I finally got around to building a new lumber rack, after looking at several designs, I finally decided to go with the stud and shelf support style. Although some people use 2×4’s for the supports, I used plywood on both sides of the stud glued and screwed. I got the frame up and one row of supports then ran out of time, I tapered the supports from 3 3/4” to 2” and there 20” long. I used a taper jig I built from plans I got at woodsmith shop, it works VERY well by the way, I had 40 supports to make and the jig made easy work out of it.
I’ll post up the final picture when I get the other three rows done.
