact based on the fact that it was painted, I probably just want to replace the wood. I can rip wood and do various fancy cuts in straight lines for the bench seat, but unfortunately, the top of the back rest is curved. What is the best way to duplicate the curve of the existing piece I have?
