If you happen to have this book, maybe you can help me. If you don't and

Lap on the Table Saw",
http://www.amazon.com/Joint-Book-TER...2854848&sr=1-1

If you've never done that before, searching inside books this way is a nice
way to find useful information.


In "End Lap on the Table Saw", page 46, Step #3, the author writes

Lock the fence and clamp the scrap in front of the blade.
Butt the stock against the block and push the cut through with the gauge.


After considering it over in my head for 3 days, I may have the jist of it,
but I think it may be important so I'll post anyway. It beats reading the
political thread. : ) First off, what the author is doing here is making a
cut one side of which will form the shoulder. I had to wonder why he is
working so hard at it (as a beginner, it would not have occurred to me to
make it so difficult). And that is the reason I am asking. I have decided
that it should probably say, "butt the stock against the FRONT side of the
block and against the fence and push...". Yet the author still does not
explain his rationale.

I can see how using the block and fence help ensure a square cut, but I'm
curious why that should be expected to do better than the gauge and fence
alone assuming the mitre guage is square. I saw a similar technique used on
NYW online tonight (free online episode, 1 per month here), though I don't
recall Norm clamping the block.

So it all boils down to: Why is it worth using/clamping an extra block in
place? The idea of putting a clamps on an expensive TS fence seems
counter-intuitive to me. I hope I haven't beat a dead horse...

The block serves only as a gauge to set the cut location; as you push with
the miter gauge, the stock being cut moves past the block and into the saw
blade. There is no possibility of trapping the free end of the stock
against the fence which would result in very bad things you don't want to
experience.

IOW, following the instructions helps keep your body intact.

I should also say that if you are cutting a half lap in only one piece,
there is no purpose to the block...using a block allows you to make the
shoulder cut at the same location on many pieces.

If you are only cutting one, shove the fence out of he way and use only the
miter gauge.

Table saw safety 101--stock should never touch the miter gage and fence at
the same time during a cut--doing so risks getting a piece of stock wedged
between the blade and fence which results in the stock being thrown at you
violently.

The block allows you to align the stock without having it be in contact with
the fence during the actual cut.

If you find "The Table Saw Book" by Kelly Mehler and look on page 65 there
is demonstration of kickback.

You might want to get a copy of that book and read it through--a table saw
can hurt you in some non-obvious ways.

The idea of putting a clamps on an expensive TS fence seems
counter-intuitive to me.

The fence is not fragile in that way. At least it shouldn't be--if putting
clamps on it damages it it was a piece of crap to begin with. "Table Saw
Magic" by Jim Tolpin shows a wide variety of useful accessories that attach
to the fence.

I hope I haven't beat a dead horse...

Safety is never a dead horse.

Actually you need to ammend that comment. That is true only if you are
making a through cut resulting in 2 pieces. If you are cutting a rabbet on
the end of the piece and use the fence as as index to establish the length
of the rabbit you will be fine using the fence and miter gauge at the same
time.

No, I don't.

No, you won't. The piece can still get crossed up and instead of just
getting a cut-off end tossed at you you get the whole workpiece tossed at
you. If you look on page 65 in "The Table Saw Book" you will find a
demonstration of just this occurring.

The one cut where it's safe to work with the fence and miter gage at the
same time cutting a rabbet in one pass where there is no stock between the
blade and the fence. One can stretch that a tiny bit if the piece between
blade and fence is thin enough to reliably break off rather than tossing the
whole lump of stock at you.

Thank you. Safety is paramount. So having the block on the side of the
blade
you are standing on (not sure if this is the front or the rear) provides an
exemption
to this rule?


I just happend to have Mehler's book within arms reach. I looked at it
several few years

Yeah, that was what I was saying. The stock can touch the fence and the
miter gauge and in one pass create a rabbit with no danger of anything
getting caught between the blade and the fence. If you need a rabbet that
is longer than the thickness of the dado set you simply start with the stock
being cut at the end and work your way towards the fence. I was simply
pointing out that it is not always trouble as you had inferred for the stock
to touch the miter gauge and the fence. And you basically repeated my
comment in the above paragraph.

I'm pretty sure I've got it now. So in the situation I described at first,
the block will keeps the stock furthest from the fence from being thrown
back at the sawyer. And since a rabbet is being cut, there is not problem
of using both a mitre gauge and the fence at the same time. Whew!!! Please
correct me if necessary. I may never make an "End lap on the table saw",

Technically, yes, but...you only want the block to be in front of the
blade sufficiently far that the stock has cleared it _completely_
_BEFORE_ engaging the front of the blade .

Absolutely not. See above.

Yeah Bill, the "block" is used as a stop block attached to the fence. You
absolutely do not want a loose piece of wood to become trapped between the
blade and the fence. The block off sets the fence so that there is
clearance between the fence and the blade equal to the size of the block.
You still have to be careful as the loose piece could spin around so if
practicle the block should be larger than the cut off piece, width and
length, between the fence and the blade.

When cutting a rabbet or half lap you really don't have any loose pieces so
a block is not necessary if done correctly.
You should always start on the end of the stock and work it towards the
fence when cutting these type joints.

You use the block to set the position of the piece in the miter gage, but
before the stock engages the blade it should be clear of the block and
supported only by the miter gage.

No. The block doesn't go between the fence and the blade, it is in front of
the blade. You set the stock on the saw so that it is touching the block,
you then secure it to the miter gage using either finger pressure or a clamp
as you deem appropriate, then start moving the miter gage and secured stock
toward the blade. It should slide past the block before it goes into the
blade.

In Step 2, they are just positioning the fence. I believe Step 3 is the one
that has been under
discussion. I think the author should have provided a top view instead.

One of the things I like about the book is that it makes me think, but it
left me with too many
unanswered questions in this example. The book includes a lot of
interesting "asides". It's a nice little book.
I picked it up for less than the price of a copy of FWW at the newstand. I'm
expecting
a little more from (Taunton's) Complete Illustrated Guide To Joinery. I had
a chance to buy it at my
local used book store, and they had 3 copies, but when I went back to get
one they were all gone,
so I picked up this book instead. It has advanced my knowledge of joinery
quite a bit--for any folks
that may at this point know less about it than I do, the central theme is
that glueing end grain doesn't
work, and cross-glueing long grain surfaces does not produce the same
strength as glueing parallel
long grain surfaces. One should also try to take into account the direction
of the rings (since wood is
not stable). It's interesting stuff.

Actually, the second page illustrated the answer to my question... that I
didn't ask. A splitter is just a straight piece of metal, while a riving
knife moves up and down with the blade, following its contour.

Well worth a read, even if you've read it before.
