>My answer is to set up my laser shoot down the top of the longeron, and check with a piece of white cardboard how level and straight the longeron is. I should be able to shim it to within near perfect. As perfect as a laser that is. I can do the same with the verticals and the bottom longeron as well. >Is this too anal? Well I figure we have the technology why not use it? +++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Close is good enough. Each KR is a "one up" aircraft. Any part you install need only fit in that location and has no relationship to anything else (another KR). Good joints are a must and the airplane must be built (rigged) true to fly correctly but beyond that don't worry about perfection. Use whatever tools it takes to make the job easier. Larry Flesner
