Thought I would strike while the irons hot. On the back of my parrot build, I thought I would get a bit more practice and use up the bits and pieces I had laying about, so I've had a go at making a crimped liebig that I saw in Mcatac's thread Another Pelican Build with a twist viewtopic.php?f=7&t=8280.
I wasn't able to get 25x15x15 reducing Tees as used by Mcatac - Bunnings here only keep 20x15x15, so I have made it 700mm of 3/4" over 1/2". I crimped the 1/2" core with vice grips at 50mm centers as instructed by Mc. It worked a treat. The crimped pipe fitted nicely inside the jacket (just a bit of resistance on one of the crimps) and water flows freely through it.
I intended this just to be a bit of practice, but the finished product was better than expected, so now I'm encouraged to go on and build something to attach it to. Would this be suitable for a 2" pot still, something similar to Doubleuj's plan in thread viewtopic.php?f=7&t=10181. or would the smaller pipe condenser still work with Mcatac's Pelican plan? I'm considering getting a T500 boiler.
