Bicycle Frame Jig/Fixture Centering Cone Set - Steel

Set of five centering cones to build a bicycle frame welding jig/fixture.

The two larger cones are for the bottom bracket, the medium cones are for the head tube, and the small cone is for the seat tube.  You will need to determine if these will work for your bicycle frame jig build. Some people use the larger cones for the head tube and medium cones for the bottom bracket.
