A wheel & bearing assembly my friend gave me. Wheel is 20" dia. shaft is 1.5" but steps down to 1.25" at the wheel. The darn thing is NON-magnetic!!!! Oh, that's a 1lb. spool of 5-cord Kevlar thread sitting next to it. They go for about $75ea. and  I picked up 2 cases of 24ea. for free when the Aerospace company I worked for went Enron. The owner of the building & warehouse said stuff had to be out by Oct. 31, 2002, so a friend & I filled up two large pickup trucks!
