Its funny this is brought up. I just started shooting the Bohning Blazer vanes and had a rough time getting them to stick. I also started using Loc Tite super glue gel. This was a tip I picked up over on Archery Talk. But the vanes didn't stick well at all.
My procedure in the past was this: Scape all of the old glue off. Lightly rough sand the shaft with 400 sandpaper, clean the shaft with denatured alchohol and then fletch. I never ever had a problem when I did this. The vanes always came off in peices when I tried to remove them.
But the Blazers are giving my a pickle of a time. But I think I have it figured out. Even though I was using a super glue, I wasn't leaving them in the clamp long enough. I also started to clean the base of the vane as well.
So far so good.
The dentured alchohol is cheap. You can get a big a@# can of it at walmart for a couple dollars in the hardware section.
