I have used this method for stretching cloth for years. While I took care of the pro tour, this is how I stretched the cloth.
I place the cloth on the slates, then using a chalk-line, [white chalk], snap two lines long ways 2" apart down the center of the bed cloth, then snap 3 lines cross ways, one at each end about 6" from the end of the slate, and one cross ways at the side pockets. This will allow you to stretch the cloth evenly by keeping the lines straight.
{{{{BYW, the reason for using two lines down the middle, is if you have several tables to do, and two or more mechanics, you can stretch the first cloth and then tell the other folks how much to stretch, by way of measuring the distance between the now stretched two lines}}}}.....All tables will play close to the same.
Now, on one end of the table, staple about 6", then go to the other end and stretch long ways, and staple about one foot, then go to the first end and stretch 4" per side of that and go to the other end and repeat untill both ends are stretched.
Now start at the side pocket and work it down to the end, go to the other side [straight across] and repeat, and then to the other ens side and repeat.
By maintaining the lines straight in both directions, the cloth wil be evenly stretched and have no, HOT SPOT, or slow spots and the balls will track straight.
Most mechanics stretch one end and then the other end. WRONG.
By stretching one end all the way across and then the other end, you NEVER get it stretched evenly, or tight on the first end..
For tools, you can purchase a couple pair of VICE-GRIPS, with wide flat plates for jaws, about 2 to 3" wide].. This works go, and allows you to really stretch the cloth...
Use a staple and make sure they are not to long, so they will come flat with the cloth and not be sticking up. They won't hold that way. Just make sure there flat after stapleing.
