When the trimmer racks for your trailer don't fit the budget or you just want to save money, build your own. Use solid oak or another hardwood that's able to withstand the elements. Choose clamps that make it easy to place and remove the trimmers on the rack.
Prepare the vertical pieces for assembly. Place the two pieces of oak measuring 2-by-60-by-3/4-inches flat on a work table. Measure from the ends of the pieces and make marks at 1 and 2 inches. Make marks on those marks that are 1-1/2 inches from the long sides. Drill 5/16-inch holes through the pieces on the point where the two marks cross.
Mark and drill the adjusting holes for the horizontal pieces. Place the two pieces of 3-by-60-by-3/4-inch oak flat on the work table. Measure from one end and make a mark on the lumber every inch. Put the combination square on the marks and draw lines across the 3-inch side of the lumber. Make two marks on each line that are 1 inch from the long sides. Drill 5/16-inch holes on the point where the marks and the lines cross.
Attach the rubber clamps. Measure from one end of the vertical pieces and make a mark every 12 inches on one of the 2-inch sides. Put the combination square on the marks and draw lines across the lumber. Make a mark on the lines that is 1-inch from the long sides. Hold the clamps on the point where the marks and the lines cross and secure them with the screws provided.
Assemble the rack. Set the vertical pieces on top of the horizontal pieces. Align the holes in each piece so the distance between the vertical pieces is the needed distance. Secure the pieces with the 5/16-inch bolts and nuts.
Secure the rack to the trailer. Stand the trimmer rack upright against the side of the trailer. Slip the square u-bolt through the trailer side and the holes drilled in the horizontal pieces. Put the washer over the threads of the u-bolt followed by the nuts and tighten the rack to the trailer.
