1x12 mounted horizontally on a wall. from the bottom of the one by 12 I want a one and a half by one and a half by 2 ft board coming off of the bottom horizontally out. it'll be square on the left side 45° angle in the right side. from that 45° angle another one and a half by one and a half by 2 ft piece will end with another 45 at the top side. with a one and a half by one and a half by 1 ft 45 on the bottom square on the top to create the end of this arm coming off of the one by 12 then from the top of that one foot piece drawing a line from that point to the top of the 1x12 we will install a wire to support the weight of what we will put in this trough. we're going to have a total length on the 1x12 of 25 ft we're going to put these trough arms that are 2 ft out 2 ft diagonally up and then one foot up from there every 2 ft. but we're only going to put a wire on every third arm See more
