For this project I want to make a nice aluminium intake plenum and associated pipework to/from the intercooler. For this I will need an AC tig welder. My tig welder is DC only, bit of an oversight when I brought it.

I looked into 'community workshops' in London. There seem to be a few starting up. I went for a tour of Building Bloqs in north east London yesterday in north London near Tottenham. Very impressed with their facilities and staff. I would strongly recommend anyone in the area to go and check them out. They have facilities to a very high standard and I think their prices are reasonable.
