    • Mix a small quantity of 2-part epoxy and seat (1) magnet into marked location.

    • Depending on your printers tolerance, adhesive may not be needed. If using epoxy, be careful not to use too much. The final position of the magnet when fully seated should be flush with the face of the aluminum idle tool bank cooler.

    • NOTE: The linear rods should be inserted until flush with the back of the printed part. Final depth will be set later in assembly.

    • Avoid drilling these holes to achieve a slip fit with the linear rods. We want a tight and concentric bore.

    • NOTE: The rods are secured by interference fit into the printed dock. If fitment is too loose, tool exchanges can fail.
