Mount Fabrication Procedure

Equipment is PR-15 Mounting Press, LECO.

Making Acrylic Mounts

1. Put sample and powdered Lucite into the mounting press. VIEW
2. Raise pressure to 500 psi and turn on the heat. VIEW
3. Wait for 11 minutes, then turn the heat off.    
4. Increase the pressure to 4200 psi. VIEW
5. Set to cool for 3 minutes. VIEW

Making Bakelite 1.25 Inch Mounts

Procedure by Ruth Kramer.

NOTE: The bakelite procedure involves heat and pressure. This is unsuitable for some thermally sensitive samples.

1. Clean old Bakelite from top closure. VIEW
2. Turn pressure release valve clockwise until snug.    
3. Pump piston to top.    
4. Place the sample flat (upside down) on the piston top. VIEW
5. Lower piston to bottom by turning the knob counterclockwise. VIEW
6. Add 20, 25, or 30 ml Bakelite for 1.25 inch mold, depending on sample height. VIEW
7. Put screw in place and screw all the way down, then back off ~1/4 turn. VIEW
8. Turn on the heat, turn knob clockwise, and pump the piston pressure to the red dot on the middle scale. VIEW
9. Wait until the heater light turns off, plus an additional 8 minutes. VIEW
10. Cool for 3 minutes. VIEW
11. Release the pressure (turn the knob CCW), unscrew the top, turn knob CW, then pump the piston up and remove the mounted specimen. VIEW
