I’m building an adjustable height workbench but I needed a lifting mechanism to raise and lower the middle shelf. I decided to use 2 trailer jacks (Curt 28204) and 1/2″ rod to connect them. This same design could be used to make an adjustable height desk.
No one part of this project was difficult, but everything took a little longer than expected. The end result seems very sturdy and is a good foundation to build a workbench/out feed table from.
