I dont have a large shop…at all. I needed a place for lumber though. I took inspiration from The Wood Whisperer for this wood rack and am very pleased with how it turned out. In Marc’s plans he used 3/4” plywood, i didnt have any of that and didnt want to wait to borrow a truck to get a sheet. I did however have 3/4” MDF, so I used it. The uprights are attached to wall studs in 5 or 6 places with 4” screws. The arms are a 15” long 2×4 sandwiched between two pieces of 3/4” MDF. The MDF is longer than the 2×4 to create an open mortise so to speak. They are attached to the uprights using 2-1/2” screws (2 per side).

Pretty straight forward, but oh so needed.

Not sure what the weight capacity is so I dont have a lot of wood on it yet. If any of you know what kind of capacity i could expect that would be great. My main concern is if the MDF would be just as strong (or really close to it) as the plywood would have been.

Thanks for looking.

I finally replaced the MDF with 3/4” plywood….the MDF held up with absolutely no problems but I needed to get the cedar off the floor (150 bd ft). Most of the boards were 10’-13’ long. I cut the majority of them down to 8’ lengths. I kept about 6 of them at original length just in case I ran into a situation where I needed a long board. That being the case I needed to put in some extensions. There will be a shorter shelf on the bottom to hold the cut offs from the cedar.

Nice Rack! ;), I would seriously be watching the MDF brackets though. MDF is not really good in structural applications. It would definitely be looking for signs of failure over time. You could easily redo the brackets when you come upon some plywood scraps.

yeah i have been keeping an eye on it. so far so good. i have about 90 +/- bd ft of Cypress and some miscellaneous cut offs right now. i have 100 bd ft of Red Cedar but i am afraid to put it up, i dont want this thing to fall. i will definitely replace the MDF with Plywood down the road. thanks for the input.

I’m planning on doing one ASAP too. I’d keep an eye on the MDF. Something you can do is add another horizontal bar above the whole thing (right above the middle arms), stick a nail in it to have a reference point, and precisely measure the distances of the arms relative to the nail from time to time to check if your MDF moves (which means: have an Excel spreadsheet handy, enter your measurements, and plot them out). At least that’s what I would do (probably will actually even if I do mine out of plywood).

thats a good idea Sodabowski. i am hoping that since the MDF is 3/4” thick it will do fine until i can replace it with ply.

I wish I would have done something like this. I used 3/4” pipe as my lumber supports drilled into 2×4’s. I tried to drill the ¾” holes at the same angle, but my pipes are no way close to being on the same plane for each shelf. Maybe an upgrade is in my future???

yeah it was really easy to make sure they are in the same plane on this one, with the edges being square and all. good luck on your upgrade. PS. use 3/4” plywood, i have seen your shop and wood collection.. you need high weight capacity…. :)

“The uprights are attached to wall studs in 5 or 6 places with 4” screws.”
Are 4” screws long enough? How deep did you countersink them?

Jesse, they are countersunk a little over halfway thru the 2×4. very sturdy.
