sorry, Pa...I found a utube video of the process..." filling a quilt with Down"...by Hofman out door supply 3/1/2017 in the viedo you'll see the method that I used. basicly the donor down is sucked up and injected into the channel. the weight of the donor down is measured with a kitchen scale as the vacume is blowing it into the channel mentioned ( the opperator has to be careful, not to "jostle" the container sitting on top of the scale (gently encourage the down to travel towards the opening ofthe suction opening). sorry but posting a link is outside of my skill set.
