When I'm fletching there is never a rush to get the job done. I've been using a water based super glue that takes forever to set but never fails. I set the clamp and find something else to work on, I call it multitasking. For the life of me I can't understand why any of you could be in such a hurry.
If I'm working with bamboo or cane I can always find another shaft to file a nock, straighten, or another project on the workbench. Life's too short to push the envelope and ruin good feathers.
Why rush the final stage of such a rewarding project.
