From FWW #178 (July/August 2005):
Properly set up and operated, a mortising machine cuts straight, square-sided mortises in relatively short order. The author had eight benchtop models shipped to his shop for a close examination. The Delta 14-651 offers a  toolless method for securing the hold-down to the shaft; a riser block kit, which adds about 1-3/4 in. to the plunge depth of the mortiser; a better-than-average fence; and the best access to the drill chuck. A gap at the fence bottom allows chips and sawdust to escape. A good choice for the money.

Parts are poorly machined. On my the fence is not perpendicular to the table.

Fair tool... BUT... upon second use the switch box began smoking profusely and I turned it off immediately to avert a fire. After examination, it turned out the motor start capacitor was faulty, a pinhole appeared in the side of the plastic capacitor case, and a 'goo' had begun oozing out.First contacted local Delta service center and eventually the national service department. I was told the capacitor is not available! It's not even shown in the parts list. The only way to get it is by buying a new $165 motor w/capacitor!!!Thanks, but no thanks. I'll just spend a few more dollars and buy a better mortiser from a competitor! Would it really be so hard to make ALL parts available?(BTW, tool was new two years ago and just given to me in Sept 2007 - that's why it was out of warranty...)I hope this problem is not indicative of all power tools now being made overseas...

Solid tight construction, practical features, and an excellent price. Does a good job of cutting square holes. Is it a high speed production machine? Of course not, but it's not $2,000+ either.Depth stop and the fence are easy to adjust. The included made-in-China 4-piece set of hollow chisels and bits was surprisingly good for an inexpensive set. It won't win any awards, but I think it was almost free.The hold-down on mine was a little too sloppy, with the two-prong hold-down not being able to make both prongs come in contact with the work. Also, the locking knob is in an awkward position.A swing-out door makes it very easy to access the drill chuck.I'm very satisfied.
