 
  Finishing Wild Turkey Feathers
  You have managed to acquire a batch of nice wild turkey primary
  wing feathers, now what? You really have two options, do them
  yourself or send them to someone and pay to have them done. Personally,
  I do the latter, but I will describe a method to finish them
  yourself if you are so inclined.
  If you do prefer to send them off and have them professionally
  done a good place to send them is Trueflight Feathers. They will
  grind the bases of the feathers and return the full-length feathers
  to you for $15 per 100. They will only do this work during their
  slow time which is November  December. I have been very
  pleased with the quality of the work that they have done and
  they are pretty prompt with their service. Their address is P.O.

  Splitting the quills and finishing the bases isnt really
  very hard to do. To start with you need to split the quill. I
  have found that using a new (very sharp) single edge razor works
  quite well. The primary wing feather has a trough that runs the
  length of the feather. This trough is very prominent at the base
  of the feather and fades out towards the end. Get a piece of
  plywood or particleboard to work on. Use something that you dont
  mind scratching up. Push the razor through the middle of the
  feather near the base end. (See photo on top). Push the corner
  of the razor into the board so that it is secure. Keeping the
  razor in place pull the feather through the razor splitting the
  feather as you go. Use a slow steady speed.
  Trim the ends of the feather off to the desired length that
  you want, i.e. 5.5". You are now ready to sand down the
  quill to desired thickness. It helps to look at a finished feather
  to get an idea of what you are trying to achieve. There are two
  ways to sand down the quill, either by hand or with a power belt
  sander. If you are going to do a lot of feathers then you will
  probably want to get proficient with the belt sander. Put the
  feather into a straight clamp. If you dont have a commercial
  straight clamp you can make one using a couple of metal strips
  and some binder clips that you can buy in any office supply store.
  Using medium grade sandpaper and a sanding block sand down the
  quill to about 1/16" thickness. This takes a little practice,
  particularly keeping the plane of the quill surface perpendicular
  to the feather. (See photo #2). The belt sander does it a lot
  faster. You just have to be a little careful not to sand off
  too much.
   
   
  When you have completed the sanding you will probably have
  a base that is a little wide for your taste. To trim the width
  of the base, use a sharp single-edged razor and a metal straight
  edge to trim it down. Now you can fletch and use a feather burner,
  or use a chopper to cut the feather to its desired shape.
  I like using turkey feathers for my hunting arrows. They seem
  to be a little more sturdy than the commercial feathers and they
  have more oil that makes them stand up better in wet conditions.
  The only drawback is also what makes them so desirable 
  their color. Natural barred feathers are hard to see in flight.
  To get the best of both worlds, try splicing a bright color into
  the back 1.5" or so of each feather. So where do you get
  these feathers? The best advice that I can give is to let everyone,
  particularly shotgun turkey hunters, know that you want them.
  You would be surprised at how many turkey wings get thrown away
  each year. If you have some that you dont want, give me
  a call, Ill gladly take them off of your hands.
