Thanks Leven. I seriously looked at building a Horizontal Mortiser, being the HorizontalMike that I am ;-) but really like the simplicity of a vertical mortiser for the moment (need to get some projects under the belt).

Thanks for pointing out some things I have NOT thought about:

”The block the clamp is attached to should not go up all the way or
should be removable to allow mortising in the center of a stile or

BINGO! Maybe I could just shorten the vertical fence to start just AT the beginning of the mortising opening and use one of my Veritas dog-hole surface clamps to hold the removable vertical clamp/board. That would make this setup more flexible.

”This design would only be useful for mortising stock a fixed distance from the stock face”
This is why I am making the opening 2in wide. I have depth adjustment abilities with the router fence, but just HOW MUCH MAX DEPTH ADJUSTMENT DO I NEED from the edge? 3-inches? 4-inches? Right now I am looking at building rather simple Mission style tables and such… but I am sure I will progress from that sometime in the future.

” clamp is inadequate…”
I’ll add a second and use additional furniture clamps if needed.

”You really need to plan to get a clamp head pretty close to right on
top of where the mortise is being cut. ”

I am thinking that making the vertical block clamp/board independently anchored to the front of the workbench MAY help me take care of this?
