Nice sharpening & photos!

For some strange reason, as I looked at the crosscut portion of the
photo, I had a mental image of a Galoot T-Shirt, with the cross cut
teeth running across the chest and the logo, "Got Fleam?" he he he...

Followup; I've refiled with a smaller file, which results in narrower
gullet bottoms.

I've added one more photo to the bottom of the montage

May I suggest a quick application of layout fluid on the teeth prior
to the final pass?  The spray stuff is easily applied, and the
overspray is likewise easily removed when the pass is completed using
[drum roll, please] layout fluid remover.  Between start and finish,
it disappears from each tooth as it is filed.  If interrupted, you can
leave the saw for a month, year, or whatever, and pick up right where
you left off when you subsequently secure a round tuit.  Works a lot
better for me than candle soot, BTW.

Oddly enough, I was at the local flea Sunday and a vendor had what he
called a "boroscope", an inspection scope with eyepiece and a 6' long fiber
optic piece for internal inspection of airplane wings, inside house walls
or anyplace else you could get an approximately #14 gauge wire into. It
even had the spot for an external light source. I never asked what he
wanted for it, but I should have since he was selling stuff cheap (I got a
2 foot 4 fold ruler in need of cleaning from him for 50 cents).

I may have to go back and get it this Sunday, since another guy is supposed
to be bringing a box of woodie molders now that I relieved him of the last
2 he had in his truck, along with a nice long Enderes paring chisel that is
actually not bent (hard to find long chisels that have not been used for
pry bars in these parts for some reason).

One of the local auction houses handles surplus auctions for Indiana
Universtiy School of Medicine, and they on occasion have some really neat
stuff such as dentist chairs and optometrists eye testers, but I have never
seen them sell an X-ray machines yet, just X-ray film developers. Silly

If you're working in the "approved way", with your filing
guided by the size and position of the flats generated by the jointing
operation, no pencil mark is required.

If you can't see the flats, you probably shouldn't be filing
the saw ;-)

Would the porch be interested in an (OT) exposition
of how I took those shots?

Wow, the saw filing results demonstrated a definite attention to detail, 
but the camera set up and image processing was quite intricate!

Did you require a crew of "roadies" to haul and set up all of that 
equipment?  And, how much beer did the crew consume?  :-)

Since several people expressed an interest, here's the low down on how I
got those photos.

Executive summary: it wasn't point 'n' shoot; it involved lots of light,
close focus, HDR.

The long version...

The problem with saw teeth is that they're small, and made from shiny
metal. The size problem is easy to get round if your camera will focus
VERY close. Mine will (many compact digital cameras will).

It's a Canon A630,
http://www.dpreview.com/reviews/specs/Canon/canon_a630.asp and will
focus down to 1 cm (under 1/2 inch, Paddy).

It also has manual focus (that's a pain to use, but it has it).

The problem then becomes one of how do you get a camera so very close to
the subject; I have a Benbo Trecker tripod, where the main column can be
adjusted to be horizontal, and the camera facing down. I have often used
this to get "looking down" shots on flat items (books, saws etc).

http://groups.google.com/group/rec.photo.equipment.35mm/browse_thread/t-
hread/0a097027cee21607/b06c28ed3cd2cfc9#b06c28ed3cd2cfc9
http://tinyurl.com/3d9phs

But in this mode the only way to adjust the height is by adjusting all 3
legs on the tripod, which is tedious.

I adjourned to my workshop and made a tripod-extension-widget: http://g-
alootcentral.com/components/cpgalbums/userpics/10152/camera_extend.jpg

This simply has a standard mount thread (1/4" UNC) at one end (from Lee
Valley, thanks to ALF)
http://www.leevalley.com/wood/page.aspx?c=3&p=40361&cat=1,43455,52800

and a camera fixing bolt (same spec...) at the other. In the middle it's
a simple sliding slot, held by a 1/4" bolt and wingnut. This allowed the
camera's height to be fine adjusted easily. This extension ain't exactly
rigid, but it's fine indoors, where there's no wind, and I use a shutter
delay of 5 second to allow any movement generated by camera handling
(pressing the shutter) to die down.

http://galootcentral.com/components/cpgalbums/userpics/10152/saw_how_to-
p_close.jpg

The light is supplied by 4 angle poise lamps; using multiple light
sources reduce shadows.

http://galootcentral.com/components/cpgalbums/userpics/10152/saw_how_to-
p_long.jpg

Of course, if you simply take a photgraph under these circumstances, you
will encounter major issues with over/under exposure, since saw teeth
(especially freshly filed ones) are rather shiny.

The answer is HDR, which has been described elsewhere better than I
can do it:

http://en.wikipedia.org/wiki/High_dynamic_range_imaging

The task at the point of taking the photographs is to shoot a "bracketed
set"; a range of otherwise identical photos which vary only in shutter
speed. Some cameras have built in support for this, but mine doesn't.
However, with the CHDK third party software, it can be added.

http://chdk.wikia.com/wiki/Main_Page

I set the shutter speed bracketing value to 1 2/3 EV, http://chdk.wikia-
.com/wiki/CHDK_firmware_usage/AllBest#Tv_bracketing_value and used
"custom" drive mode, with 5 second delay, taking 5 photographs.

This gives me a massive overall EV range, the defining property of HDR.

I then downloaded the photos to my Linux laptop (Fedora FC8)

I used the "enfuse" program to merge them; since I only wanted the saw
teeth, I cropped that part of the image from each photo to avoid
unwanted pixels influencing the HDR merge operation.

http://wiki.panotools.org/Enfuse

Since the sawteeth image is pretty much monochrome, and I was simply
trying to get a "good" exposure I used the following enfuse options:

enfuse -o output.jpg --wExposure=1.0 --wSaturation=0.1 --wContrast=0.1
--compression followed by a list of input files.

To get the side show of the teeth, I used another, more usual, tripod, a
Gitzo Tatalux Reporter,

http://groups.google.com/group/rec.photo.digital/browse_thread/thread/c-
d1f23bf89e8735a/c8f512fb34edad03 http://tinyurl.com/2ml8gq

and again used my home-brew extension for final position of the camera:

http://galootcentral.com/components/cpgalbums/userpics/10152/saw_how_lo-
w_close.jpg

All other aspects "as before".

I hope this has been of at least some interest to at least some member
of the Porch. Since many of the choices I made were driven by equipment
or facilities I happen to have, I would not expect anyone to follow what
I did in all details, but I hope it offers guidance or inspiration as to
what is possible.
