Got it nailed!!! Except for the switch, which I have a good idea but have to find what I'm thinking about. Will end up being a China solution no doubt. Looking for a MosFet solution already pre mounted on small board. Seems to be lots with Arduino stuff. So will be a month or two before this prototype is done. As you can see below, there is a space reserved for this. Until then, just using a bulky external button switch I put together.
Anyway..............

The end result of tonight's efforts.
Couple highlights of the production. Feel free to click on a picture to browse the album.
In this picture I had the glass tube installed. Found that it is not needed and without it adjusting the end point of insertion depth is much easier. Wanted to avoid the glass having to go through the lid. I just used a piece of a wooden stir stick which wedges nicely between the coils. This will also end up being the heat/time adjustment. Along with stretching the coil some or pushing closer together.
Had some perf board sitting around which I used as a base to mount the stuff onto. I used a small amount of epoxy to glue it to the lid. Can be pried back off if a new cup is found that the lid doesn't fit.
Fun stuff!!!
