FInally got to use my fancy new Delta (14-651) mortiser last evening. The set-up and all the other stuff associated with this toy was relatively straightforward. I did a few test mortises and found the chisels sharp, easy to swap in and out and simple to fine tune.
After lining up my first actual workpiece on the machine (the leg for an outdoor bench), I switched on the machine and began to lower the chisel into the wood. After entering the piece, the handle broke off the machine. Yikes. I shut off the machine with the chisel half inbedded in the wood. After closer inspection, the gear that holds the handle and manages the raising and lowering of the chisel had broken in half. The cast iron piece had cracjed into pieces. Metal fatigue?
Delta is shipping a new piece, no questions asked.
