ATM Dovetail dimensions

["Andre Yanoviak" <andre_y6@hotmail.com>]

Hi,

Is there such thing as a "standard" dovetail?  If so, what are the 
dimensions?

I'm working on a finder, and the commercially available mounts ain't looking 
like they're going to work as well as I'd like with my particular scope.  
However, I would like to stay compatible with their dimensions in case this 
finder ends up on another scope, or these parts end up being used in some 
unanticipated way.  Also, by the very nature of the process, I'll be making 
extra stock.  It'd be a shame to make something incompatible.

I'd guess I need something in the neighborhood of 1/2" square Al stock for 
the "male" bar.  I have 3/8" cut, 9* (degree) and 1/2", 14* carbide-tipped 
router bits.  But I'm not sure which angle is appropriate.

Any help would be appreciated.  I guess if there's no standard, following 
the Losmandy dimensions would probably(?) give me the most options down the 
road.

Anyone got some calipers, know how to measure something like this, and have 
a few minutes to help?  I'd really appreciate it.

TIA,

-- Andre
