If you spread open the pinches in the channel; and,
run a 6" length of windlace through the channel, spreading the channel when necessary; and,
lubricate the windlace with water soluble lubricant; and,
start the channel in two directions at an opening near the top of the door opening; then,
the job is not too bad.
That is how I did the second channel/windlace. I wasted a lot of swear words and time on the first piece of windlace, before I figured out that procedure.
