there is one thing on this that i need to modify, i need to make a deflector for the air coming off the internal cooling fan on the motor, at the moment it is directing a lot of the metal shavings at my face. just something to think about, any metal shavings in the eyes just wouldn't be good. The fan seems to direct the air flow towards the table, and the light aluminum shavings like to go where ever the wind takes them.
