Ernie,
I’m building a roll top desk from a Furniture Designs plan of a few years back. I made and sized my sides and top today and realized that the dovetail joining the top and sides is different than any I have made before. It appears from the plan that the dovetail joint is in sidegrain on the sides. Is this correct, or should grain orientation be vertical on the sides of a roll top desk. I would appreciate any help.

Dear Jamie
I could answer a little more definitively if you give me the plan name or url you are using so that I can go to it on line. The normal way such case goods are done, dating back to the 18th Century, is to half-blind dovetail the top and bottom into the sides. This puts the tails in the top and bottom and the pins in the sides. (The pin is cut into the end grain.) The joint would show from the top or bottom and not from the sides. I can draw a sketch is you need?
With best regards,
Ernie Conover
Ernie,
The grain orientation on the sides of the top section (the part that has the track for the tambour) is horizontal in the plan and the through dovetail is cut into side grain. It appears that this might break off under stress. Would there be any reason to compromise the TD for another reason? The plan was a roll top desk plan that furniture designs offered but I haven't been able to find it on the web. I also posted a question on Woodmagazine.com/general woodworking forum. Another explanation of the question might help. Thanks. Jamie
Dear Jamie,a dovetail cut into plank grain would have little strength. This sounds like bad design. Again I need more information. Can you scan the existing plans and post?With best regards,

Ernie,
I can't scan. Can you e-mail me a phone #?
Will do back channel.Regards,
