Well here is the first update on the tuning process.
1. Quick things to remember I am not mechanically inclined so this is basically rocket science to me
2. Remember a dremel is still a drill so safety is important or you will learn the hard way like I did and drill your thumb
3. I just started this project yesterday because we have bad weather here in Dallas - this is about 3-4 hours of work (I have two kids and a wife that won't let me work for more than 30 minute at a time)

1. Cover metal pieces you wish to drill in 2 plies of electrical tape which will help prevent the drill bit from slipping; I learned the hard way one sometimes doesn't work
2. Mark the tape where you wish to drill or else you will get holes all over the place; this is more of an appearance thing
3. I used an 1/8" titanium nitrade coated bit which worked well
4. Start slow and increase the speed to get through the metal
5. Remember to "peck" the drill up and down a couple of times to clean-up the holes.
I still have one large hole on the arm left to drill and I am thinking of painting the metal black - any opinions? If so what kind of prep would I need on the metal and paint? Can I use paint for model airplanes?
