I've made one out of wood so far. I'm looking for a piece of aluminum similar to the one you posted and make one like that. If anyone knows where to find a small block of aluminum that please let new know.
The punch nail on the saddle valve I tried bent the first time I attempted to use it. I suspect there may have been some operator error involved, but the experience convinced me it wasn't for me. I had been successfully using the dremel, but that can be a hassle and I want easy. I forked over the $40 for a vip carto punch which works great.
I'm sorry to hear about your cracked tank. I don't know about the bad batch possibility, but I know some juices can cause tanks to crack. I only use juices I know won't crack my tanks. So far, so good. I hope I didn't just jinx myself by saying that!
What do you guys do when your carto dies and the tank is still full of juice? How would you swap it for a new one without making a mess?
what spin method would you be referring to?
