| Nov 9 at 23:46 | comment | added | Aloysius Defenestrate | A simple 2x2 added to the front of your original design would create a load path all the way to the floor. (Google ‘site built ladder’ if I’m not describing it well.) | |
| Nov 9 at 7:27 | comment | added | Graphus | "My question is, is this truly stronger than the design using screws?" Yes it could be noticeably stronger. "Is there a better way to achieve strength in this type of shelf?" Any number of ways. Just add glue for one. In conventional furniture-type joinery your second design could be glued only (although you could reinforce if desired). Beyond that, any combination of M&T, dowelled butt joints, housed joints (laps) etc. could be chosen. But unless you're planning on storing barbell weights or engine parts a shelf supported around all sides is a design that's already plenty strong. | |
| Nov 9 at 7:16 | comment | added | Graphus | "The problem with this design is that the entire weight of each shelf is a shearing force on the screws. The longer the shelf (and thus the more things I put on the shelf), the more weight on those same few screws." By all means make something stronger (for any combo of reasons) but just as an FYI you're underestimating the strength of modern screws. Even the lowly, and much-maligned, drywall screw can be much stronger than often stated; but common 'general purpose' screws can individually withstand >80lb in tests. Multiply up from that, use better (and beefier) screws and, "Whoa!" | |

| Nov 8 at 23:59 | comment | added | Ashlar♦ | Although you haven't identified what the loads will be, I believe that your proposed connection will more than take any regular household loads well. I would recommend that the beam at the bottom span between the front posts and the upper one go from front to back. | |
