Thanks for the welcome GH

I checked out the Northcott site and have decided not to drawbore (mostly because of my rookie status). I did like their tapered pegs with the head on the end.
I have also decided to reduce the brace width to 4". Any suggestions for cutting mortise deeper than my 3" frostner bits allow? (I realize I can chisel) or through cuts?

Thanks for helping me in he pre-planning state.

Lloyd.
