nice holder you made for drilling the screws. i forgot to mention that also. a guy can do a lot without needing a mill or lathe, but in my opinion, a drill press is a must.
I did the same thing myself and also made a guide to hold the tap's straight while tapping the holes, being a machinist has it's perk's.
Light travels faster than the speed of sound,,,this is why some people seem bright untill you hear them speak.
