I'm building a mobile lumber storage rack like this one:
http://www.woodworkersjournal.com/plans/index.cfm/plan_details/5/13/1865
The plans call for heavy duty lumber shelf standards, which are a little pricey. Years ago I built a lumber storage rack (from a WoodSmith plan) using 1/2" pipe. I drilled holes into 2x4 uprights at a slight 3 degree angle to insert the end of a 16" piece of black pipe. I then used the pipe as the shelf supports. Is there any reason this wouldn't work for this cart? Would it weaken the 2x4s too much when I drill the holes. I used my other rack for several years and never had a problem with the drilled 2x4s. Any thoughts from others?
