Lamb's Tongue Gauge

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!
