It don't mean a thing if it ain't got that ping.
I don't know the known one, but RKC explains the stretch index in this video. It can be used to figure out how much stretch index if you don't get an answer. He goes through the math of it. Hopefully somebody has done it, I've only done 860 and 860HR, no idea on the 3030.
Oh, if anyone can give me some advice that would be great!
Which is why you need to back off on the side to side stretch, and move it to the end to end.
I'll give you an example. I installed the 3030 on a Valley 7ft bar table a little while back, I stretched the side to side 2" which allowed me to stretch it end to end by 2" at both ends. Because I stretched it 4" overall in length, that made up for the side to side stretch, making it even tighter. So, the 7ft slate is 43" wide, 2"÷43" gives you a .04651 inches of stretch per inch. A 9ft slate is 57" wide, so 57"×.04651= 2.65" or about 2 9/16" stretch side to side and 2 9/16" stretch at both ends. When you stretch the hell out of it side to side, then try stretching it end to end, the end to end stretch always loosen up, but not the side to side, because the stretch isn't balanced!!
Good Thank You for this answer RKC, I understand very well what you have just explained there, but it is to find the right index to be able to stretch it equally in both directions and that they are well stretched everywhere, if you leave with less or more stretch on the side the work will not be optimal, very happy with your help and thank you again!!
The goal is for the cloth to be stretched equally in both directions and at the same time stretched like a guitar string, but without knowing any measurements it can take quite a bit longer to achieve the right result, Thanks Professor!!
If you're doing multiple tables, then your first table is your find the stretch table. What ever your side to side stretch is, it must be matched at both ends. But it's based on the second end if you need to make a change in your side to side stretch. Example is, when stretching the second end, let's say you can stretch the cloth a 1/2" more than you marked it out to. OK, second table, add an 1/8" to the side to side stretch, then add an 1/8" to both ends and judge out the second end stretch finishes up. If it's perfect, then take that stretch index, divide it by the width of the slate, then you'll know exactly how much the cloth will stretch per inch. Keep that number handy, then regardless of the size of the slate you're doing, all you have to do is take the width of the slate X the per inch stretch, and there's your stretch index for that size table. Not everyone has the same strength to stretch the cloth, so the stretch index will vary from mechanic to mechanic, but the cloth will still be stretched proportionately.
In fact this is a first cloth for testing purposes but if the results are good we will probably order 1 or 2 rolls, so I will go with your index measurement and take notes as you say on what this gives the stretching of the second long side or the total stretching of the long side and we can adjust if necessary. Thanks for the help RKC!
Oh yes, I installed our first Championship 3030 today on a 9 foot table. Having had information from different mechanical installers, I went there with my feeling according to this information. I stretched 3.5'' on the short side and 7'' on the long side and believe me it was really the maximum we could stretch it, 2 guys with vise grip metal sheet clamp and it took a lot of force . The question I ask myself now, are we stretching it too much?
I don't know if you are familiar with the 3030 cloth, but I couldn't have stretched the 3030 that we had any more than we did. I went with 3.5 inch lateral without knowing what it would look like on the long side, we marked the cloth at both ends at 3.5 inch and it was very difficult to close the last end, the staples wanted to go through and tear the cloth . We could have gone with 4 inch lateral but we would have had less than 3.5 at each end, we are 2 very solid guys we don't lack strength. The only thing for a first is that we had a little difficulty with our anchor points on each side of the side pockets, the staples did not hold or tore the fabric to get full stretch up to the pockets. corners, the next installation I will clamp the cloth to the side pocket while I staple it to the corner. I put a couple of photos, there is a lack of lighting along the rails but there doesn't seem to be any shading, what do you think? And don't forget, English is not my familiar language
He didnt not say that you should have stretched it more, he said that you should have stretched it less.I don't know if you are familiar with the 3030 cloth, but I couldn't have stretched the 3030 that we had any more than we did.

Ah ok, I thought he said the opposite, Thank You!
''That's a little light for a 9' though.'' that means too much??
I see, so it looks like you could have stretched more lengthwise but less widthwise.
Maybe Sheldon will tell us what he meant by this message! And to come back to the installation, I believe that those who stretch almost 4 inches on the width, do not measure the 4 inches each end and they close the ends to the feeling, this quit is less of 4 inch , I believe.
