First, locate hole #1 and #6 (mark the centers on the work). *Then
connect those centers with a line.

Draw a second line through #1, and mark off six equal spacings on
that second line (any spacing that comes out evenly on your ruler
will do). *Adjust a bevel so that one arm is on the secondary
line, and the other arm connects #6 secondary to #6-actual.
Then with that bevel set, trace from the other marks on the
secondary line to the original line.

I hope the OP could follow that - cause I sure couldn't...

It's the compass-and-straightedge method to evenly divide a line
segment: make a second line that is measured off into N equal
bits, connect the Nth mark on second line to the end of the primary
line segment to make a triangle, then (using a bevel in this case
to replicate the angle) by simlar triangles, construct the equally
spaced points on the original line segment. * It doesn't really need
any ruler at all (dividers can make equal-size divisions).

An interesting method. *Here's the first hit for a webpage describing
the method:http://www.mathopenref.com/constdividesegment.html

Sometimes geometry is much easier than algebra.

I apologize in advance if the flash app at the top is something
undesired. *I don't have flash installed on my system so I can't see
it.

Now that's a method I was not at all familiar with. *I didn't get that from
whit3rd's description, but that method would require a lot more description
for me to have understood that.

It's also more work than is necessary. The bottom construction isn't
really needed, which means the compass isn't needed either. All that
is needed is the line/angle that connects the free end of the
constructed, uniformly divided line to the free end of the line that
you want to divide.

Replace the constructed line with an already divided measuring device,
like say a ruler, and it's a lot simpler. ;)

That's the same thing my spreadsheet came up with a couple of hours ago,

He could want the edge of the holes 1/4" from the edge of the 6" board.

I took 6" -1/2" for both borders - 4 1/2" for the holes and ended up
with 1. Divided 1 by the number of spaces, 7, and got .014285" for the
spaces, then I drew it. '~0

Well, this *is* basic math: all you need is simple arithmetic (addition,
subtraction, multiplication, and division). What complicates this one is
the
use of a measuring system that's approximately a thousand years old.

You have a total of 6" less two 1/4" borders = 5 1/2" to put the holes in.

Six 3/4" holes take up 6 * 3/4" = 4 1/2" of that 5 1/2", leaving 1" for
spaces
between the holes.

Since there are 6 holes, there will be 5 spaces between them. You have 1"
total to make 5 spaces, so each space will be 1/5".

The distance between the centers of the holes will be 3/4" (the width of
the
hole) plus 1/5" (the spacing between holes) -- this will be difficult to
measure with tapes or rules marked in inches.

I suggest you choose one of the two options below instead.

Option 1
-----------
Increase the size of the borders by 1/32" to 9/32". This will leave you 5
7/16" to put 4 1/2" worth of holes in, leaving 15/16" to divide among five
spaces between holes.

15/16" divided among five spaces = 3/16" per space -- and *that* you *can*
measure easily. This gives you a distance between centers of 3/4" + 3/16"
=
15/16".

So mark the center of the first hole at 9/32" (the width of the border)
plus
3/8" (*half* the width of the hole) = 21/32" in from one end. (3/8 = 6/16
=
12/32; 9/32 + 12/32 = 21/32)

Subsequent holes are centered every 15/16" from the
21/32 + 15/16 = 21/32 + 30/32 = 51/32 = 1 29/32
1 19/32 + 15/16 = 1 19/32 + 30/32 = 1 49/32 = 2 27/32
2 27/32 + 15/16 = 2 27/32 + 30/32 = 2 57/32 = 3 25/32
3 25/32 + 15/16 = 3 25/32 + 30/32 = 3 55/32 = 4 23/32
4 23/32 + 15/16 = 4 23/32 + 30/32 = 4 53/32 = 5 21/32

Option 2
----------

Redo everything in metric. It's SO much easier.

A number of years ago, I was in Toronto on business. Having utterly failed
in
my attempts to find a metric tape measure at home, I asked one of the guys
I
was working with where I could find a hardware store. He wondered why; I
told
him -- and he asked in honest bewilderment what on earth an American would
want with a metric tape measure. My answer was that I'm a woodworker, and
solving problems such as this is FAR easier with measurements in
millimeters,
rather than fractional inches -- as you're about to see, too.

It's much easier to find metric tapes in American hardware stores now than
it
was in the 1980s. So go buy yourself a tape measure that has dual scales
(inches and millimeters). That will make it easy to see the relationships
between the two systems.

Then remeasure. You will find that:
- your block is 152mm long.
- you want a 6mm border at each end.
- you want to evenly space six 19mm holes.

152mm less two 6mm borders leaves (152mm - 6mm - 6mm) = 140mm.

Six 19mm holes occupy 6 * 19mm = 114mm

You have (140mm - 114mm) = 26mm available for the five spaces between the
six
holes, so there will be (26mm / 5) = 5.2mm between each hole. Ignore the
point-two millimeters; you can't measure that fine anyway.

The holes will be centered every (19mm + 5mm) = 24mm.

The first hole should be a distance of 6mm (the width of the border) plus
9.5mm (half the width of the hole -- round it off to 10mm) = 16mm in from
one
end of the board.

