Hello all, final parts are made and pictures follow.

These are the lid ring holders.

The split collar to clamp the CV boot.

A small valve to allow excess pressure off when testing.

Here the valve is installed and now in to the house for testing.
First test: to apply heat to the pot. Alarm..ding..ding, air leaking out.The CV boot that was brand new is not. It was found at our local sunshine store's take it or leave it and I should of left it. This is a major problem Ed and I will have to go to C. tire and buy one now, looks like a delay.
Second test: Will have to reboot egor. Some glue and back on the heat. Alarm...ding...ding, popping sounds like corn popping, the pots bottom sucking in and out. The base of the pot is to thin. There is lots of pressure and vacuum. This pot sucks I mean blows. I will have to add a heavy steel plate to the bottom and of course this will cause a delay. Ed it looks like you will get yours working sooner then mine.
I will take the unit apart and inspect the inside. Glue on the CV boot repair let go and the displacer may have been popping, the thought of replacing it with a lighter unit now seems like the a good idea. What to make it with is the next question. It's weight is a factor. Lots of R+D and having loads of fun. Failure is an option. Back to my career.
