Just didn't want to put all the good info in the General Chat thread where I'd never find it again.
Someone at class suggested that bunnings had some sort of snake cubby for kiddies toy that would do nicely as an agilty tunnel.
And GSDs said PVC piping works good for agility poles. Someone at class said rose poles/stakes and someone else said broom poles cut in half. Trouble with these - is how do you attach the PVC piping to the ground? I'm pretty sure if I put a tent peg in the bottom of the pvc with silicone and tried to hammer that in, it wouldn't hold. I've seen variations on the broom poles using big nails and metal hose clamps to stop the wood from splitting... but I like the idea of using PVC - just don't know what to put on the end of it to make it stay attached to the ground.
I don't have any welding equipment though I know people who do.
