How close to the Blue Water or Ambassador bridges are you? I live in Macomb Michigan which is about 45-60 minutes from either. I forgot to mention that I also have a small machine shop in the basement, so as a last resort I (just in case I can't weld onto it) we could mill it out. I don't have any carbide tooling, but there are plenty of tooling supply centers around here. A carbide end mill would cost you about $30, but we can cross that bridge if we come to it. If you can get it to me I will gladly give it a try for free. Marines rule...TT members rule...Way to take care of your own guys! Awesome offer of random kindness!
