I guess now I wait :scratch:
Did a little video of the coiling jig not that its anything special just a bit of angle.

The mixture is hardening nicely I was able to open up the terminal openings I thought the cement might bind to the ceramic but it hasnt and the tig gas nozzles slide right out so they will be held in with a little of my modellers clay. I unscrewed the inner form and even got it to move a little going to give it few days before I remove it completely though, Only moved it to give myself a chance of removing it in one piece.
Also to the base underway.

Got the inner form out with a minor break at the top however as said on the blog I read the rubber tubing wouldnt come out without breaking the channels even when it was cut in half not only that but I had failed to secure them tight enough and they tried to float so I have wonky channels. However it not totally ruined they are seperate and run in one channel from top to bottom just need to rethink how I am going to keep the element in place.

A few years ago I helped a friend build new pottery kiln. It was made in sections from a single mould. To get the grooves for the element we used foam gap filler from the builders merchant which you can get in 16, 20 and 25mm. After we pulled the sections from the mould we just torched the foam out and cleaned up the gap so the element could be pushed in. As far as I know the kiln is still in use today

Also to answer your question, just use some element pins like these http://www.paragonweb.com/KilnAccessory.cfm?KID=178
