Summary: Learn how to lay out partitions from a carpentry expert in this free woodworking video.
"Hi this is Jon on behalf of Expert Village in this video clip we would be laying out or partitions. On our shelving unit here we have assemble the outside and now we need to measure and lay out for our partitions side which would break up our 3 sections. I want my partitions to come out the same distance of 10 inches as my sides are. However they are only going to extend between my top and the bottom portion cause I have a piece of trim. So I'm actually going to measure it on one side and I get 28 inches. Now if I where to measure that in the center this bottom board could potentially be bold a little bit and give me a accurate reading. Now my measurement was 10x28 but I need to subtract trim on the front side of it. Again that trim is 3/4s so it gives me a final measurement of 9 1/4 x 28. "
