I have been to 2 shops in the last 3 days and unable to get vane clearence. The first problem was that the fork on the rest is leaving marks on both left and right vanes on the bottom of this vane. So I had the noc point raised another 1/16th and a taller fork that came with it and it fixed that problem but created a whole new one. Now the cock vane (UP) is hitting the bar over the rest and also as the arrow flies through the shelf the left fork is leaving black marks on top part of the left vane. The 2nd shop thinks maybe the rest is bouncing back up as the arrow comes through which I doubt. It appears when the vane reaches the rest that the left fork might be folding the vane a little bit and leaving the black mark near the edge. Any thoughts you guys as I am going nuts and I would greatly apprieciate it. The first shop says that with most guys as long as they are shooting good groups who cares. Well I care thanks to the net and learning more of the tech side. Thanks, T P.S. We also tried adjusting the rest to drop faster. *Limb Saver DZ 32 bow* I do not have the camo felt that is shown in the following pic:
Here is an example of where it is leaving marks with blazer and flash vanes. With the flash one their will be a cock vane straight up so it just does not make sense with a QAD. I put black removable marker on the rest to see where it was hitting.
Turn your vanes. Nothing says you have to have one straight up. I have the same rest and my vanes are turned cockeyed.
If looking at your arrow from behind (like you were drawing your bow) have it sticking straight out to the left (assuming your right handed) and the 2 orange vanes to the right at diagonals.
If that doesn't work, there may be something wrong with the installation. There is a thing that I've seen a lot of people missing when setting these up correctly.
It might be possible that the 2nd shop could be right??? I am getting ready to buy a QAD and I'm geting the HD model. The LD and the HD are the only models,I think, that will "lock" down and not bounce back up. I could be very wrong though...just a thought.
He did mention that he had models that do lock and I admit caught me off guard mentioning this to me. I will be talking to the QAD tech this coming Monday and run it by him. T
How did you adjust the rest to drop faster? I had the same problem and took it back to the shop where I bought it and the adjustment was in the cord back to the cables. Is that what your shop did?
I just installed the QAD Ultra-rest on my new Monster, and I'm shooting 4" FEATHERS at a very high velocity (est. 315fps), and I have no noticable fletching clearance at all. Maybe, just maybe, the vanes are just not as forgiving as the feathers are.? However, I am a bias feathers shooter just because of one of the reasons you are complaining about. I'm sure the shops made sure that the rest release string is taught at full draw. Plus, my shop tech told me that the arrow should almost appear to be angled high at the resting state. This is just a statement and I have no science to back it up. However, the rooster should be down. And, if you are having rooster clearance issues-do not change your rooster position. Paper tune and re-group. Then re-check clearance. Good luck my friend!--Keep us updated!
As far as timing, is the rest rising in last 0.5 - 0.75 inch of arrow draw? I believe this is what you want. 1 -1.5 inch is still too early. The blazers are more difficult to clear. You could switch to 4" vanes and probably cure the clearance but this is treating the symptom not the sickness. You should be able to solve this with timing. If not, suspect bounce back. What did the tech say?
If you in fact do have the LD model which is what you have pictured "bounce back" is the problem. From the picture of the marker on the bottom of the vane I can almost guarantee it. Also, as kwilson has already pointed out you want the rest coming to the full draw position in that last 1/2" to 3/4". As far as the "cock" vane hitting the retaining bar on the top of the rest you can get rid of it with a pair of pliers. You won't be able to turn your bow upside down but you can turn it to at least the horizontal position and probably a bit farther. Might be the easiest solution. Dan
