Problems with emery compound

[hue]

I have already finished sanding all the way up to 1500, I then buffed with brown then white it came out great except the small scrathes, so i decided to go for some help, after going through this forum i decided to try the emery with a 4" sisal wheel to try and get better results. I finshed all of the compounds and then took a look, for some reason it is dull it never happend when i used only brown/white but now its just not as polished looking as before. any help on this would help a ton thx's

Sounds like you just aren't spending enough time with each compound. Use each compound until it won't get any shinier and then move on. If you overlap your runs at 45degree angles it will move faster.

Make sure that your buffing tool is turning enough RPM's. When I switched to a 3500RPM bench grinder with a 6" wheel, the results where incredible. Try and stay away from the 4" buffs as much as possible.

Ditto! Stay away from 4" wheels unless you need to get in a tight spot where a 6" just won't fit, and what RPM are you running at? with a 6" wheel on a 3500 rpm grinder using emery compound you should start seeing a decent shine already.

I have a drill which says (0-2500 min-rpm) will this be enough power for the 6" wheels. also to marsfroggie's post 45 degree's from what? the last compond or the last pass with the buff? I also hade another post wher i was told to go with the sanding marks (when buffing) to eliminate most scratches and for best finish.

I was digging through my tools a found my die-grinder from campbell hausfeld, on the case of the grinder says 25,000 RPM MAX @ 90 psi. That number seems a little big so what im asking is if the number is true will this be better to buff with?

[marsfrogie]

Make your first pass with say emery, then come back over it at a 45degree angle with the same compound. This cuts the metal down faster. You Just keep alternating the cuts until you get it how you like it. Do the same for each compound. Caswell's metal polishing guide has a more detailed description of the cut and color motions.

thx for your help, i accidently hit my frame with the arber shaft and had to re-sand from 320-600 then i got inpatiant and started buffing with the 45 degree angle thing and it came out better then the spots that i buffed before at 1500. i will finish sanding till 1500 again and re buff.

The next thing i was wondering, whats the best hand polish to use when done with the compounds? i heard mothers wasnt that good, any suggestions?

[marsfrogie]

You can put some duct tape or something to cusion the impact on the arbor shaft to keep it from damaging your work too badly when you mess up. I like to use Mother's polish. I have also heard that eagle one polish is good. Make sure you go over it with a pure carnauba wax after you polish it to protect the shine. Caswell claims good results with Flitz, but I haven't tried.

thx i will definatly put some tape on the end of the shaft (good idea). and i think i will try the flitz... ill let you know how it goes....thx again for the help
