   Mike, I'd consider a slot mortiser for this. You'll get burning, clogging and rapid dulling in hard maple, especially end grain.

   *When you first get your mortising bits, unless you buy the high end ones, they will need some work. I polished my chisels with sandpaper on a flat surface (drill press table would work), up to 400 grit. The auger is the real workhorse of the set up, and it needs to be sharp, and also polished. The interior of the chisel should be free of burrs and a smooth as possible. I have also found that spraying the chisel and auger with a teflon dry lubricant spray, helps prevent clogging. This spray does not contaminate the glue joint. The 2 most important things needed to prevent burning are to properly set up the bit according to the instructions, and to keep a even steady pressure on the tool while cutting. As long as the chips flow out, they will carry away the heat, but the second they clog you’ve got problems. Have you considered a plunge router, with a spiral bit? This approach, while messy, and loud would be faster.

   *I agree with Rob...Slot mortisers and loose tenon is the best way to go. The laguna/robland is a good entry level unit. You'll have all the mortises done with a slot mortiser before you even get started with a chisel type mortiser. One bit will cut hundreds of mortises.

   *well, im intrigued.. how much for something like the robland? though this is likely my only production run...Do those use end mill type bits? and the 1/2 x 2" deapth is no problem?

   *http://www.lagunatools.com/mortiser.htmIt's not only a production tool, it's a one off custom tool as well. You make mortises in all pieces and insert a loose tenon.
