I just received a Delta 14-651 Mortiser and I am wondering about the setup of the auger bit to the chisel housing. The manual indicates that bit extend past the sharp portion of the chisel anywhere from 1/16" to 3/16" "depending on the type of wood" one is working with. If one is working with a softer wood does the bit extend more or less and the reciprocal then hold true for harder wood? Or does this distance vary according to the properties of individual woods (e.g. does cherry behave differently than soft maple?).
In just playing with the machine for short time, it also seems that its efficiency is directly related to how well the auger bits pull up the chips and expels them from the chisel housing. The chips seem to have a tendency to really jam up everything. Is there anything (waxes or whatever) that could be applied to the auger that might move the chips better. I suspect that one could also goof up the glue joint if it were contaminated with wax or a lubricant.
Thanks in advance for your responses.
