Use a nail gun or hammer and finish nails to connect the cross supports to the upper and lower 2×4 side rails. All outside angles are 60 degrees. The two shorter pieces have an inside angle at 30 degrees. The long piece is 22.5″ from outside edge to to inside edge. The 2 shorter pieces are 11 1/4″ from the inside to outer edge. Click here to see a video I made explaining the angles.
The topic of lumber confused me mainly because I couldn’t find a simple summary of the topic. I found a lot of complex discussions with different terms used by different “experts”. I am by no stretch of the imagination a lumber expert, but I’m very good at simplifying complex topics so that everyone can understand. As a result, this is a simple practical guide to help you understand how wood moves, what wood to buy, how to buy it, and where to buy it.
I built my coffee table!! I used the plans at www. EasyWoodwork.org to build mine – highly recommended you check those out too. They are detailed and super easy to read and understand unlike several others I found online. The amount of plans there is mind-boggling… there’s like 16,000 plans or something like that for tons of different projects. Definitely enough to keep me busy with projects for many more years to come haha
