I started with a Delta brand kit that includes four corners and wheels. You are supposed to add hardwood 2×2’s to complete the mobile base. Rockler and Woodcraft sell similar versions. I picked up some 1.5” square steel tube at my local steel yard, and made this heavy duty version for my DJ-20. I cleaned the raw steel pieces with some mineral spirits, then primed and painted them. After drilling the holes at the drill press, I was ready for assembly.
The steel tubing is 1/8” thick, and fit the corner brackets well. The foot operated lift handles the 500 lb. jointer without issue. When the foot pedal is released, two rubber feet firmly contact the ground.
Two fixed wheels at the outfeed side are always in contact with the ground. $30 worth of steel transformed this inexpensive kit into a heavy duty mobile base that will last.
It is performing well, and helps me easily move the aircraft carrier around my shop. The base is solid, with no trace of vibration. I would recommend this option to anyone adding a mobile base to a large jointer.
