Hello Rustednuts,
It should look familiar as I took it from pictures posted here on Stovebolt. As far as the hydrogen is concerned, here is a quote from the original article.
"No noxious fumes are produced. The method is self limiting: it is impossible to over clean an object. Small amounts of hydrogen are emitted in the electrolysis process. Good ventilation or an outdoor work site is all that is needed".
I have great ventilation, with a 16 foot ceiling and a 14 foot overhead door, which I leave open. A lot of the time I use a fan also.
I really appreciate your words of caution. Sometimes we either get lazy or don't know enough about stuff that we get ourselves in trouble (usually ME.) It's words of caution from others, if we heed them, which really help us all. Again, I appreciate your words of wisdom.
Martin
