Hi Randall
The absolutely easiest way to search this board is via Google. Simply include the following phrase "site:fer3.com"
For example, if you wish to see all the NavList information on mercury toxicity, from Google type "mercury toxicity site:fer3.com". Google interprets this to mean find all occurrences of 'mercury' and 'toxicity' but only on the Navlist.
Frank has also included this feature in his Search NavList function, using this exact Google feature.
They have identical functionality because they are indeed the same function!
If you don't mind typing the additional "site:fer3.com" as part of your search string, then just use Google. If that's too much, then navigate to the NavList page which does that for you.

Will anyone who has used mercury for their AH answer a few questions for me?
How much mercury is needed for how large a surface? (Ounces or mililiters)
One photo showed a tray about 14 cm 4-5cm. How much to fill this for use?
Can you name a source to purchase mercury?
How much does mercury cost?
Should I use a wooden tray or metal?
Should the storage bottle be metal?
Does mercury dissolve rubber o-rings?
Are special permits from the EPA needed to buy or use mercury?
I understand toxicity is low if you do not touch it or use it in an enclosed area. Is this true?I am going to try to make a copy of the atique versions I have seen pictures of, with the rextangular tray and the bottle threaded to facilittate transfer back and forth.
Refer me to previous ppost if this has been covered before.
