Dave - You need to slow down Smile  we are trying to help,  may be not as fast as you would like but sometimes that's just how the cookie crumbles Smile

First bit of advice: Because you have not done this before you will need to have a practice - I doubt it will come right the first time.

Second bit of advice: Use what you have - electric drill, air drill whatever.

Third bit of advice: Have a quick go - see what happens - tell us what happened - see if we can help.

ok well anyway i did go put a lil bit more effort into it but i think i put a lil too much emery compound on it . it started making like a black streak when i was ppolishing and then when i would stop for a second there was a couple of patches of stuff that well the only thing i can think of that it resembles is ya know when you try and get a price tag sticker off something and it doesnt come all the way and makes like a lil black blotch of goo when you rub it? well yet thats what i got but i put the wheel to it just to heat it up a lil so it come off easier and wipe it with a paper towel i am assuming it from the emery compound i ran the wheel through a wire brush and well it still looks black all the way around the wheel but its not laying a bunch of crap down any more...so i think i am right so far but my big question is i am using sisal wheel with emery compound then planing on denim spiral with tripoli then cloth sewn wheel with either white rouge or red rouge then maybe a sewn cotton with no compound last does that seem like a ok order???? also i am curious when i should move on from the sisal wheel ( i did wet sand it before 320, 400,600) and i am on extruded aluminum so that has streaks in it to begin with and the scratches from 600 sand paper i did some reading and i thought the sisal wheel and emery compound is suposed to take away all streeks and scratches.... i have been going over and over it and the streaks and scratches are still there...dont get me wrong they are nowhere near as bad as when i started and it is starting to get shiny but if you look close even in shiny part you can still see streaks and scratches a lil bit i dont know if i should move to next wheel or if that would be a waste of time and to keep goin with this one any tips would be apreciated

Another thing that might help you get more responses is to use some basic grammar like capitalizing the first letter of every sentence and ending every sentence with a period. Look at your post right above this one. It looks like one long sentence that's hard to read. Smiley-gen163

So Dave you're not so hot at writing - don't worry about it I'm red hot at reading Big Grin 

You're getting there it takes skill - you have to learn that skill - mainly through doing it and patience and sadly doing it wrong. When you do it wrong pick yourself up have a cup of tea Smile  and just do it again, it is all part of the learning process.

So we could say so far so good Smile . The black gunge will come off the metal with some solvent - paraffin (kerosene) , turps lacquer thinners. It does need to be wiped off the metal every so often.
If it is on the wheel try (very carefully ) to wipe it off on some scrap metal (no solvent) no solvent on your wheel.

As you are finding out it is a slow job and there is no way to do it faster. Take your time be patient and careful, using a rougher grade will get rid of the extrusion ridges quicker but you may end up with many deep scratches which you will still have to get rid off.

To move to the next wheel - from me yes try it, nothing to lose (only a bit of time) see how it goes.

By now you should be understanding that it does require some skill. Smile

so first YES i am definitely horrible at writing always have been never really went to school that much (ended up with GED thats good enough for me) even when i did "english and writing" class was always my worst i hated it. but anyway the piesce i am doing definitely getting shiny i did sisal and emery and denim and tripoli taking a break for tonight getting nice and shiny scratches still there i read somewhere if you wet sand before going to 600 grit was enough but i think i should have gone higher the piece i am doing now is going on the back of the stand i am making so you wont really see it that much anyway thats why i am doing that one first on the rest i think i am going to sand till 800 or 1000 depending how it looks but we will see tomorow i am tired goodnight

Glad it's coming right for you. 800 grit should be fine enough, if you want to try 1000 grit you  need a bowl of water to keep the paper really wet, it will clog very easy with aluminium.

All Ed is saying that because your post isn't punctuated it makes it very difficult for us to understand. Also I need to take a breath every now and then when reading otherwise I get dizzy and fall off my chair. Big Grin 

We have tried to help you now it is your turn to help us, when next time you post lets limit your sentences to a maximum of 25 words, you can use less but not more than 25 words.
End your sentence with a period (full stop).
Start your new sentence on the next line down.
Just like I am doing here, it makes it so much easier for us to read and understand.

Smile Goodnight

ok ill try...question about sanding i dont have a sanding block.
i have been wraping it around about a inch and a half by 4 inch piece of wood and using wet/dry paper.
i have been sanding aluminum angle (3/4 inch legs) i have been clamping it to edge of table and doing one leg at a time.
the one i did yesterday was about 2 feet long maybe a lil bit longer.
now wraping the paper around the wood i would get 5 strips off one standard sheet of sand paper.
and it took all 5 strips to sand this 2 foot segment.
2 pieces each leg and the the last strip just to touch up everything.
oh and i am only doing the out side of the legs since when they go on you cant see in inside (side down to wood) any way.
to me it seems like i am using ALOT of sand paper it either gets cloged up or looses its grit and i have to move onto a new sheet.
like i said it is waterproof paper and i have been sanding with water. (i was told with metal its better to use water)
am i wrong is this a normal amount of paper to go through?
or maybe i am doing something wrong?

Dave, Wow! that post is so easy to read and understand.  Thumbsup 

We really appreciate the effort you went to Thumbsup 

Unfortunately there is sand paper, sand paper and sand paper and it can vary considerably in it's quality.
The type of grit used, how much grit there is per square inch and how well it is 'stuck' to the paper.
I don't think you are doing any thing wrong, it is just the quality of the sand paper you are using.
I also don't think you are using an excessive amount of sand paper.
One thing that may help (a little) use lots of water -helps stops the clogging and keep wiping the 'dirty water' off the leg.

For your first time - you are doing great Thumbsup
