So I just visited an antique store the other day and I ended up buying about five old estate pipes, four of them are in perfect shape and will only take a little work to get back in working order, the fifth one I bought because I really wanted a challenge as a beginner. The pipe itself, has a not very deep crack in the chimney and was wondering how to repair that would I sand it down, putty it, and stain it then it or what should I do; also sorry for not posting pictures since I don't know how to, and I do really want to give it a try at repairing it.
