After much waivering for months between a Domino and a "real"
mortiser, I bit the bullet and bought a Powermatic 719T (not a
benchtop) mortiser. My personal reasons for choosing the PM include:
I like through mortises, and the PM is actually cheaper than a
properly loaded Domino.
Question... Both Lee Valley and Rockler offer sharpening devices for
hollow mortise chisels.
Has anyone used either one?
Both *look* the same, but have significantly different descriptions by
the respective sellers.
You can make through mortises with a plunge router and an edge guide. I
wouldn't let that be the clincher for getting the Domino over a "real"
To date, I have not found a need for a mortiser. I make all loose tenon and
mortises and use a plunge router with a jig for the mortises. My dream tool
is a multi-router for mortises. 'Sigh' :(
In fact, I used to have a dedicated mortiser and I ended up giving it
to a friend who uses it a lot more than I ever did. It was just one
more piece of unused equipment that cluttered up the shop. I can make
any mortise I want with a router, usually faster than I could with a
I'm on the same slope as you, kinda. I got a horizontal boring
machine. I'm getting it set up with a square chisel attachment. a few
bits-n-pieces to go before I'm making square holes, one of which is
setting up to sharpen. the cone shaped diamond hone seems like a
reasonable approach, with as you pointed out, plenty of available
hardware. and no, I haven't tried either of the ones you mentioned,
but I have seen them both in the catalogs.
a somewhat different approach I read about somewhere else is making
sense to me right now: chuck the chisel up in the headstock of my
lathe and grind the bevel from the tool post. I should be able to do
it with stuff I already have on hand.
if anyone here has comments about the two devices mentioned I'd like
to read about them also....
I've used the cone-type, very sparingly, on my chisels, and it does
allright. I also believe that a good polishing of the exterior is just
as important for cutting quality and ease of withdrawal. Nice
I've heard that, but I appreciate the reminder.
I understand that an edge is an intersection of two planes, so
polishing the outside makes lots of sense. The cones seem like they'd
do the insides properly, and the Rockler versions get decent marks on
the Rockler website.
I've been researching different options (Domino, benchtop, full-size)
for months. I've been looking for an "old-school" foot-operated,
stand-up machine, and would probably still buy it if it I find it. but
the PM has won my internal battles. <G>
I missed out on a kick-ass, foot-operated machine at a machinery
auction because they sold it before I got there!!
Yes the cone is great but as indicated by Tom, you absolutely want to polish
the 4 outer cutting surfaces on the chisel. It cuts faster and with about
70% less effort to plunge the bit and chisel. Do this immediately. I
remember the foot operated one in school. ;~) AAMOF I thought I should
have gotten one until I discovered polishing the chisel.
I actually am on the Rockler mailing list. I try to group my
mail-order purchases to save on shipping, and Rockler often doesn't seem
to have as much as I need compared to Lee Valley or Highland Woodworking.
You made me nervous! <G>
Ditto, LV cones and lapping the exterior.
BTW congrats on the big mortiser.. I lust for such a beast.
I have the LV cones.
They are pretty inexpensive and seem to work well.
That observation is hardly scientific an just as casual observation that
mortises have "gone smoothly"after what seemed to be an appropriate amount
of interior and exterior tuning.
