Their carbon fiber shafts are phenomenal. Market leader.

I don’t really think that this concept solves a problem that needs to be solved. People don’t have trouble telling which side of the pocket that they missed on. This is also a product that has been invented and reinvented over and over again for 50 years. It isn’t novel. So don’t sweat it.

The definition here of COR (COF was a typo) can only be defined as what is shown at 0:30s of HSV B.15 video mentioned above. If you really wanted to, you could measure the slope of the increasing spin after impact and use that as your cloth friction coefficient. Then do the math and back...

Though not the intended purpose of the DigiBall, Dr. Dave's recent post, which included a high speed video of a ball rebounding off of a rail, gave me the idea to try to measure it directly. Here is his video: Dr. Dave measured the incoming velocity and rebound velocity of the ball by...

Don’t write off FedEx completely. I have only had success with FedEx and DHL for international shipping. All other carriers were consistently a headache and many months of delays. Especially UPS. For intranational it is a bit different.

The idea is to fill the holes with retractable steel rods, that create divots to place the balls, and then go flush immediately after breaking. The problem is that the 90 degree sharp edges between the slate surface and hole inner diameter will wear out the cloth at those points, as you pointed...

Yes. This is what this filter system does, especially the odor. The OP asked for a product solution, and this is a tangible product solution.

Buy a RabbitAir purifier for your apartment. My father had the same problem with a smoking neighbor and it worked for him. I have bought two of them also just to keep my air clean. Replace the filters once per year. https://a.co/d/065qjrGv

Does anyone want to drill holes in their slate and try my disappearing template idea?

Someone asked that I add the feature that beeps every 10 seconds. I thought it would be annoying but it turns out to be very useful. It actually helps me slow down and take more time, reminding me that I always have at least 10 seconds to stand there and think. I had a habit of shooting too...

I posted these earlier in the Main Forum. Though I mostly had carom in mind... if you didn't see it already

@El Toro I understand how you are feeling. Emotionally separating yourself from your ideas is a learned skill. Like anything else it is something that you have to practice and get better at over time. I know all too well. Everybody in the world has great ideas from their own perspective. Ideas...

I see what you mean.

The title of the thread is “drills”. What drills can we do that help improve alignment. Just because you don’t need drills anymore doesn’t mean other people can’t benefit from them.

Much better
