I've been wet-scraping "some" lead-painted wood on my house. It is a time consuming process, but yields the best results. There are a variety of profiles of carbide scraper that you will need.

Basically, I set up a catch system, spray the board to be scraped repeatedly during the process to minimize dust, and scrape away. Once its scraped you can easily sand and fill any imperfections, and often end up with a finish that is better than the original.
