Getting ready to wire a log cabin, but this one has a beam and perlin roof system and i have never done one of these before. Hoping for a few ideas here the roof consists of beams then the tongue an groove ceiling finish then felt then insulation board then furring strips and then the sheeting and shingles. They have got the t&g and the insulation up wnd want me to wire the ceiling lights including 16 cans. Got any idea how you run your wires in this mess and also what would be the best way to cut the t&g for the slope cans? As always thanks for the help......
