jax - that's pretty much my point - the vast majority of people have no knowlege of the sling. And until there is a publicly accessible form of the sport - they never will.
I think I've explained this seven ways to sunday in as many one syllable words as I can thinik of over the last 6 years.
I've decided on oatarget, pouch and ammo - until something better comes along. So I'm - personally - done in that respect.
Aussie.
I guess about half - 2/3 of an inch incision. The rubber on squash balls is very thick, so you need something that is long enough to give you a small hole when you squish the cut.
I filled it with a piece of paper rolled into a funnel and sand from the big pile at the golfcourse meant for the bunkers.
I selaed it with some new glue stuff that I got from poundland. It sets to form a flexible, transparent rubber seal. I used enough so that the rubber seal is on both the inside and outside of the incision.
You need to leave it a couple of days for the rubber to completely set.
Haven't slung these yet but I can squeeze them as hard as I like and the seal just flexes.
Hang on I'll go sling one at the wall a few times....
Holy crap that's a good seal !
Well about 20 hard throws at a brick wall from about 8 feet. It just about rolls back to my feet.
The seal is untouched and actually looks more durable than the rubber itself.
Got a little worried when it was covered in sand - but turned out that was just mortar I was knocking out from between the bricks
Fantastic ammo to sling as well.
So yeah I'm happy with that.
Given that target slinging is always low power and arced, these balls will most probably last for ever - or until lost.
The glue type is: 3-trimethoxysilyl propyl ethylene diamine. It has a common name that is used in different brands of the same stuff. That I can't remember as it's not used on the tube itself and I binned the packaging a while ago.
Found some on ebay - the words to look out for are: MS Polymer glue. (probably the methoxysilyl part)
Quote:Fantastic Elastic Flexible Glue
Produces a unique flexible bond and seal
Can be used on metal, glass, ceramics, mirror, plastics, wood, leather, vinyl and fabrics
Uses MS Polymer technology to create a flexible bond
Highly resistant to shock impact, water and extreme temperatures
But that small tube would be sufficient for about 20-30 squash balls. next time I spot it in a pound shop I'll fill my basket
. I'll probably use it to glue the conveyor belt as well if I can get enough of it.
It's pretty good for lots of other things as well.
The pic below shows the glue and the sealed part of the ball I was just slinging at the wall.
The slinging took the shine off the glued area and you probably wouldn't see it if you weren't looking for it.
But it looks to be at least as strong as the rest of the ball.
