Championship 3030 stretching...

Sheldon said:
The last 9' tables I covered with 3030, I stretched 3.75" on the side and 3.75" on each end.

I couldn't do that with the 3030 green that we had, even though I was thinking of stretching the next one 3.5 side to side and 6.5 end to end, I don't know if from one batch to another it might be a little different. There the next cloth to install is a green 860, I have to find the right stretch as quickly as possible, I'm just starting to show the guy who installs the cloths in our hall how to do it, his cloths always became loose quite quickly, he didn't index anything. Apparently Simonis have changed since their flood, I have the idea to start with full stretch -5/8'' as index side to side and to see how that will close end to end.
 
I don't want to play devil's advocate, but I'm going to work with the inch index from now on and multiply it by the lengths of the slates and I think it will be perfect. I stretched my first fabric in a 1:2 ratio and see that it is a little tighter lengthwise. When you stop and look closer the lengths aren't exactly 1:2, there isn't a big difference but it's visible. If we take 3.5 inches divided by 57 = 0.061 and we X by 107 = 6.57 and not 7 inches. This is the small difference I can notice when trying to pleat the fabric with a lot of force.

If you take notice, you'll see cloth stretches more in length than it does in width.

As I already said, I'm just starting to help the guy who installed here and who wasn't indexing anything and all his fabrics were becoming very loose on the short side. I'm going to install a non-HR 860 soon and I'm going to check its elasticity to get its specific index, the boss bought 20. There is one thing that seems to me and I am convinced that it is illogic, it is to check the index of all cloths in the same way, that is to remove 3/4'' of the short side full stretch, it simply cannot work for a cloth which has double or double and a half of stretch as a simonis for which this 3/4'' was determined. Rather, it must be done in proportion for each different cloth. Let's imagine a cloth that has 6'' of full stretch lateral and remove only 3/4'' to determine its index, that would be illogical and it would not work. So given that apparently the simonis has changed since their flood, I'm going to look at it closely to see how to proceed correctly, I prefer to stretch it a little more in width for the first experimentation than a little less.
There is also one thing I notice when forcing to pleat the 3030 that I installed 3.5 x 7'' stretched, is that it is slightly tighter in length, although very tight also in width, which makes me think that the stretch of the 3030 fabric is equal on both sides

Backing off the 3/4" is to give you an approximate beginning point. Any correction to that comes when you stretch both ends, the second end stretch tells you whether you need to back off a little stretch, or add just a little more. All cloths will balance out 2 to 1, trust me.
 
Hi RKCI have been using your method of starting points with index etc for napless cloths . I have been now using this method for napped cloths{Strachan 6811} The traditional method of recovering snooker tables etc is to pin the baulk end with a few staples then the foot end with a few in the centre.then u pin side pockets then on to the corners {like a union jack shape}. However when i came across a slate with massive cut outs for side pockets i couldnt pull the corners tight enough to get wrinkles out without the cloth starting to tear around side pocket staples and it was scary. can you see any reason not to stick to your method for napped tables? would love to know what you think.

I don't staple of pin any cloth, not even Snooker cloth, so yes, glue it!
