The tails are made from 5/8" wide latigo strips that are 6ft long. I'll probably shorten these once I start fiddling with the right length for the canoe yoke. But this'll have to wait until I'm up north again before I can test it out on the boat.
For fasteners, I noted that the NW Woodsman version used brass Chicago Screws which seem sturdy enough for this project. If not, I could alway attach copper rivets but didn't have any on hand at the time. Simple work with the hole punch, a little trimming and she's good to go.

Inserting the brass Chicago Screws
Apparently there's a trick to prevent the screw fasteners from loosening - adding a bit of nail polish which dries to form a tight bond. Never thought I'd have to rummage through the wife's cosmetic bag, but it's for a good cause right?
