ceiling fan support
Have cathedral ceiling with no support joists, but have one rafter about 4 inches off center...ceiling angle is 18 degrees. My scenario is to cut a 2X12, angle sides to 18 degrees, drill 4 inch hole in center(which I have split two pieces of 2X12 already trying to do...any ideas?), mount the fan box in the hole,secured by steel rod across top of 2X12 so it won't fall through, and mount the finished 2X12 to ceiling center, using lag bolts to attach to the one rafter and regular wood screws on the other side to attach to the ceiling boards. Is there a better way...without cutting into the ceiling and trying to span rafters with a 2X4? Also, any ideas for quickly cutting that 4" hole in the 2X12 for the electrical box? I tried, using a 3 inch hole saw, but don't know how to enlarge it to 4 inches without splitting the wood...which I have already done on two pieces. Any ideas are appreciated, as long as I don't have to cut into the ceiling and can mount the thing dead center, not angled on the ceiling. Thanks.
