Some of our pages contain a "Replacement Character" (�). It is a Unicode character (U+FFFD) used to replace an unknown, unrecognized, or unrepresentable character in text. This symbol often appears as a black diamond or rectangle with a white question mark inside.
Example
My fence had a bow ranging from .008" on one end to .015" at the other end, Hammer replaced it with no questions asked. The fence itself, being triangular, allows accurate 45� cuts to be made when the fence is laying on one side. There is a full range of adjustment between 90� and 45�, and the "dead stop" mechanism for 90� is easy enough to set.

Almost every page on the site allows comments. If you note this when viewing a page, please leave a comment on the page that it needs attention. And if you know what the characters should be (sometimes they are not obvious) that would be helpful.
Thanks.
