Dents in the felt

I believe 15 is also a joke.

2 sticks and a rock would do the same thing, no?

Sure, if you have the patience to fiddle with them to ensure the sticks are square to the rail (so the roll starts straight) and they to not move. Chop sticks have a purpose but that purpose isn't doubling as a stimpmeter. I'm all for multi-taskers but sometimes the purpose built tool is the best tool for the job.

Wow, I didn't know expensive levels could eventually "drift" out of level and eventually be worthless! Have you ever heard the term "calibration"?
Have you ever heard the words "slate grinding marks"? To respond any more to your post would be like lowering my intelligence to that of 3rd grader!

If they never drift then why do they need to be calibrated. Don't take every post about putting a table together as some challenge to your expertise.

You know they require calibration and so do I. Pool table mechanics aren't the only people who use precision levels and other instruments so don't assume you are also an expert on instrument calibration. It was just a simple suggestion that maybe rolling a pool ball might be a good way to confirm how a pool ball will roll.

For those of you who remember the amazing curving cue ball at the end of one of John Schmidt's runs, that's the one on the ramp with the metal track. A few billiard books in the background.

I don't know why it wouldn't be valuable to roll balls on the bare slate. It will pick up any tiny steps at the slate joints and any slight roll off that would be masked by cloth. Of course fancy levels are the gold standard but they eventually drift out of calibration and are only able to tell the story of the area they are placed.

I rolled balls for hours when I did my own table because I didn't have multiple known levels. It took me a long time but so what, I do one table every 5 years. I built a little "stimpmeter" type ramp to roll without spin...not as fancy but similar to Dr. Dave's shown below.

Again, if you have a bunch of precision levels...great. If not or if you just want a double check then what could possibly be more definite than slow rolling balls?

When I put the cloth on my Gold Crown I tried slow rolling balls on the bare slate, I could never get an accurate reading though, the ball would stop and roll back towards me so I gave up. :)

What do you mean by 'dropping on edge of cushion'?? Other than tapping the head ball on the spot to set it i've never heard of dents in the cloth. Sounds like old pool lore to me.

You can check how a table rolls by dropping a ball on the edge of the short rail so when it rolls to the other end rail and back it will give you feedback as to how the table rolls Doing it this way you won't add unwanted spin on the ball. Try it.

If you hold the cue ball up very high and miss the nose of the cushion and hit the table directly, then yes, you could dent the felt. But you have to hold it like 10 feet up. When you hit the nose of the cushion on the way down, the cue ball is deflected nearly parallel to the table and it's like dropping it from a few inches. It's not a problem and it's the way table installers have checked for straight roll for decades if not centuries.

Thank you Bob for that answer. I agree completely, like I wrote in my post there is a person at one of the local bars telling me that method causes dents in the felt. I told him he was full of it and I would try to find for him some proof that it didn't have any adverse affect on the felt. If you have anything I could print and show him I would appreciate it.

Why do you keep answering then?? BTW, i've seen tables re-done by some of the best in the biz. NOT ONE ever did this. If the tech knows how to use a mach. level he shouldn't have to roll any balls. I've watched the Diamond factory guys set up a Pro and it was dead perfect when they got done. No ball rolling of any kind.

You have gotten WAY off the subject. It's not about how the ball rolls, it's about if dropping a ball on the edge of the cushion causes a Dent in the felt. Thanks for your comments anyway.
 
WOW!! You all went way off of what I was asking, DENTS in the felt. How anyone checks if a table rolls true is not the question here. Anyone that has played pool knows that their are many, many tables that roll off. And they might be level. We all can't play on the best equipment. Their are many ways to verify if a table rolls true. Using them helps with getting a table as good as you can. So if anyone can post to me proof either way that dropping a ball on a table will produce a dent in the felt. And I'm only talking about less than 6" from the surface. Thank you.

Go with your buddy to a pool hall and perform said test. The proof will be right before his eyes.

I suspect the buddy will not accept anything anyone here says. Printed or not. Whether he will accept the results of a test is up for grabs.
