| MECHANICAL PROPERTIES |
High mechanical strength in all categories. |
| WORKING PROPERTIES |
- Cocobolo machines well with sharp hand and power tools
- Moderate blunting effect on cutting edges which must be kept very sharp
- A reduced cutting angle is required for planing or moulding and the surface can be rendered very smooth to the touch
- Must be pre-drilled
- Use Epoxy for best result
- It takes stain and can be brought to an excellent finish
- Difficult to glue wipe joint w/ acetone or denatured alcohol and use 2 part epoxy for adhesive.
- Water based finish only other likely not to stick
- Swirly grain more likely to tear out
- Spiral cutters are quite effective
- Dust can be an irritant on skin or lungs
- Proper safety precautions advised
- Will darken with exposure to UV light
- Must take care to not expose to excessive dry heat
- End grain especially susceptible to checking
- Very hard to dry below 12% mc
- Quite workable at 12%- 16% mc but finished product must be kept away from excessive dry heat
- Material thicker than 2” very likely to check
- Wiping joists with acetone or denatured alcohol will decrease resin on joint surfaces
