I'm calling it a jig because it's really not a wheel truing stand. I've been wanting something to check the runout on my wheels. And, maybe tackle a wheel building project one day.
I had heard about Alumaweld rods and found some on sale at Eastwood for $5.00 shipped. I bought them and put them in my tool chest for some future project. Because of this, I decided to build my truing jig out of square tube aluminum.
Bought a piece of 1" square tube aluminum (36" long) at a home store for $11 and cut it to size.
