I am constantly looking for ways to better my wood shop and that includes making more room for new tools. I had lots of wood in my shop leaned against walls, piles in different places, and also have lots of wood stored in other areas on my property. I decided it was time to make a wall mounted heavy duty lumber rack. Not just any lumber rack, but one that could easily hold over 700lbs per shelf.
Thanks to people on this site like Lew for sending me pictures and tips on the racks they build helped me considerably.
All the lumber, except the filler blocks, are 2×4 boards. The filler blocks are 2×6 as I wanted to make sure these filler blocks came into as much contact with my rails as much as possible. The length of my lumber rack is about 13’ long and the vertical 2×4’s are 7’ tall.
The top horizontal 2×4 support I wanted to be 100 times more secure than I thought it needed to be! The picture you see of the finished rack and partially loaded has at least 1000lbs of wood on it. The bottom self of wood I weighed and it has 355lbs of wood and then I stood on it (210lbs), bounced up & down, and the rack did not ever make a creek. If the top horizontal 2×4 ever comes loose not much would have a chance of surviving under that avalanche. I used ten Tapcon Concrete Anchors (1/4” x 3-3/4”) along with a fender washer on each anchor point. For the bottom horizontal support I used four anchors.
I used Simpson StrongTie brackets and Simpson #10 1-1/2” Structural-Connector Screws to attached my vertical 2×4’s using a 2x block on the top and bottom to ensure I have the right spacing for the 2x rails. As you can see from the finished rack I have five sets of these vertical supports on my lumber rack. For maximum strength I also made sure all my vertical supports rested on the floor.
I was running short on screws and Simpson brackets so for the bottom of the vertical support I just nailed them to the bottom horizontal support. This was not a big concern as there is basically no load on the bottom section of the vertical supports where it meets the horizontal support.
The filler blocks that come in contact with the rail are cut at a 5 degree angle. The back of the rail that touches the wall is also cut at a 5 degree angle. This ensures your rails always tip up so lumber does not have a tendency to slide off. I added a Sketchup drawing of the blocks and the rail. I installed a rail on the middle vertical support first and used this as a level point (both front & back on the rails) for the rest of the rails. My filler blocks are 2×6 pieces 8” long and I used 3” deck screws on both sides of the vertical supports to hold them securely in place.
