Lamb’s Tongue Gauge -
 
While working in the shop today, I decided to add a chamfer/lamb’s tongue detail to my Reformation Era Prie Dieu, along the sides.
 
               
 
A lark’s tongue is a simple scoop from the arris to the face of the chamfer, as see along the stiles and rails around the raised panels.
 
               
 
A lamb’s tongue, on the other hand, is an ogee consisting of opposing arcs. The detail I was looking to achieve required having to lay-out twenty four quarter inch ogees. I decided I needed a template or gauge.
 
I tried to find a few scraps of wood (12:46 PM) …
 

 
… once found … I cut out a body 7/8” x 1-1/4” x 2-1/4” (12:53 PM) …
 
               
 
… laid out opposing 1/4” radius arcs on 1/8” thick pine (1:21 PM) ...
 
               
 
… cut 1/8” channel in the end of the body … inserted shaped pine piece … secured with pins (1:43 PM) ...
 
               
 
… and … voilà (2:10 PM) ... a Lamb’s Tongue Gauge for 1/4” chamfers.
 
               
 
Keep an eye on my blog … Fr. Chad's Prie Dieu … to see this little guy in use, soon. Thanks for looking!
 
I made another lamb’s tongue gauge for four different size chamfers … 1/4”, 3/8”, 1/2”, and 3/4”. Check it out here!

Lark’s tongue, very interesting. This is the first I’ve encountered this, and I must say that it adds a nice touch to the rails and stiles around the panels. Provides a great “hand made” quality to the piece, think I’m going to have to incorporate this on a future project.

But this blog was about the lamb’s tongue gauge: good idea to make such a gauge, to ensure consistent results with all such features in this Prie Dieu. Looking forward to seeing it in action.

Thanks, Tom. Typically, the lark’s tongue is a simple scoop from the arris to the face of the chamfer. I got this variation from Peter Follansbee, the king of 17th century furniture. In one of his blogs, Peter mentions that the lamb’s tongue doesn’t “go” on a rail with panels. The lamb’s tongue is seen most often vertically along the edges of cabinets and legs.
