Welcome to the english page of the Polishing guide, this is were you wont have to read in swedish =) ..i will show you in a simple way how to make aluminum and other metalparts shine. I am an amateur at this and the guide is intended for nonprofessionals who would like to make their turbo, IC-pipes valvecovers and other engineparts have an amazing mirrorlook. I made this guide during the winter 2005 when i was rebuilding my toyota Supra 7MGTE 3.0i turbo engine, and now i made it into a separate website.

I have created a Facebook Group in two sections. One International and one Swedish. The Group is here: Facebook Polishing Group

Step 1. This is the aluminum intakepipe on the 7MGTE supra turbo engine that is very visible on top of the valvecovers, sitting there looking quite ugly normally.. but thats about to change! Very rough surface with pores and marks from the casting as you can see:

Step 2. First i used a file to remove aluminim castingmarks. This will make very rough scratches but the file will remove unwanted material very fast, and that is what i want:

Step 3. Thats a little better.. or at least its a good start of a long day:

Step 4. Here you can see how rough an aluminum casting surface is and very deep scratches the file made :

Step 5. Now its time to make the aluminum surface smoother! I used the 3M scotch grinding tools on an ordinary electric drill with an extra chuck. The smaller chuck with quick-lock makes it easier to reach without damaging the aluminum surface. Here we go! Warning – aluminum dust is very hazardous to inhale!

Step 6. After a while the aluminum surface looks much better. Lots of heavy scratches but the surface is much smoother. Prepare to spend some time at this stage. As the surface gets smoother we can see pores, and of course they show were we dont want them… were they are most hard to grind:

Step 7. I decided to get rid of these casting marks too for a cleaner result. Very heavy grinding tool, almost to much unnecessary violence:
