I use this tool, it works much better than an angle finder made with 2 thin flat blades. I put the thickest part where the reader is located on the nose of the cushion so that the thin blade is in the angle

It don't mean a thing if it ain't got that ping.
I have a similar one I bought at Harbor Freight for really cheap, it doesn't look near as nice as that one though. I wouldn't go build a spaceship with it but it's pretty accurate against known standards.
Haha, no spaceship, there are already 2 astronauts stuck in space for another 6 months minimum because of their spaceship. The model that I show is very precise, it is within tenth of a degree, the company mentions less precision but it has a very good one, by checking it with machinist's squares I can see it easily.
Thanks, but what I'm asking is what is the correct way to measure, and when Diamond says theirs are 141 deg, how is that measured? There are two ways to measure, and they are apx 1 deg different. Also with the tools I have, my best case neasurement is still more than 141 deg.
I have been told diamond uses a fixed angle for all tables and it is the same 141 degree.
Measuring as you state with the base on the front cushion edge and blade up an 1/8"-3/16" in the back edge, basically the top edge of the angled portion of the cushion, I get 144 deg. Diamond and cobra say thats impossible, but I am very mechanically inclined and have a large shop full of tools, and quite honestly it's quite simple to measure. Also my pocket points are straight and not rounded in making it easy to measure also. So what I really want to know at this time is where is Diamond basing there measurements off of, there is a good degree difference from up a 1/8"-3/16" vs parallel with the front edge. As it stands now my best case sinerio is about 2 degree more than their stated angle, which if true, would explain why my table rattles balls more than other Diamonds I play on.
I will go out in the shop tomorrow to see if I have a better angle gauge, or may go buy one, they can't be that expensive, but honestly, I don't think what I have is off over 2 degrees.

Went out to the shop and got another protractor to try. Also cut a perfect 45 on a piece of wood with my chop saw and both protractors read exactly 45.
So the measurements I got are 144 deg on the top edge and 143 parallel with the front rail edge, and about 1/8"-3/16 down apx 2" twords the back. How is this possible if Diamond only cuts to 141 deg?
It's tough holding for a photo, but I'll get my wife to shoot a picture if needed.

You measure correctly, and 2 to 3 degrees each side of the pocket is a lot, it makes a very big difference in the pocketing balls. Has your table been retouched since it left the factory, also reality and what can be said can be 2 different things, we see this regularly. Now you know why your table plays differently.
Hasn't been touched other than some tweaking of the leveling wedges since delivery at the start of covid. It's a fantastic table. It is easier to pocket down the rail shots on other diamond tables, even with their pockets being 1/4" smaller. You just have to be more carefull of how hard and what english you are using more so on mine.

Rattler angles
I guess I just need to get better at my shooting. They do go in if shot right.
Good table for practice!!
Sort of funny actually as Diamond uses my table picture in their web page as a representation for their Professional table version.
As I said, I actually really do like my table but am really interested in knowing how my pocket angle differs from what all other Diamonds are supposed to be. I'll know shortly if it is just my measuring or what as league starts in a couple weeks and I'm going to bring my protractor along to see if it's just my measuring, or my table. I should have been thinking Friday night as my wife shot a small tournament there and I went along to watch. Could've measured it then. No biggie, I'll know in a couple weeks. Probably just me.

Yeah, but they spit out balls that should have went in.
Line 4 balls frozen together on the rail just past the side pocket. Hit the cue ball near break speed into the first ball. Does the 4th ball pocket cleanly or does it rattle?
May try that later, but honestly that wouldn't mean anything to me. I'm not saying that balls don't go in if hit correctly for my table, I am saying though that I seem to get less rattle when playing on other Diamond tables even though those tables pockets are 1/4" smaller. What does matter to me is why my pocket angles appear to be different than other Diamond pocket angles when they are all supposed to be the same. Mine might be the same, but don't appear to be with the two protractors that I have, and those protractors check out to be exact when measuring a test 45 deg cut with my high end 12" chop saw. Like I said, I'll know more when I get a chance to measure the Diamond tables at where we play our Monday night league at. They may measure the same as mine at home, maybe, but I doubt it, but maybe.
The only thing I am trying to find out now is how does Diamond say the angle should be measured and so far, there is no answer to that.
On the top edge, there is a apx 1 deg difference when compared to parallel to the cushion point centerline. With the protractors I have, I am seeing 144 on the top edge, and 143 deg parallel to the cushion point. It is a little harder to measure parallel to the point centerline so it is possible I could be off up to 1 deg, but not 2.
This is all for now as we are just going back and forth and until I hear how Diamond feels it should be measured, or get a chance to compare another diamond, there really is not much more to say. Maybe they are actually the same, I won't know that for a couple weeks though. It is a little harder to measure parallel to the point centerline.
The test will determine if you have rattle angles. Hard hit balls down the rail should drop if the pockets are cut properly.
Yes that shot will drop as I expected it would. Still want to find out if and why my angles are possibly different and where to measure. Will know in a couple weeks I guess. Maybe later this week also as I am going to our summer place, and one of the bars there has a Diamond table. May be too crowded there this week though.
It's a dead ball.
Spinning balls and balls brushing the side rail can be unjustly rattled.
If the opening angles are indeed closer to 143*, it's off-specs.
I'll let you all know in a few weeks if it is just my measuring, or actually my rail cut. Really hard to believe my cut is that far off.
Almost was able to check our league Diamond tables tonight as I just got word there is a pre league meeting tonight, but then I was told the tables are in pieces as he is having them recovered for the start of leagues. We really have some good leagues and both will recover their tables at the start of fall leagues.

It's not. If the pockets are cut too wide, the ball will rattle.
