@Ciderhead,

Just a heads up on the jubilee clip you use to hold the bag to your hop spider. It would be better if it was replaced with a stainless steel clip, or even with cable ties. The clip you use is galvanized. The zinc coating on galvanize would not be considered food safe. While zinc is an important mineral to not be deficient in, excess zinc is not a good thing at all. Worse, however, is if free zinc is ingested by mouth. When swallowed, it becomes zinc chloride when it reacts with stomach acid. Zinc chloride is very corrosive to stomach lining. You might like not to have to worry about that.

Apart from that, the spider is a cool idea.

JD you are absolutely right and even though it wasn't in direct contact with liquid, steam was condensing and dropping back into my brews, so after the second brew with it I got a stainless one on fleabay
I also got rid of the galvanised bolts that were sitting on the side  in favour of this design with  qualpex pipe and with rebar sealed inside the pipe(Melted the ends) for strength it wasnt  strong enough to support weight on the bucket
