I changed jobs recently and replaced a daily bicycle commute with a home office - great to work from home, but no commute took a toll on my exercise routine. Answer? Treadmill Desk!
Three basic steps to building the desk, all go into each in detail
1 - Gather materials
2 - Remove and remount controls
3 - Build and install desk
Step 1: Acquire Materials
You will need:
1 - A treadmill - doesn't have to be top of the line, but should be stable and relatively quite. I used a Nordic Track C2200. From Craigslist - $120
2 - 1/2 sheet 3/4 finish grade Plywood
3 - Wood screws
4 - scrap 1x1
5 - 2ea 3-way PVC Elbows
6 - ~ 3' 3/4 PVC & 3' 1 1/2 PVC
7 - 2ea large hose clamps
stain and paint as desired
Your materials may be slightly different based on the treadmill you use.
