The layout can be done using a stick. The concentric arcs are drawn with the stick/trammel.
I wanted to hear you shingle pros discuss cutting the shingles themselves, which are all inverted keystones in shape, the included angle decreasing as you move out.
You were going to cut them, right?
Or were you just gonna draw the lines, and let me do the shingling? :laughing:
BTW, housebuilding work sucks around here and has for about the last year. No end in sight. My waiter last night, was wearing a nice tie, and used to be a carpenter. I told him I would snap his pic, since he looked so well turned out, and he could use the pic in his Contractor Talk signature. :w00t:
