If your machine is a ShopBot, you can use the file I designed for your cutting. There is an article posted on the ShopBot website, People page, Gary's Musings.
I have a similar machine, (prt alpha 96), how did you generate the toolpath? Did you use a specific program that considers the dovetail bit and outputs a .sbp? I love the 90 fixture you have there, did you make that yourself? Nice work!
How did you get the gantry to 'overshoot' the end of the table, because normally cnc routers aren't designed to do that. Nice clean design BTW. I'm impressed.
One of the good things about a ShopBot is that you have flexibility to do things like this. I can cut to -2.5" on the end shown and to 97.5 on the other end. About 100 inches of cutting length.
No, Ive never considered, nor do I wish to, anything but solid wood for our drawers. We have only recently started suing sheetgoods for cabinet cases.
The cost was negligible... parts on hand and a bit. I have owned a few of the PC jigs... this cut far nicer joints and is adjustable by a few thousandths in any direction. Its not made to compare with a purpose built dovetail machine. It was made to allow those accasional users that own a ShopBot, to cut dovetails without purchase of another machine.
BTW, we regularly cut 12+ wide drawers using this method.
Well put, that's what I was thinking, someone who did them only every now and then. Have you ever explored the nested dovetailed drawer boxes with sheet goods? Looks neat but I'm more of a fan of solid wood (soft maple drawers) and more traditional pins and tails (they are rounded when cut flat).
how cost effective is this? I could do this faster by hand with a portercable jig, and in 2 seconds with a dodds dovetail machine. Or is this more of a demonstration? Nice work.
All the info you should need is posted in my column (address below)

Cool video... although I come from the laser world, I'm very impressed by the capabilities offered by CNC Routers.

You can get more info on my ShopBot Web Column. Scroll down to the dovetail jig.
