also watch my dust collection improvment mod here...
My focus on this project: Large vertical support and plenty of space.
Since my workshop and even other rooms were cluttered with lumber pieces I decided to build this organizer to have all pieces at a one site and organized by lumber size.
My second approach was to avoid bending of stored lumber which often occured as result of leaning against a wall.
For this reason I build it pretty high to get most support as possible for the taller lumber pieces. Also I used small angles for the support wall to avoid bending.
Hope you like it :-)
Hope to have one soon
