This bracket was designed to square up tubes in a water bottle boss pilot hole drilling sled but may be helpful in other frame building applications.
Other fixtures I have seen for this application reference the down/seat tube miters or OD of the BB. Those fixtures require adjustment to match tube blocks/v-blocks for various tube diameters. This bracket indexes the sides of standard BBs to hold parts square at any height.
I am always open to frame building fixture ideas! If you have a new fixture idea or a suggested mod to any of my existing parts, I would love to hear it!
