You are aware of those little cone shaped sharpeners that Lee Valley sells?
Takes a drill press and a drill press vice to really do it right, but they
work very well.

Well, I went out today and paid $99 for the Harbor Freight Mortiser and did
about a dozen 1/2" mortises in yellow pine with no trouble at all and I
sure didn't predrill any holes. Just bear down on it. Are you sure you
had your cleanout shoot pointing the right way?

I use a tall auxilliary plywood fence with the board and a c-clamp. Works
great and cost nothing.

Great advice there Swingman, thats what Im going to do. I just got back from
B'Lowes and or course they dont have the better unit so Im looking now.
Theres a place that carries Delta machinery about 40 miles from me so
tomorrow I may take a drive and check them out. If my overworked brain could
remember the name of the place I would call first but I cant
remember...........Oh where oh where has my youth gone...........*sigh*

Not a question of bearing down, the chips clog at the base of the chisel and
build up on the bit blocking the flow to the cleanout. . My guess is that
I'd do better with a better or at least a better sharpened bit. I have to
work on the proper way to get a sharp cutting edge.

I've not tried the larger sizes either, they may work better.

Sounds like Delta might of copied Jet for a change. <g>

Sorry to hear you got snookered on the model, but glad you got it figured
out. I personally would crowbar the wallet for the extra $40 and get the
better Model 14-651. The reason I say this is because these benchtop
mortising machines, while capable of doing the job, are right on the
borderline of being the ideal tool, so you need all the help you can get.
IMO, the Delta 14-651 had the best head assembly going when I was looking
for one and I wouldn't hesitate to spend the extra money for that alone.

Hey Edwin glad to hear of the success with your machine. I learned something
that I'm almost embarrassed to admit. I just found out yesterday Delta makes
two versions of these bench top mortisers. Guess what. I of course got the
crappy one. The MM something or other is the model number. Cant recall off
hand. Anyway the biggest differences I can see from pictures are the base is
much smaller on mine and the switch is different altogether. The head
(here's the tricky part) is ALOT further back from the fence and the hold
down than on my machine. I mean ALOT. That's why mine hits and others
didn't. Contemplating returning it. The other unit is only about $40 more.
