John,
After the cores are hardened with CO2 is there any way to recover the sand? i.e. to "un-CO2" it? Not that sand is all that expensive and throwing the core away would be a big loss. But you seem to take such care to recover the other casting sand so I was curious.

John - good video as always and I like the fact that the time you choose to experiment is when doing a casting for Bob
I also think you should sell merchandise to those who watch your videos. I'm thinking shits, caps, mugs, key rings etc all with "Bastard!" printed on them...

I love your vids for what you leave in as much as the content. The projected core made me chuckle

love the co2 fire extinguisher John, I usually use ''pub gas'' cylinders when I make co2 sand cores with a regulator & a hollow needle, you can get refills if you have a bottle allready from a stall at rufforth autojumble, £10 a go, I go there every month with my brother,of course if you're ''in the know'' you can get 'em for the price of a jar!! he he
