Sliding E.Piano/Keyboard Stand for DAW

Need to move your keyboard forwards and backwards under your desk for use with your digital audio workstation? I did! So here's my solution: PVC pipes cut to size around the bottom metal poles of my keyboard stand. I then attached felt fabric to the pipes and wha-la! It took about an hour. Here's a step-by-step with pics. But first, here's what you need:

5' PVC pipe
PVC pipe cutter 
Tape Measure
1 Yard of felt fabric
All purpose spray adhesive (from an auto-store)
Sand Paper
Scissors
Box cutter/knife
Black acrylic paint/paint brush

Step 1: Measure Each Leg

Measure from the inside of the rubber cap to the center beam. Each leg may be a different length (all four of mine are).
