You are correct I did not mean 1 mil but 1 oz.
1 oz is about all I use for faster etch.

But one mil copper would be like 25um thick, as far as i know only
18um and 35um is available easily?
(It is called 1oz and 1/2oz of copper weight per some specific area in the US.)
I look forward to your photos, thanks.
