Re: Making a custom lazy-susan style bearing
In 2006, team 696 made their own custom 4 point contact turret bearing. It was made from lasercut 1/4" thick aluminum plates, with 45 degree angles milled into their edges where the balls rode. There were 4 plates: inner and outer, and upper and lower of each. The balls were not held in any race, but were alternating steel and delrin. It worked very well. It was very smooth, had no slop, and was able to handle a great deal of load. Lots of work to make though.
