I have been working on the Andy Beasley lumber storage rack. I had some questions from the article and the drawings. I estimated the length of the plywood gussetts at 12 inches by 8 inches high. I double checked the article about the 2 degree upward angle. Now I wonder how that works. I first thought that I would trim off the back of the 2×4 support at 2 degrees, and then trim the plywood gussett 2 degrees before I glued and screwed it to the support. It seems that if I just stick the support arm assembly in the slot and drill the 1/2 inch hole it will have a cantilevered force pulling the bolt out forward. Undeer Heavy load won’t that split the 1×4 vertically? Was I supposed to trim the internal spacer blocks 2 degrees on top instead of at 90 degrees, which now has them level? The 2 degree to 90 degree level connection will have a wedge shaped space under the support arm in the front of the vertical stanchion. Any suggestions.

forces in check they are
Here'a a link to the online article:

To get the 2° up-angle, seems to me you'd want to cut the top end of the spacer blocks to 88° and the wall-ends of the gussets and support arms to 92°.
For an individual shelf to fail under load, the weight would need to be sufficient to split a short section of the two 1x4 uprights between two of the glued-n-screwed spacer blocks on all of the uprights (he has six), or, rip out the end of the 2x4 support arms while crushing all of the 3/4" ply gussets. It might take Yoda to muster up that much Force. ;-)
The thought of what a 16-18 inch wide by 16-18 inch deep group of boards would weigh seemed to raise a pretty big question. I wish I had cut the tops of the spacer blocks at the angle rather than square. I do have the angle on the gussetts and the support arm. I am going to try a couple of decks this way. Maybe later I will try putting the angle on the bottom of the 2x4 tongue that inserts into the uprights. Thanks for your help.
