OK now ,,,  I just read every post in this thread..  some very interesting stuff,  to say the least..
I have a lot of comments, but they shoot out randomly, so bear with me..
I have had a plucker for over 35 years.. It is still going strong..
I do about 200 birds a year..
I also have a less expensive model plucker..  I found that the old plcker, with the fingers spaced closer together, works much smoother with less jerking and is twice as fast and cleaner as the newer model..
I am in the process of building a modified Whizbang..  I will let you know how that turns out..
my goal is to do it for under $200.oo..
the cheapest place I found for fingers is the website for the whizbang..  the author's son resells  fingers purchased from Kent Co..  He includes shipping free in his prices and has price breaks on the number you buy..
I too have a table saw that I am going to reincarnate as a plucker..  It is a motorized delta.  I am going to remove the top and completely gut it.
Install a drum with self centering bearings mounted on opposite sides of the cabinet and driven with a wash machine motor..  I am going to line the fingers in rows and attach metal rods between the rows to form the work surface..
for a drum, I am probably going to use PVC, or else a piece of well casing or something similar.
I am running long here, but I will be back..LOL
