Well I borrowed a mortising machine from a guy I work with. Its the older model delta and this guy and the guy he got it from said it works great. Additionaly there was an article in last months FWW about mortiser setup. With all this I did a modest initial tune up on the mortiser to make a couple of test cuts since I have not used one before.
I guess the part I was most surprised about and was wondering if it was normal was that the sides of the mortises seem to have scalloped edges. As if the edges of the auger bit are wondering a few thousands outside the edges of the chisel. Albiet, the scallops are very small but I was expecting the walls of the mortise to be very smooth. Can anyone shed some light on this. Is this normal? Is it the bit or is there a lot of runout on the bit. Also I set the bit and chisel clearance as per the FWW article and the bit seems to get very hot. Enough to make white oak smoke. Is this right?
