I have some Stainless Steel pieces (several feet in length) that currently
have a brushed finish. I want to buff / polish these to a mirror finish. I
have a new bench grinder, but I have no experiece with buffing wheels and
compounds. Due to the amount of material, I would prefer to do as little by
hand (sandpaper) as possible, but I ultimately want a nice end result. What
products (stitched wheel, felt wheel, firmness of either, compounds, etc) do
I need to accomplish this? I have tried some buffing, but many of the
deeper original scratches remain.
Any details on procedures and products would be greatly appreciated.
Thanks
180 grit and working it in progressive steps of no more than 60 grit at a
time until around 400 grit but you must sand to the bottom of the previous
grit or scratches will appear during the buffing procedure and or distort
the finsh . As far as buffing there is two steps cutting and coloring
you want to use a ventalated cotton buff with an aggresive Tripoli cutting
compond then use a cotton flannel wheel with a white coloring compound. You
dont say how large thes parts are but im not sure if your bench grinder will
be capable to generate enough speed or have enough power i run a 5 Hp
polishing machine with a 10-12" dia wheel and two pair of gloves on each
hand the parts become very hot and can burn your hands now im not talking
about small thin pieces but larger 16 gauge and up in thickness and larger
parts you find on cars and bikes. Good luck
