Summarized Instructions for Bowling Training Tools

If you have already received a product offered from our online store or are wanting to get one and have queries on how to use it properly, please reference this article. The four main products that Ten Pin Doctors currently offers are a release trainer, laser targeting tool, bowling ball storage rack, and quarter scale. Here is a comprehensive list of instructions on how to assemble each product (if necessary) and how to properly use them.

Release Trainer

If you receive a rev trainer and one of the wheel bearings pops out, which may happen when rolling the ball on it, simply know that doesn't mean your trainer has broken. Get a hotglue gun and hotglue the bearing(s) back in. The bearings are hotglued on prior to shipping, but will obviously lose adhesiveness over time.

To see a simple "demo" video of JR using the rev trainer, please refer to this video:

So, using a rev trainer is pretty simple. Place the ball on top of the bearings that are placed inside the concave area that resembles the shape of a bowling ball. From there, spin the ball on the wheel bearings to work on both your release and rev rate. If you have a problem with the bowling ball's thumbhole constantly getting stuck in a bearing on each release, that's because you're rolling the ball almost completely forward, or end-over-end. Add just a little more side rotation to your release, and the thumbhole won't get stuck in a bearing each time. You can reference the arrows on the sides of the rev trainer to work on different amounts of side roll or axis rotation.

In addition to working on different types of releases, you can always work on rev rate by focusing on clearing out your thumb much sooner than when rotating with the fingers, keeping your fingers below the equator of the ball, and rolling (not throwing) the ball with the fingers as you uncup your wrist from its previously cupped position.

Laser Targeting Tool

The laser targeting tool shines two laser beams down on a lane to help you visualize three key components in your game: (1) targeting, (2) footwork, and (3) armswing. For targeting, have the laser shoot down the lane at a certain angle and passing a certain board at the arrows you want to play. That way, it will help you visualize your intended target and the proper launch angle through the front part of the lane. Since the laser goes about 35 feet, you can even see if you hit your intended breakpoint. For footwork, you can do a cross heir before the foul line to see where you need to end your slide step, whether closer or further away from the foul line. Lastly, you can point the lasers at a certain trajectory on the approach to help guide your swing plane in a certain direction, whether playing straight from the outside part of the lane or playing inside and steepening your angles.

Simply twist either of the two end caps on the lasers to adjust how the laser lines intersect and at what angles. You can twist them to create a cross heir or simply have them run parallel to each other. For a full instructional video on the Xtreme double laser by JR, simply reference this video:

Four batteries are used to charge this device; two for each laser. Since these lasers require a lot of power to operate, batteries tend to die after 30 to 45 minutes of usage. So if you receive an Xtreme laser without a pack of 8 rechargeable batteries and a charging dock, you can get one here: 8 EBL Rechargeable AAA Batteries with Battery Charger.

For the laser targeting tool, you will need a tripod to hold the laser high enough to where it can angle down towards the lane. Tripods are not included or shipped in the purchases for the laser devices, so they will have to be bought separately. A good choice is a Joby tripod which goes up to 5 and a half feet tall, available at this link: JOBY RangePod Smart Tripod (Black).

If you received an Xtreme double laser without metal threads in the bottom casing, then the tripod attachment can quickly get loose when trying to screw into the threads engraved into the plastic itself. So, you can purchase adapter screws designed specifically for threading into the case here: 10 Pieces of 1/4" Female to 3/8" Male Adapter Screws - Brass Nut for Tripod Heads. From there, use a soldering iron to get the adapter screw hot, and then press the case against the screw on a flat surface so it can penetrate through and make threads.

Bowling Ball Storage Rack

Please refer to the below video for instructions on how to assemble an 8- or 12-ball rack.

Quarter Scale

Please reference the video below on the proper way to measure a bowling ball using a quarter scale:

In recap, the 8-step process for determing a bowling ball's layout is as follows:

1. Find the center of the grip.
2. Draw a line to your PAP.
3. Mark the VAL line from the horizontal axis point.
4. Draw from the pin through the mass bias, for asymmetrical balls, or the CG, for symmetrical balls.
5. Draw a line from the pin to PAP.
6. Line up the quarter scale with the zero over the pin and so that the scale crosses the mass bias or CG. From there, you will find the amount of degrees for the first angle, or drilling angle.
7. Measure the distance from the pin to the PAP.
8. Place the zero on the PAP and see how many degrees it is where the scale intersects the line to the pin. This is the third angle, also called the VAL angle.
