Carl,
Do you dovetail in the back of the drawer too? I always debate about what to do when I reach this step - I've done it both ways (dovetail vs. dado) but usually end up going the dado route in the unlikely event that I would someday need to replace a bottom.
I dovetail the two back corners as well. You can notch out the back so you have to staple the drawer bottom into the drawer back.
Mine are all enclosed though. If I have to replace a bottom, I'd rather just remake the drawer. I do it mostly just because you cut the front & back the same size. I try to make everything as idiot proof as possible, adding another step and forcing me to think at work is a recipe for disaster.
I really need to get something to get these things whipped up faster. Laguna has a automatic dovetailer that looks pretty slick, but I've heard far more bad things about Laguna tools than good. There's other options out there, but man are they spendy. There's a cnc dovetailer that I saw a video of on Youtube that could do some crazy stuff.
Or I just need to have the whole process taken care of by some Indonesian sweat shop.
(edit-) I've got a decent list of widgetry that I want. I really need to get a panel saw, the Striebig I'm looking at is about $25k new and will shave a whole mess of time off of doing cutout, plus add a whole mess of accuracy. I'm going to need a new compressor sometime in the future, I'll be getting a screw type with an air drier built in. I also need to buy or build a downdraft table, summer isn't so bad with the doors open, but in the winter with everything buttoned up it gets too dusty when sanding with a orbital. Plus I'd like to pick up a couple more shapers, setting up & tearing them down for different setups on the same job is baloney. I've currently got three, once does a few jobs, the other two are dedicated to one job each. After that though......
