Hi all

I am currently designing a post and panel chest of drawers. The post will also serve as style for the side panel.

The groove in the post will be 1/4 inch wide to accept the panel. The easiest would be to have the mortise for the rails tenon to be 1/4 inch also. the rails are 3/4 thick.

So is 1/4 sufficient or should I bother to make the mortise 3/8 or so

chest is 50 inch wide

thanks

Martin,
As Tim said the type of wood makes a difference. But a good rule of thumb is no more than one third the thickness of the wood. So a piece of 3/4” you would want a 1/4” tenon. 6/4 you could go to a 1/2” tenon.
Make sure you cut the mortise first, then make the tenon to fit the mortise. This helps prevent a loose joint, just sneak up on it and take your time.
Hope that helps,

Just my opinion, 1/4” should be fine for the maple as well as the pine. Today’s glues should insure a good joint regardless of specie, as long as you have a well fitting M and T.

i always make the tenon 1/3 the thickness ,
ie:
1 1/2 ” stock , 1/2 tenon ,
3/4 ” stock , 1/4 ” tenon .
otherwise the mortice cheeks are to thin ,
in my opinion .
