Finishes?


#1

G’day, whilst we are on this metal ‘finishes’ kick, it is a good
long while I saw circular polishing - at one time it was fashionably
visible inside most cigarette cases (OOH! naughty words!) and in the
backs of many watches. It isn’t often one might want to do it, but it
is simple enough to do. Best to do it via a drill press. Simply fit
a short piece of wood dowel about 3 - 6 mm diameter into the drill
chuck, after ensuring that the end of the wood is dead ‘square’ - at
right angles - to the length of the wood. You could instant-glue a
tiny circle of abrasive paper to the end of the wood. Then lower the
wood rotating at a medium speed gently on to your flat work, moving it
about 4 mm at each ‘cut’. Try it first on a bit of scrap. Or you
could mix a little vaseline with powdered abrasive, apply it to the
end of the wood and off you go! Cheers, – John Burgess /

Hi John, In the U.S. this finish is called “machining”. Another way
to do it is to use an end brush and tripoli or bobbing compound. Have
a good day. Tom Arnold

Tom, I’ve not heard it called machining but “engine turning”…can be
done with a dowell dipped in abrasive. Jerry in Kodiak

Jerry,

Engine turning is done on a special type of machine that makes
precision patterned cuts.