Subsequent holes are centered every 24mm after that:
16mm + 24mm = 40mm
40mm + 24mm = 64mm
64mm + 24mm = 88mm
88mm + 24mm = 112mm
112mm + 24mm = 136mm
And looky the the last hole is (152mm - 136mm) = 16mm in from the end,
same
as the first one.

Isn't that a lot simpler?

I used to work designing and creating artwork for business forms. If they
were to be run through a computer printer they had to be designed and
created with precision. I still have a number of forms design rulers that
have scales in various inch units such as 5/32", 5/64", 1/12", 1/6", 1/3",
1/10", 1/5", all the regular multiples of 1/32" common most rulers in
addition to metric. Spacing in typesetter's points where 72 equal one inch,
with scales in units such as 5 pt, 5 1/2 pt, 6, 7, 8, 9, 10, 12, 13, and 16
point multiples.

I find that these scales are valuable in woodworking as one can find a scale
to fit any need, plus they are stainless steel and almost indestructible.

As I recall. you measured the resulting line and divided it in half at
the middle, then repeated this with the resulting segments on either

No he doesn't, he wants 1/4" and 6mm doesn't equal that. Close but

No, but it sure makes the calculations a LOT easier. Reduces the risk

Sure. Tell that to the group that engineered the Hubble Space Telescope

Huh? What did MKS/FPS have to do with Hubble's mirror shape?

And consider these two standards:

Strawman. An inch is defined as 2.54cm.

The one the tools use. The problem is that we now have both. I can work with

That works for certain number of holes (2^n-1) holes but not for an arbitrary
number of holes. The OP wants six holes.

This problem is essentially the "trisecting the angle" geometry problem, which
has no solution (bisection is possible, but an arbitrary number is not).

I'm surprised that no one has yet mentioned (unless I missed it) the old
trick of using a ruler, selecting a number of arbitrary evenly spaced
markings corresponding to the number of holes needed, then angling
the ruler diagonally across the workpiece (or on a bench where the
workpiece is laying, if necessary) until lines drawn perpendicular to a line
parallel to the holes match up with the selected ruler marks. No
math or arithmetic necessary. Unfortunately easier shown than explained,
but some older woodworking books have pictures of the technique.

This method has been mentioned. The problem is
that even though
the hole centers are spaced equally the spaces
between the holes differs.
i.e. The space between the left border and the
first hole as well as
the space between the last hole and the right
border are twice the
space between the other holes. It's up to the OP
to decide if that is
acceptable.

out how to space the holes.

That was a damn sight easier to figure out ... just mark the profile of
the biggest ass on a board, add two more just like it using the Sears

Lengthwise for spacing, widthwise for use, right?

Just about any free CAD 2D program will do that for you including Sketch-it
or whatever it's called.

It's called Sketchup and I'm surprised Swing and Leon didn't mention it.

Simply draw a line the distance you want, "select" the line with the
select tool (space bar), right click on the line and choose "divide"
from the resultant pop up window. Move the mouse along the line and it
will be divided into whatever number of divisions you want, and based on
the length units you use(window/model info.) I use 1/16th's. The red
dots show on the line, and the distance between the dots is given.

Once you have the right number of dots, click and it puts invisible
markers (invisible until you roll over them) so you can do whatever you
want with them, or just write down the distance and have at it.

For 6 holes in 6 inches you need 7 segments, and each hole will be
55/64's or 7/8ths. I can't see 64ths so 14/16th work fine for me:-)

The bonus is, since you are in a cad program, you can draw up whatever
you want the holes for, and see what it will look like:-)

I haven't read all of the messages before this one, so please excuse me
if this has been suggested. But why not build a *paper model* (you don't
need high-power computer software for this problem). Cut out a 6" piece
of paper and some circles (use a marker and color them black if it helps
you see them). Then move them around until it looks right to you and
then tape them in place. Then you have a model which you might use in
any number of ways. I think more things have been built working like
this than by designing with cad/cam software.

It would probably be easier to read the OP, It is simple math , no
computer model needed. I only drew the model to prove the easy math.

Doesn't matter what size the holes are if you want 6 equally spaced
holes in 6 inch length, then the center marks will be the same
regardless of hole size, long as the size fits.

There are lots of ways to solve this long standing problem, as this

This would be inaccurate or laborious or, in my case, both.
Particularly in this example where the spacing between the holes is
small, you better cut out your circles accurately.

I think more things have been built working like this than by designing with cad/cam software.

The reason cad software was invented was to make doing this stuff both
simple, accurate and visually useful. My "cad" software of choice is
Sketchup, and it of course has a simple tool for the job built in, as I
described.

If you have a PC and do woodwork, Sketchup is free and does have a tool
for this, just as Twayne up there suggested.

====================

I would definitely use CAD software (Autosketch) for many layout required
jobs in woodworking but not for this simple example / problem.
Just do it on your calculator and then lay a decent 1/10" scaled ruler down
and mark the hole centers. Or convert as closely as possible to fractional
inches or fudge the borders to make it work out.

Note there are many woodworking calculators that can work in inches and
fractions for you, too.

It does matter, he wants a 1/4" border in addition to the even spacing
and he wants the holes to be 3/4" as opposed to what you stated,

"each hole will be 55/64's or 7/8ths"

And FWIW the holes will have 5/32" between each and the 1/4" border.

Your method equally spaces the holes however it does not provide equal
spacing before and after the first and last hole.
