Full or Stub Tenons on Frame-and-Panel?
I usually make frame-and-panel backs for my case furniture. I’ve been using full m&t joints where the stiles meets the rails, sometimes as deep as three inches. Is this really necessary or would stub tenons serve as well? I worried about the joints breaking apart if the carcass is ever racked.

For preference at the corners I use a full M&T for their renowned strength and longevity in service. Take the groove that you run along the length of the intermediate muntins, (or mullions) stiles, top and bottom rail---- and then run the same groove in the end of each muntin (mullion.) Intermediate horizontal rails into the stiles I find are best with a full M&T. Then knock out a piece of wide timber to fit the groove you've cut, cut it to length and width, i.e., just under 2 groove depths long, and suitable width and install it as a loose stub tenon at the junction between the muntin and the top/bottom intermediate rail(s). Drive a pin or two into each side of the joint if you want to get it out of the cramps in a hurry. If there's plenty of strength in the outside framework, the supplemental vertical muntins (mullions) should be more than adequate with this pattern of short, therefore, less sound loose tenon joint in most cases.

Thanks, Sgian.
My pleasure Joseph, as ever. But my opinion is just that. I could be wrong. Slainte, RJ.RJFurniture
I would make my decision about which joint to use based primarily on the structure of the casework. Short pieces are not as apt to rack as tall ones. Case on case pieces, depending on their structure, are not as apt as full case secretaries or armoires. In my case I would balance the structure of the case and cost/benefit issues (time usually being the biggest part of cost) in making my decision. I have found that pieces can be overbuilt and put them out of the range of salability or reason. This is not a commentary on what you are doing as it relates to whether you are building the piece to sell, for yourself or family, as a piece to be entered into a juried exhibit, etc. In any case your thoughtful concern about what will happen if your piece comes under duress is admirable.
