Lay the Delrin on a work surface with the side you want to glue facing up.
Use 280-grit sandpaper and sand at a 45-degree angle left-to-right across the entire surface of the Delrin. Do not work to create a smooth surface. The goal is to scar the Delrin.
Repeat the sanding procedure, this time from right-to-left across entire surface of the Delrin. This will create a cross hatched pattern and allow the glue to bond with the Delrin.
Use a shop-vac with a bristle attachment to vacuum the surface of the Delrin and remove any debris. The cleaner the surface, the better the glue will adhere.
Coat the Delrin with a thick layer of epoxy, mounding the glue in order to fill all the grooves when you press it onto the steel.
Press the Delrin to the steel and secure with clamps if possible.
Allow the epoxy to cure according to the manufactures directions.
Things You Will Need
- 280-grit sandpaper
- Shop-vac with bristle attachment
- Epoxy glue
- Because Delrin is such a resistant surface, try using a power sander set on the lowest setting for large pieces. This will help reduce the wear on your hands and arms.
