Quote:Thanks Siguy. It is the first time I have made a sling big enough for tennis balls. Normally I stick to stones, but in recent months slinging stones has proved a little dangerous.
The cord is some I bought from a yacht chandlers which just happens to be around the corner. It is some form of synthetic braid about 2mm in diameter with no core, and very little stretch. The rubber ball does not get the distance of stones, but it is much safer, especially for teaching beginners!

Excellent work, Coops! And thank you for the technical information.
Since I started reading Slinging.org I've found that everytime I go to the hardware store I look through the cordage section for anything that may prove useful. Next time I will look for some of this 2mm stuff or something similar. Although your knotwork may not be up to Willeke's standards, it looks great to me! .......Dan
