- | Benchtop Buffer ((photo by biknut of the XLFORUM http://xlforum.net/forums/showthread.php?t=494417)) | | + | ===== Using a Benchtop Buffer ===== |
+ | |||
+ | A bench buffer is great if you can take the part to it. That does limit it's use somewhat however. \\ | ||
+ | |||
+ | Keep seperate buffing wheels so you don't cross contaminate polishing compounds. \\ | ||
+ | Apply the polishing compound onto the wheel. It doesn't take much. \\ | ||
+ | |||
+ | You can tell when you need to apply more from how clean the polish surface starts becoming. ((biknut of the XLFORUM http://xlforum.net/forums/showthread.php?t=494417&page=2)) \\ | ||

+ | |||
+ | ===== Using a Bench Grinder ===== | ||
+ | You can put an auger on a bench grinder for a buffing pad. \\ | ||
+ | Apply alloy polishing soap (hold onto pad) and work away. Reapply soap every 30-60 seconds. \\ | ||
+ | Work in multiple directions. Then polish with jeweler's rouge soap and finish with a wool buff on drill and chrome polish. \\ | ||

+ | ===== Using a Hand Buffer ===== | ||
+ | |{{:techtalk:ref:tools:hand_buffer_by_hippysmack.jpg?direct&300|}}| | ||
+ | |||
+ | ===== Using a Dremil Rotary Tool (or similar) ===== | ||
+ | The Dremel type rotary tools will run up to over 25,000 RPMs. \\ | ||
+ | But you don't want to try polishing metals at those speeds. \\ | ||
+ | It is best to start with around 8,000 RPMs and adjust up depending on the size of the polishing pads. \\ | ||
+ | The smaller pads can run at faster speeds. Most of the pads come in either 3/8" or 7/8" OD. \\ | ||
+ | Obviously the 7/8" pads last much longer if you run them at the right speed. \\ | ||
+ | Top speed on them wouldn't be much over about 15,000 RPMs or the wool polishing wheels will start flying apart on you. ((Graywolf of the XLFORUM http://xlforum.net/forums/showthread.php?t=2070932)) | ||
+ | |||
+ | These are nice for getting into small areas but they can leave swirlies that have to be rubbed out. ((ReddTigger of the XLFORUM http://xlforum.net/forums/showthread.php?t=494417&page=3)) \\ | ||
+ | You can control the swirls if you use the wool polishing pads and the buffing compound. \\ | ||
+ | Try running it at little slower speed if it is still leaving swirls. Keep the pressure real light. \\ | ||
+ | Let the compound do the work. Move slowly back and forth with the pads. \\ | ||
+ | Straight line movement just like sanding wood grain and there should not be any swirls at all. ((Graywolf of the XLFORUM http://xlforum.net/forums/showthread.php?t=2070932&page=2)) \\ | ||
+ | |||
+ | The 1" buffing bits will fit most places and the small 3/8" felt bullet shapes fit into most screw recesses. ((https://www.chuckhawks.com/harley_polish.htm)) \\ | ||

+ | |||
+ | ===== Using an Electric Drill ===== | ||
+ | Use the biggest wheel that will fit the mandrel you have since the smaller ones can streak. \\ | ||
+ | You can use 2" and 4" wheels on an electric drill at about 2000 RPM. ((https://www.chuckhawks.com/harley_polish.htm)) \\ | ||
+ | Those wheels won't fit into all the little spaces, so this is also limiting. \\ | ||
+ | |||
+ | A felt buffing pad works well (better than a thumb and wider than a dremel, so no little swirls). ((ReddTigger of the XLFORUM http://xlforum.net/forums/showthread.php?t=494417&page=3)) \\ | ||

+ | ====== Sanding ====== | ||
+ | ===== Scotch-Brite Pads ===== | ||
+ | Scotchbrite pads can work faster than sandpaper. \\ | ||
+ | They will contour to the workpiece, especially curves and round corners. \\ | ||
+ | |||
+ | Start by wetting the pad with water and dish soap. \\ | ||
+ | Go over a given part in one direction for the green pad, rinse thoroughly. \\ | ||
+ | Then go over the part again at a 90° angle for the next finer grade pad. ((HOMER308 of the XLFORUM http://xlforum.net/forums/showthread.php?threadid=925547)) \\ | ||
+ | Repeat until you're satisfied with the finish. \\ | ||
+ | |||
+ | * Below are three grades of Scotchbrite. These can be found online or some hardware stores. | ||
+ | * Your typical green (found in most kitchens) | ||
+ | * Red (very fine grade) | ||
+ | * Gray (ultra fine grade) | ||

+ | * Silicon carbide abrasive: | ||
+ | * Silicon carbide is a synthetic mineral that is very sharp and commonly used for low-pressure applications such as paint prep and finishing. \\ While silicon carbide breaks down faster than aluminum oxide, it produces a finer finish. | ||
+ | * Aluminum oxide abrasive: | ||
+ | * Aluminum oxide is a hard, blocky mineral that provides high cut-rate and long life. | ||
