Frame Alignment Fixture

A friend was getting into bicycle frame building, and asked if I could make an alignment fixture.


Take a visit to the metal monger, and round up the usual suspects.  Looks like a plan is forming…

Ready for pickup.  Future plans involved a granite surface plate, so I made two separate mounting studs.  The outer diameter of the upper clamping nut sleeve will fit inside a self aligning concave/convex washer assembly, retained with the snap ring.

Another view.
