Related to my yesterday's vise refurbishing project, where I milled a
little thin layer off the anvil to make it look smooth. I used a 5/8"
carbide endmill. I made multiple passes, each time removing a "strip"
approximately 1/2" wide.

While the result is perfectly acceptable for a vise anvil, it was
nothing to brag about as far as finish quality is concerned.

Here's one revealing pictu

The ridges you see, are visually exaggerated by the fact that some
passes fere from left to right and some were from right to left. They
look bigger than they are because of this. In reality they are not
really that high.

So. What would you do, to achieve a decent looking flat finish,
without a surface grinder or anything of the sort.


Wrap a piece of coarse-grit wet-dry sandpaper around a flat piece of
metal, and wet sand the surface flat by hand. Change sandpaper often.
If the mill has done its work well, it will not take very long before
all miil marks are gone. If desired, use finer grades of sandpaper to
eliminate the frosted surface. This can be carried to any extreme,
including mirror surfaces, which seems extreme for an anvil surface.
Unless you are a jeweler.


Joe, I agree, I think that 5-10 minutes with sandpaper will get me
covered.
