SnowDude;
Greetings from Arizona, formerly from Olympia.
I do my splices differently and have had good luck with them. Long story less long, I mark my fletching clamp where I want my splices and add the feather sections that I cut. These are uncut feathers that I later burn.
The leading edge of the first section is cut (Fiskars fine point scissors) at an angle. I then apply slight pressure to the clamp and slide it into the clamp up to my first mark. I then cut the rear of the first splice at the next mark on the clamp. This & the rest of the cuts are made straight across the base and at the same angle of the vanes. The following splices are added following the marks on the clamp. Slight pressure to open the clamp and slide the sections in, rear toward the front. Since I put a small crest under the fletching that matches the larger main crest, a couple of the splices are only about three of the vane lines in length. When I have my fletch assembled, I check to make sure that everything is nice and snug and glue it up. When I remove it from the jig, I run a thin bead of glue along each side of the length of the base.
Clear as mud, I know, but it's really pretty simple. Just time consuming when I make five splices per feather, but anything worth doing is worth over-doing !!!!
