Does anyone have any pictures of a homemade feather processing jig.  I just looked at the one on 3Rivers and I am not willing to spend that much money on something I should be able to make.  I have done some feather by hand sanding, but I have a lot of feathers to process and am looking for a little bit quicker way to grind the quills down.  Any pictures or instructions would be very appreciated.
Thanks,
Mike
