RECOMMENDATIONS FOR FURTHER WORK

1. Chlorophora Excelsa, which is used by TAMTU for ox-cart bearings, should be tested under similar conditions
2. More wear tests should be conducted on impregnated wooden bearings, particularly those timbers which show rapid wear under dry conditions
3. Coefficients of kinetic friction should be determined for impregnated and greased wooden bearings.
4. Tests should be conducted on wooden bearings impregnated with vegetable oil or animal fat (vegetable oil particularly should be beneficial, according to literature, since it reacts with the steel to form a coating)
5. Tests should be conducted to determine the influence of surface roughness of the shaft.
6. The influence of wood grain direction should be investigated
7. The influence of timber moisture content could be investigated, although this should have little effect after the impregnation process.
8. The effect of heat conduction and bearing temperature could be investigated. Using higher values of bearing pressure and surface velocity...
9. Coefficients of kinetic friction could be determined by using a simple torque-measuring method from time to time during the wear tests (e.g. spring balance)
10. Checkout the excellent lubrication properties of BANANA SKIN to see if they can be somehow incorporated into steel/wood bearings (NB - this item added 1999 - Weir).
