Topic tags/keywords: designing joinery mortise tenon drawbore pins question william and mary prie dieu

In my current Prie Dieu build, I have pondered several transitions from the William & Mary frame to the kneeling platform. On the original desk on frame there is a 3/4 inch half-round transition between the frame and desk. I want this same 3/4 inch half-round along the edges of the platform, I intend to have mitered breadboard edges. I also want to notch the platform around the front legs of the frame.

 
I envision the joint between the frame…
 

 
... and platform looking like this …
 

Anyone see a(ny) potential problem(s) that I do not see?
 
Thanks!

As this is a very young crowd (at least we still have delusions of that) I thought that you were thinking of some ways to make it more knee friendly!

The wooden joints that you illustrate should be strong enough to support anyone.

Kenny – Thanks!
 
Tony – Thanks! Experiencing a little join pain are you?
 
rjR – Thanks! Knee Friendly … HA! This is being built during Lent … it’s supposed to hurt! LOL!

The only thing I see that I have to be careful of … is remembering to pin the 3/4 inch rail in the front legs before I pin the 1-3/4 inch rails with the sticking.

Hey Ron—the last drawing with the three joints coming together is neat, but I’m curious about how it’ll actually come together. The left and right front-facing small mortise and tenons are cool, but how much (if any?) material is between those joints? In the drawing, it looks like the mortises are very close, like they’d be right on top of each other, perhaps with no material between them. So then I guess the tenons would all be touching? Maybe the scale of the drawing hides some of the material that will be there? Or maybe even without material it’s still strong enough? Just wondering what it’ll look like.

Great question, Dan. Obviously you spent some time studying that drawing! Well firstly, imagine the 3/8 inch x 5/8 inch tenons coming together as a finger joint. Given that, there will be a void between the mortises where the three tenons meet (represented in red).
 
             
 
I hope this answers your question. Thanks for asking!
