| For my test item I chose an upper tripple tree
off of a 75 honda super sport. I am only going to polish a section of the
tree so that you can see the results. I have already put the tripple tree
in B2B parts cleaner. This parts cleaner is an extremley agressive paint
stripper. You can use whatever paint stripper you like though. I have had
my best luck with the B2B. I use the parts cleaner for carbs, when it gets
too dirty for Carbs I strip parts with it.
The picture on the right is the Tripple Tree I will be using. |
 |
| Here is a close up look at the tree. You can see that the black paint does not like to come off and that after more than 20 years of abandonment the trees look pretty bad even after stripping off the paint. |

Once you have stripped the paint off of the part that you desire to polish.
(Or in the case of parts like Master Cylinders the coating will not strip
off.) Clamp the part into the vice. Make sure the part is snuggly in the
vice and remember to have some type of rubber padding on the jaws of the
vice. |
 |
| The medium pad will leave visible scratches in
the aluminum. You can see the scratches in the picture to the right. Don't
worry this is normal. That is why I have Fine pads.
If you want to make the tree completely smoot or alter the shape some you can start with a course disk instead. then go to the medium disk. Because this is a demonstration peice I started with a Medium disk. |
 |
|
I then twist off the medium pad and go to the Fine pad. This pad leaves a really good looking finish. You will notice right away that the aluminum has a grain. If you move the pad up and down and left and right you will find what direction the grain runs. Polish the Aluminum with the grain and leave a few scratches as possible. When you are done with the fine pad you will see a noticable improvement over the Medium stage. Once you are done with the fine disk you may wish to use the small file
set to shape the peices that you can't get to with the disks. On a side
note the 3m disks are about an inch smaller than the Craftsmen disks and
can reach into some areas that the Craftsmans can't. If you choose to
use the files youi may want to touch up the filed spots with the fine
pad again. When you are happy with the results it is time to buff the
Aluminum. |
