help with angle iron's

[EdK]

Much easier to read Dave.

Where did you get the aluminum angle iron from? Can you post a picture of it so we can see what you're working with?

You could try using WD40 instead of water. I never use water in the machine shop for rust reasons so can't say its better but I don't think I've ever gone above 320 grit before buffing with the tan coloured compound. I have jewels rouge but haven't needed it in years.

Yes good improvement on the writing.    Like it or not people are judged by the way they communicate and how they look.  One could be as intelligent as Einstein, but have poor communication skills and therefore be looked down upon.  I too hated HS English and I was an undiagnosed dyslectic until I went to a community college.  Eventually with a lot of help and hard work I turned that around and have had several manuscripts published in peer refereed journals.

Your technical skills will also improve with experience.  If there is a community college or vo-tech near by see what they have to offer.  BTW, you'll find the technical instructors very different form the traditional academic versions.  The web also offers a variety of technically oriented teaching sites, especially on YouTube.  Take a look there and you'll probably be surprised at the amount of content, mostly good, but some not so much.

Tom has posted numerous how to videos that I highly recommend.

thanks guys... i did get the aluminum angle from home depot, i cant post a pic right now.
i lent my mother my camera but i think i have another one around here somewhere ill take a look a lil later when i have a min.
so yeh yesterday i did do one 2 foot section and it came out ok not perfect but a hell of alot better than where i started.
i will try and get a comparison shot later if i find the camera.
the part that i did looks great if your standing a few feet away but if you get real close you can still see lil marks
i dont know if this is scratch marks from paper or if it is still the streak marks that was on the extruded aluminum to start with i think its the scatch from paper tho not 100% sure
one leg i went from 320,400, 600 sand paper to sisal with emery compound, denim wheel with tripoli compound and sewn cotton wheel with white rouge.
when i finished that leg is when i noticed the scratch's still there if you look close.
so on the other leg i went from 320,400,600,800,1000,and very quickly with 1500 sand paper to try and get the marks out there then i did the same thing with the wheels and compounds.
that leg was slightly better than the first but for all that sanding and polishing scratch marks were still there (not quite as bad but definitely visible if if your less than a few feet away.
i even got "noxon 7 metal polish" it says it works on aluminum ( oh and talk about the smell it reeks like ammonia )
but any way i rubbed it on and off just like the directions say ( only did this to a small area near the end) and i ended up washing it off. i think it didnt do much and if anything i think it made it look duller not shinier.
i dont know it there is anything better than this brand or if i even need anything like that any way.
any of you guys use any thing like that and find it helpfull?
ok i gota go do some things ill try and post a pic later if i find camera

On soft metals like aluminium small scratches will be visible even highly polished surfaces.
One reason for these small scratches is because all the buffing and polishing takes place in the same direction.  If you can change the direction say by 90 deg. instead of going up and down the length in the same direction it will help.

You will need to change direction after each pass. Can be tedious.

The other thing Dave, we can be or get too critical of our own work. If one looks hard enough - nothing is perfect.  

By the way metal polishes should always done in little circles - no one yet has come up with a better method
