Jean-Phillipe, I don't know anything about those bubble sextants, but I do know about tools. There are three common, U.S. sizes between 1/16 and 1/8. Look here http://buy1.snapon.com/catalog/tools.asp?tool=all&Group_ID=585&store=snapon-store for 5/64, 3/32 and 7/64. This set ( http://buy1.snapon.com/catalog/item.asp?P65=&tool=all&item_ID=72489&group_ID=585&store=snapon-store&dir=catalog ), for example, has all the common sizes. I bet you could find the same sizes from cheaper manufacturers, too.
