I could do that but they are very hard metal. I think I would
be exhausted if I had to do a lot. I wonder how the manufacturers
do it. I mean polishing, that is!
Depending on the shape of the stake & the accuracy required on the
finished item there are several ways industry might polish these
items. Most of the ways require some type of machine, lathe,
cylindrical or centerless grinder.
A way that most folks could use is a belt sander and/or angle
grinder. Th is requires the use of tools generally available (in
the US) at well equiped hardware stores and any industrial
supplier. Belts of different grits are available at these locations
also, however, a better selection of belts is available from a
company specializing in abrasives (look in the Yellow pages of your
phone directory). The majorit y of abrasives (in the US) are mfgd
by 3M or Norton Abrasives.
Depending on the shape & size of the stake, a narrow width (aprox
1", 25m m) belt might be required. If push came to shove, you could
always get abrasives in 'shop rolls', various widths by about 50ft
& grind/polish sh oe shine fashon. The final polish can be done
using buffs or a polishing arb or or a right angle grinder.
