Standard 6-32 Setup
This is the lightest method for retrofitting to an existing leaf spring setup. This will work with pretty much all existing carbon leaf springs. The pictures to the left show how I attached the wheel carriage to my Pete Models Leaf Spring. I used 3/8" OD 13/16" tall aluminum spacers for a 6-32 screw. The washers need to be approximately .5" in diameter. I Inserted the screw with a washer into the top of the leaf spring, then put another washer on the screw, put the spacer and wheel carriage on the screw then a washer and 6-32 lock nut. This setup allows you to tighten the screw down on the spacer and leaf spring and allows the wheel carriage to have .0125" of movement up and down on the spacer to prevent binding. The 3/8" diameter provides a wide bearing surface on the carbon and because the connection to the leaf is very tight there is little chance of wearing and fatigue.
