Polishing

Buffing wheels.

For a good polishing of aluminium parts, you will need buffing wheels with different hardness.
I bought this form an classic car show. The are available for drilling machine, as well as for buffing motors.

 

Buffig motor.

This is my buffing motor.
It is a standard AC motor with 1500rpm.
Its better to get one with speed regualtion, but my one is working also.

 

Buffing compound.

Also you need buffing compound with different grains.

 

Starting basis.

As starting basis i used a guiding tube.
At first i grind the aluminium until there are no scratch in the surface. I used a sandpaper with 180 grain.

Advice:
Always wear a dust mask , safety glasses and work gloves when buffing.
