I recently purchased a jo-jan fletching clamp, and find it extremely easy to use with only one issue. After i seat the fletching, the clamp isn't making flush contact at the rear and this is causing my fletchings to lift up slightly at this end causing a small gap so the clue cannot bond the fletching to the arrow properly. I know this is probaly going to get moved but oh well [&:](the tech forum seems pretty dead...)

If it matters, I am using 2'' quickspins with bohning fletching glue

2x things you can do. First of all, don't put the fletch the whole way into the clamp. Leave 1/8" between the base of the vane, and the clamp. When you put the clamp on, push down evening out the surface.

Also, you can fold up a piece of paper and put it like a shim between the top of the clamp and the shaft. This will even things out nicely.

One issue I have had, especially with smaller diameter arrows is not getting the nock pushed into the jig receiver all the way, it slides into a V and if you don't push it in all the way the arrow isn't centered and you could have this problem.

I have also used the leave it out of the clamp a bit, just be carefull and get it even or you can end up with the vane not having consistent contact in the middle.

The real way to fix this is to readjust the jig to your shaft. The screws in the front and rear of the jig allow you to adjust the offset of the shaft in relation to the clamp. Put and arrow in and set a clamped flething on it then adjust the jig back and forth until you get 100% contact between the fletching and shaft. If you're having to shim things and monkey around with not setting the fletch all the way into the clamp, something is out of adjustment. I have to readjust mine every time I switch to a different shaft diameter but I've never had issues fletching anyhting from a 2512 aluminum all the way down to a Superslim A/C or uncut flu-flu's down to Blazers. Play with it a bit and you'll get her figured out.
