Step 1: Plan it out
The sliders occupy roughly 1" of space, so my needed to be ~ 30" x 18" or so.
The frame needed to be able to hold its shape and not flex, and it needed something a bit more substantial than one single hole to hold the dowels. i decided on something like this:
Step 2: Materials
1 1" x 2" x 8' piece of wood. $2.09
3 1/2" x 48" wooden dowel $4.17
1 set of drawer sliders $5.48
Step 3: Tools
1/2" drill bit.
Drill for making holes. A hand drill would work, but it would take a while.
Miter saw. Nice clean cuts. A hand saw works just fine, but again, it would take a while.
Tape measure. Measure twice, cut once. Or if you're like me, measure one, cut once, measure again, curse, cut again.
Hammer. I used a combination of nails and screws to put this together, so I assume you know what it'll be used for.
Step 5: Sand
I started off with a rougher 220 grit, then 600, and finished off with 800.
Step 6: Time to drill some holes
I only had one clamp, so I ended taping the two pieces of wood together and making the top piece. Be sure you leave equal amounts of space on each side.
Step 7: Voltron Assemble!
I assembled the frame first by tacking it in with finishing nails, then drilled pilot holes and put in a screw per side. After some adjustment I glued the dowels in with some elmer's on steroids.
Step 8: Rails rails rails
Step 9: Now for the wardrobe....
Unfortunately, I must have messed up my measurements somewhere, because my drawer was about 1/4" too narrow and the sliders kept popping off. i ended up using a washer under each screw to remedy the problem. Remember kids, measure twice!
Step 10: Tada!
The rack doesn't come out completely, but more than enough. If you wanted it to come out further, you could get a set of full extension sliders that roll on ball bearings and such, but I opted not to since they cost more than twice as much.
