Ok as promised
Here is my attempt at a SIP pot ,critique welcome
Made from 2 /20ltr black buckets one bucket cut at 14cm from the bottom this was the divider for the reservoir, saves me having pipes or bottles to hold the divider up . I used a short piece of 90mm storm water pipe with a cap and I used a 90mm to 100mm reducing bush and trimmed the outside 100mm bit off to give me a bigger shoulder to support divider .
The top half of the bucket that was chopped is fitted to the top of the bucket with screws from inside out into the flanged bit handles go through, trimmed a section of lid to hold fill pipe ,skewer and cork to indicate water level .
Drain pipe fitted and holes drilled in divider and foot.
Let me know if I've missed anything
