Yep, you use right wing feathers in a right wing clamp. Most clamps have some adjustment for the amount of helical. Maybe it's set for too much helical such that the entire feather isn't lying flat on the arrow shaft. If so, adjust it a little to reduce some of the helical. Also, be sure you are, in fact, using right wing feathers. If you hold a right wing feather in front of you pointing away from you, the lip should be on the left side. If it's on the right side, it's a left wing feather, and that won't work in a right wing jig. Good luck.
