Default RE: Rubbing the block on NAP Quicktune 4000- HELP

The following is a new FAQ that they are planning on adding to the QT 4000 [NAP- Website]. I thought I'd share it FYI.
==============

Below is a troubleshooting review that will help you obtain maximum clearance and performance with the rest.

Troubleshooting

Cannot attain fletching clearance on the prong block or the prongs. This usually occurs from the rest and nock point being located too low or because of uneven nock travel.

Solution –

First determine whether the bow is a dual cam or solocam design.

Some bows both dual cam and solocam designs are susceptible to nock travel issues. While any bow can be tuned regardless of nock travel, knowing what to do in those situations can often save much time and effort during the tuning process. For solocam designs, often the simplest solution is raising the nock point on the string from 1/16” to as much as 3/8”. The arrow will no longer appear to be 90º (right angle) to the string. Instead, it will appear to be pointed slightly downward at the point. If the problem still occurs, start by removing the black prong block from the silver shaft on the rest. The 7/64 cap screw on the bottom of the block attaches the block to the shaft. Once the block is removed, each prong can be slightly extended by using a 1/16 Allen wrench to loosen and then retighten each set screw. This increases the height of the prongs slightly in the raised position. Consequently, the string nock must again be reset slightly higher to accommodate the extra height in the prongs. Depending on the bow and set up the arrow may or may not form a right angle (90º) with the string.

For a Dual Cam design first determine whether both cams roll over at the same rate by contacting a local archery pro shop and asking for assistance. If the cams do not roll over at the same rate the bow will be very difficult to tune. Once cam roll over is verified and/or corrected, the set up instructions above should solve the clearance issue. If the problem still occurs, start by removing the black prong block from the silver shaft on the rest. The 7/64 cap screw on the bottom of the block attaches the block to the shaft. Once the block is removed, each prong can be slightly extended by using a 1/16 Allen wrench to loosen and then retighten each set screw. This increases the height of the prongs slightly in the raised position. Consequently, the string nock must also be reset. The nock point will be reset slightly higher to accommodate the extra height in the prongs. At this point the arrow should be 90º (right angle) to the string. If the problem still persists, slightly raising the nock point as in the above solocam design example will solve the issue.

Cannot clear the inside hen fletch on the rest pick up cable.

Solution –

Bend the cable as it exits the pivot block. Using your finger or thumb, bend the vinyl coated metal cable over toward the cable guard. This creates a permanent set in the cable causing it to track closer toward the cable guard and further out of the way of the arrow path.

Hope this helps and good luck this season.
