drill holes for installation of connecting dowel with out a drill press
I am looking for a way to drill perpendicular hole on a flat surface of wood for connecting dowel installation.
The tricky part for me is that the standard way of using a drill press won't apply well here due to the non-flat and non-parallel surface on the other side of the wood piece I need to drill on, also the whole structure that's composed of a number of wood pieces jointed together might be too delicate/complex in shape/large in size to put on the drill press nicely.
What I'm really hoping to find is something of a small mobile guide, some flexible hand held device which mounts a drill that ensures perpendicular drilling, and the only thing it's relying upon is the flat surface where the hole is located.
I am not looking for that accurate drilling here; most of the dowel connection is hidden in the finished project, all I want is a mechanical connection for two surfaces that's reasonably precise.
