I'm getting ready to attempt my first bamboo spey rod, a 12'er. I am looking for specific instructions on the spliced joints. Other than needing to add to my final dimensions some, I can't find much info on the subject. Info like the angle/length of joint, locations, orientations/which flats, etc. would be greatly appreciated. Is this info available somewhere? I've read some of Garrison and some of Gould. Cattanach says he makes them so the scarf starts on the top flat and finish on the bottom when doing repairs. Does that work for 12'ers too? I asked on the rodbuildingforum and didn't get much help. Anyone in the know overhere? Thanks!
