Polishing an anvil & bench block
I am unable to find the original question, sorry, but I have an
answer about how to polish your anvil and bench block.
Harbor Freight carries a “Polishing Kit” that fits either 4" or 6"
angle grinders. The kit comes with 6 polishing pad disks ranging
from 40 grit all the way up to 800. I was able to polish my blocks,
stakes and anvils to a very bright and level surface with the use of
these. You definitely want to watch the thickness of the polishing
pad for wear-down while you use them or you can leave a nice nick
from the center post of the tool on your freshly polished surface.
Keep the face of the pads nice and level while you are working so
your anvil/blocks keep a nice and level surface. I would also try
not to let your anvil or blocks get too hot, although I don’t think
you can ruin the temper with just the heat from an angle grinder’s
pad, but to be cautious I let mine cool off when they started to get
pretty warm. (Yes, if you have an apprentice to do the job you are
much better off, as it is very messy work. It can be time consuming
too, depending on how damaged the surfaces are. It took me about 3
hours of work on my large anvil, and about 2 hours total to do my
smaller bench top anvil, my stakes and my 4" bench block. They are
shiny and new again, and the large anvil was badly dinged from years
of use by its previous blacksmith owner.
I will add in here that Blacksmithing swap meets make for great tool
shopping! I got my 68 pound anvil and 2 wonderful stakes for a total
of less than $175.00. Get in there early to get the best used tools.
I have even been able to purchase some very nice used files that
just needed a good cleaning. Those files that are too dull to cut
anymore, I buy to forge into knife blades. (Well, I no longer have
access to the forges I used when I was in college, so next year I
will be shopping for the even bigger toys, er…tools!)
Definitely do the job OUTSIDE, (TONS of steel dust), and ALWAYS wear
an industrial grade respirator when grinding steel. The usual eye
and ear protection, are appropriate as well.
Hope this helps whoever was asking.
