T5 Belt jig

I needed a solution for connecting T5 timing belt components after conducting several trial runs. The most effective approach was to fuse the belt together using a soldering iron at 260-270°C, but achieving an overlapping joint that melts as much of the belt material as possible required a three-fingered configuration. This jig enables you to insert a thin knife blade (0.8mm) into a custom-designed block within a T5-belt holder (designed for a 10mm wide belt). The blade is then used to cut evenly spaced slits in the belt. The resulting two ends of the belt will have two slits each, necessitating removal of the middle section from one end and the outer sections from the other. This process creates a three-fingered joint. Next, use the T5-belt-holder to secure both ends in place and maintain precise alignment for the teeth, preventing any pitch misalignment. Finally, melt the finger joint together using a soldering iron or an alternative method that suits your needs.
