King, I would suggest it might take 20-50 hours depending on what tools and experience you have. I have never "clocked" my time as I may take a year or more completing a project because I do it in my "spare" time. The key is patience and sharp tools. Use some good transfer agent to mark the high spots and take off less than you need at first and keep fitting. You will make a few mistakes, we all do, just post back here and there are great folks who will help with the solutions!
