No the thickness of the foil won't make much difference and the foil tape might work but the overlap between each price could be a problem
If I were you I would make a few small capes with different numbers of plates and test them to see how many plates per foil you need
Thanks RIP, much obliged for the reply, yes the overlap of the tape had me concerned. I have some conductive glue perhaps it I coated the edge before puting them together, worth a try I suppose. I think someone earlier in the thread had tried two plates, and like mine the C dropped dramatically. So I may look into Mike's idea of gluing it all together, he had some good results, just not sure about the wood glue. Looks like some more searches.
Made some searches and found an adhesive that might just be the thing, it is good upto 400c, and it is in Australia, so no high postage costs. I am toying with some ideas, that may or may not be viable, it would be nice to get some thoughts on the issue. I have made a drawing Of what I am thinking, it is open plan, just imagine it all compressed together. I intend at first to use this to compress everything until the adhesive has cured properly, then I hope it will be of no further use. The clamp can be made of either plywood or plastic, I don't think it will matter, though the plastic would be much heavier, not sure how the ply would stand up under oil, should be ok. One other thing i am wondering about, should I seal the outer edges of the plates or let the oils seep through. Ernie
