This took about 3 hrs using different mops on my old bench grinder with a bit of wet and drying first. Fast and polishing can't be used in the same sentence.
Shame you were not nearer you could have had my 3hp 10" pedestal mop polisher rarely used.
Two methods you can do as have done but dont bother with anything above 600gr then mop polish.
Or use the mop polisher and go down in grit size then on to a callico mop. Its not like aluminiums where it rips holes and burrs them over called over polishing.
Give you some idea one abrasive has to be kept refridgerated, slap on the mop and sparks will fly off steels like a grinder.
If its long strips of brass a handheld polisher might be better but weigh a bit.
thats cool mate, what was it for, just decoration? and im guessing ally?
well im 150+ hours into polishing now and have found the fastest was so far is to flatten the material with 800 grit on my da then block with 1200 and buff using autosol this seems to give a better shine and faster than the proper compounds
I have polished literally hundreds if not thousands of metres of brass flat bar angles and curved sections i cant heat the brass too much when buffing as it leaves swirles in the brass and the customer cant have this as it has to be a perfect mirror shine with no marks for their very very expensive furniture , they are happy with the time its taking to get the results they want
