Drafting machine?...

In spite of having used CAD programs for many years (TurboCAD is my most
recent tool, and let's not have this degrade into a Sketchup war, shall
we?) I still resort to (and enjoy!) using pencil and paper for many of
my design activities. I used my Dad's drafting board, T-square, and
triangles for many years, and I still have fond, fond memories of taking
drafting class in high school, one of the two most useful classes I ever
took (typing being the second; and man was that Mrs. Utz a hottie!).
Unfortunately, I no longer have a decent drafting table, the T-square is
long gone, and all I have left are a few triangles and my drafting
pencils and a sharpener. I'd like to rectify that, but then again ever
since taking drafting class I always had a hankering for one of those
fancy drafting machines (like this guy:
http://en.wikipedia.org/wiki/File:Zeichenmaschine.jpg). Does anybody
own one? There are lots of them for sale on eBay; any recommendations?

I still have my K&E and had it rebuilt a few years ago. Fluid drive.
Like silk.
It's not up right now, but will be as soon as I have a place for my
board.
For a quick sketch, to step back, do a tweak, walk into the shop with
it, start building.
For years I had a monitor perched on top my board, keyboard and
trackball on a shelf, and used both systems at the same time.
I guess the big thing to watch for is the problem most machines
develop and that is brake alignment...i.e. when you lock the
mechanics, do the scales stay true to the axis.

K&E was the standard in the drafting rooms I haunted.

We used Vemco drafting machines at Caterpillar until the early 80's
when the digital age was upon us. I would highly recommend Vemco.

Fortunately I got a copy of Wildfire 2 (Pro-Engineer predecessor)
about the time I retired and every project I do I model it with
Wildfire.

Sorry, I don't have any recommendations but you brought back some
memories for me.
The ones we used in college just had the cable and track mechanism.

Mine's a Bruning (same difference, I guess): I love it. Traded a
parallel rule machine that my company discarded for it. Fitted it with a
couple Vemco rules and it's right purty.

A picture of a similar machine:

An example of this is I start to make a sketch of a chair. Then I build a
prototype.
Once I am happy with the prototype I take all the dimensions and make an
ass'y
and detailed drawings. This way I can make some jig and fixture to make
more than
one chair.

An excellent way to work, particularly with chairs. I did a reproduction
one a few years back and kept a fairly good pictorial record of almost
exactly the process you describe.

Since it was a copy, and I had the original as a go by, I got to start
with a full scale drawing:

And, as you say, the jigs developed in making the prototype were the
name of the game. :)

I tend to prefer the parallel-bar[*] tables myself. However, mine
has been
relegated to the Attic since it takes up too much floor space for the
small
amount of time that it actually got used.

[*] Cords on both sides of the reference bar allow it to move
vertically on the table while remaining parallel.

The ancestor of that corded parallel bar is the heavy weight cordless
brass
bar. It was equipped with a low profile gear at each end. The two
gears
would maintain the parallelism of the bar. It was the first tool
that I
used as an apprentice draftsman. Then we progressed to much better
tools
not to mention CAD.

I'm really surprised that they would have started you out with that instead
of T-square and angles.

Not the same thing at all. The corded bar provides a horizontal reference,
the rolling rules don't provide a reference, they just allow a line at a
given angle to be transferred or repeated.

Personally I don't see what the things with wheels bring to the show that
the parallelogram type doesn't.

That device has been around for at least 40 years.

Piece of crap, back then, probably still is.

Was given one which I played with one for about 20 minutes before I
threw it away.

A decent size board is probably the most important tool for making
decent drawings(sketches).

After that, a 45, a 30-60, and a decent scale will solve a lot of
drafting problems.

Throw in a pair of dividers and a decent marine chart and you are good
to go to do some navigation.

Looks like you had the proper training. Many engineering firms had
young graduated engineer working two years on the drafting board
before having project of their own.

I was fortunate enough to go to a co-op school.

All my board time was while I was going to school.

After graduation, my drafting tools just gathered dust until I started
sailing.

I used my engineering tri-scale to measure a drawing. It is in a special long
drawer with a pull down door easy to get to.
My triangles are in the same shoulder high door.
Oh - my French curves are there as well :-)

And I only used them in High School - started with CAD on my 8080 - home brew
and continued on through Cadence PCB / IC software in the end.

I just used triangles.

The chart table (24"X24") on my sailboat is too small to accommodate
regular
size chart.

What do you sail and where?

Landscape drawings also on E-size. I just de-commissioned my E-size or really
any size up to E - actually 36" x 150' long rolls. Shame, the mover broke it
and refused to pay off.

Drafting/Technical school of that day would start you on a classroom
drafting board about 18" X 24" and 36" X 24".

Those boards were only suitable for A, B, and C sizes drawing sheet (i.e.
8½" X 11", 11" X 17" and 17" X 22"). A 24 inches T and small squares were
adequate enough.

(The one I have now is 36 inches long)

However the Ship building and Aircraft industries required layouts and
assembly drawings larger than E size drawing (34"X 44"). At that time,
corded parallel bar and T square were not adequate for an 8 foot long
drafting table. Not to mention that most of the time piles of reference
drawings were stacked at one end of the table.
