    Donny Mills is a Runout Machine - Videos Included

    First of all, thanks for posting the videos! I look forward to seeing the rest. You can get an immediate increase in power on your break by not elevating you cue so much. You're wasting alot of energy putting the CB in the air like that. Also, you may find it easier to get more power with a...

    Dealing with glasses?

    I also have small glasses, and I didn't want to have to rely on a special pair to play if I didn't have to. I'm legally blind without them and have slight astigmatism, but I'm lucky to have 20/15 vision when corrected (occasionally making out the 20/10 line). I'm a candidate for the surgery and...

    measuring a lag

    Go to the dollar store and buy a tailor's measuring tape to keep in your case. They fold up easily to a small size, but you can cut it down even smaller to the length of whatever you think the longest lag you'll care about measuring. There's no reason to endure all of the ridiculous shenanigans...

    Do you factor in a leave in event you miss this type of shot?

    There are several safety options in this kind of situation depending on the exact position of the balls, and frequently they can be higher percentage than the bank (especially on a tough table). But if you're going to take the bank - a good choice in the diagram on a reasonable table - then I...

    Should there be a new aiming sub forum?

    In the meantime, it's easy to use Google to search this site (or any other, for that matter). Just add site:forums.azbilliards.com to your regular Google search, and it will only show results across the forums. Here's a sample search for 9BallMarksman in all AZ forums as you would type it into...

    Half Ball and CTE..Whats Different?

    That's what I suspected, and our diagrams help make the distinction clear. Something about 1000 words and all that... :) To get a more quantitative feel for the 1/2-ball cut angle error between measuring from a line through the OB center vs the edge, here's a rule of thumb: There's about a 5...

    Half Ball and CTE..Whats Different?

    Here's a picture showing several CB locations along the same aiming line just to make sure we're all talking about the same thing. Energy is directed along the aim line even when they are frozen. Robert

    Half Ball and CTE..Whats Different?

    I have to disagree about there being no cut angle when they are frozen. By using your reasoning, NO shot would ever have a cut angle! That's because every shot involves the CB getting progressively closer to the OB until it results in the moment when the CB and OB are frozen. What's different in...

    Half Ball and CTE..Whats Different?

    Aiming the center of the CB at the edge of the OB gives a 30 degree cut (ignoring friction) relative to the aim line at all distances. The CB-OB distance doesn't matter - it's even true if the CB and OB are frozen. If you think CB-OB distance does matter, then you're probably making the mistake...

    Should there be a new aiming sub forum?

    It sure seems like those that claim to dislike reading aiming threads sure know a lot about what goes on in them. Robert

    Thin Cut Shots

    The physics of knuckleballs and gun barrel rifling are irrelevant as far as pool is concerned because air resistance is negligible for smooth spheres at any billiard game velocities. Knuckleballs rely on the fact that baseballs have stitches that cause asymmetrical drag when a non-spinning...

    Accuracy of the Long Straight-in Shot

    Imaging a line on the equator is a good way to visualize the range of contact points and how it changes with cut angle. If you draw a line on the ball, it'll appear longest for a straight shot and appear to shorten as you increase the cut angle by moving around the side. You're unlikely to move...

    Accuracy of the Long Straight-in Shot

    I must've misunderstood your intent then. Here's the confusing part: You're using the words "margin of error" in a different sense there, since the shot margin of error - i.e. the angular distance to the left or right of the target center that still makes the shot from the shooting direction -...

    Accuracy of the Long Straight-in Shot

    That's a common misconception, but increasing the cut angle for a shot actually decreases its margin of error. Thinner cuts are geometrically more difficult (psychology is another matter!) Margin of error is based on hitting to the right or left of your target by a certain distance. Yes, the...

    Accuracy of the Long Straight-in Shot

    Measuring between the centers without considering caliber isn't useful for this comparison. What you're interested in is whether the bullet touches the dime, and that certainly depends on the caliber! That's why Hu said this in a previous post: I compared the angular arc for both shots, and a...

    Accuracy of the Long Straight-in Shot

    One way to think about the question is to ask what diameter would the bullet have to be for the rifle shot to have the same margin of error as the pool shot. I won't bore you with the details, but I did a quick calculation that assumed a 9' table with 4.5" pockets. For the same margin of error...

    Live Streaming AFTER Tacoma

    I'm not sure what you mean by this. The only thing Jan Carl adds to the videos during editing is on-screen scoreboards and begin/end titles. All camera switching and telestration is done live for CaromTV matches, which is why his live streaming during tournaments looks just like the videos...

    Please Help with this 2-Ball Pattern

    Where did he say this? In your post where you quote him, he says (in the context of shooting when not being confident with his draw stroke): That doesn't sound like a "pinch" of draw to me. "4:30" o'clock (between 4 and 5) would be equal amounts of draw and sidespin, which matches his...

    Lost my interest and am bored when I play...anyone else feel like that?

    Not sure where you are in IA, but this room search at USBA.net shows known tables for that state. John Jacobson (member jjacobson) is in Marshalltown with a heated table, and author Bob Byrne is in Dubuque. Contact info for both is listed on that search page. Maybe they're too far for regular...
