Capn, thanks for the feedback. On fender nerf bars: I am very pleased with how the ones on my car trailer turned out. I made them out of two pieces of 1x sq tubing with bolt tabs and secured them with large 3/8 inch riv-nuts (so that they can be easily replaced when... not if... they get crunched). Then I formed a piece of aluminum diamond plate, matching the fender, to form a step. The nerf is only two pieces of tube; one perpendicular to the frame supporting the end of the fender; and one angled brace piece. The bent up lip of the step pan along the main frame of the trailer stiffens that leg of the triangle to where it needs no other support or fasteners. Just 3 rivets along the angled nerf tube hold the pan and one in the corner. Very sturdy.
Last night I routed the other 3 clearance light wire ways. On the rear ones, since I had the router set at full depth for one pass in the foam, I did over and under the side table blocking as an interrupted cut, then went back and step cut across the blocking using multiple passes. I hope to glue the clearance light blocks in this evening.
Humidity has been awful here for the last couple of days, but we had a down pouring last night, so not so bad this morning... yet. Local weatherman is calling for near 90's or just over for the next few days. If the humidity comes back I may decide to work on the SS back plates for the clearance lights, downstairs on the mill, rather than up in the hot loft.
