OK -- here it is - my project horn using staples completed. Installing the staples was not as bad as I first thought and the wall thickness of the spout end was thicker than I first thought. I drilled undersized holes and tapped the staples in. I used 0.062" diameter "bailling wire" which did a great job and was very secure in the horn & wood - no epoxy was used in the staple holes. The wood spout was a pain to attach to the spout as this was my first of this type and I tried to contour the wood hole to fit the horn spout contour. I should have rounded the horn spout to fit a round hole that I drilled into the wood spout not the other way around. The wood is epoxied onto the horn (GASP) :redface:. All things considered I think it came out OK .
