Like many others here, I've purchased the Hitachi M12v router and it's gone
on to be the favorite of my 4 routers. Many posters complained about its
plunge action tending to stick. When I purchased it, I fiddled with the
angle of the handles until the stickiness was *nearly* gone. Well, I have
used it for awhile now and its not operating as smoothly as before. While
missing the newness of the action, a couple of synapses fired in my brain
and reminded me of an old article in FWW regarding router tuneups. After
digging through the many shelf-feet (sf?) of issues and getting sidetracked
untold times, I found the article and applied its recommended procedures to
my M12v. WOW. Silky smooth action has returned. Actually, that's not
quite right, it's better now than it was out of the box. As a matter of
fact, it worked so well, I got my old Craftsman plunge out of mothballs and
tuned it up as well. Again, works better than new (still has the ARHA
For those interested, it's issue 152, December 2001.
Just had to share.
That was a _very_ special issue -- devoted to the use of higher math in
furniture-making. It was numbered accordingly. "Aleph sub minus three"
(ask a math major for an explanation of the joke, if needed. :)
There are various "sizes" (for lack of a better word) of 'infinity'.
They are identified using the Hebrew letter 'aleph' (looks like an '8',
sideways). the size (or technically 'order') of infinity is indicated
by a numeric subscript)
There is an 'infinite' number of regular polygons, with a radius of "1".
There is an infinite number of regular polygons with a fixed number (say 4)
sides (by varying the size). this is the 'conventional' "infinity" (aleph
zero, or aleph sub 0) The number of such items is 'uncountable', but _merely_
uncountable -- you can do a one-to-one mapping of them onto the set of
There is, thus, an "infinity of infinity" of regular polygons, when you
can vary both size and number of sides. this is 'aleph (subscript)1'
(You have an 'uncountable' number of sets *each* containing an 'uncountable'
number of objects.)
Next, if you relax the restriction that the polygons be 'regular', you get
another (higher) order of infinity
Extend those objects into 3-dimensions, and you get even higher orders of
*NOW*, if you 'extrapolate' (always a risky business! :) things the _other_
direction, 'aleph (subscript)-1' could be "arguably" taken to be either
'one', or 'zero'. (discussion over _which_ of those values is correct is
rather reminiscent of Lews Carrol's "Jabberwocky".) "Aleph (subscript)-2"
is something "infinitely smaller" than _that_ value (whichever it is).
