I really depends on the type of mortise for me. Larger ones I will drill out and square up with a 1/2” mortise chisel. Other ones, I’ll use a mortising machine for, especially when I have a lot of them to make.

I use a router to the depth of the haunch, then take out the full depth of the tenon with a benchtop morticer. This works for me because the hold down and fence on my morticer are pretty lame, the groove cut with the router keeps the mortice chisel in exactly the right place.

I use a bench top Jet mortise machine. Were I do do it now, I would strongly consider the Domino. It has greater flexibility. I did once use a PM floor model mortiser and that was quite nice as well. Both of these are pricey however.

Larger mortices I drill out first with forstner bits and then use bench chisels to clean up the waste. Smaller mortices I use mortice chisels. I have done a few each way and they definitely require practice and experience to get them right. Mine are not at the level I would like, but getting there.

Depends on size and type of wood. Soft wood, I crank up the hollow chisel mortiser. Smaller, it can be a lot easier to do by hand. Depends on how I feel as well. Sometimes it is fun to chop them out by hand.

Benchtop mortising machine. Mine is a Delta. Never Looked back.

Funny, I hate mine. I just do them by hand with mortising chisels, I have the RI chisels, took the double bevel away and it takes me almost just as long to do a mortise than it took with the machine if you count set up time, and clean up of the mortise.

by hand.

If I have a lot, I’ll drill out the bulk and clean up with a mortise chisel, but if it’s just a few, I’ll cut the entire thing by hand which makes staying in the lines and maintaining a squared mortise easier for me.

Depending on my mood and the application I’ll use either my horizontal slot mortiser and loose tenons.

My pantorouter for cutting the mortise and matching tenon.

Or this jig with my plunge router and loose tenons.

What are you looking to mortise?

I have mortise chisels, a slot mortiser, a chain mortiser
and a hollow chisel mortiser… plus some plunge routers.

For a couple of mortises the plunge routers are the
quickest way to go. The hollow chisel machine
is quick to set up too. I have to move machines
around to pull mine out though.

If you are looking for reasonably quick setup, decent
accuracy and modest cost, get a 1/2” plunge router, fence,
and spiral upcut bits. A few simple to make jigs make
mortising with a plunge router reasonably quick
if not a barrel of fun due to the noise, dust, and mental
focus required.

Delta morticing machine. Made a lot of mortices for my kitchen remodel. Accurate and quick. Grizzly has a nice one that’s heavier duty (has a cabinet base), but way above my budget. They also have a kit to turn your drill press into a morticer. Includes various size collars to fit different quill diameters. If you use a router, it’s easier to round the edges of your tenons than to square up the holes.

If its just a few, I will hog out the waste with my bit brace and the appropriate size bit then clean it with a chisel..if there are a bunch will use the mortice attachment on the drill press, which also needs to be squared and cleaned with chisel.. if they are bigguns, I use the brace and a 3/4” mortise chisel with my 2 1/2lb wood mallet.
It all depends on how many and how big.. just my two cents.. Papa..

I use a router to cut most of the mortise and then mortise chisels to square them off. I hope to get a mortising machine before too long. Because my mortises truly suck. But the router sure is better than bashing it out with chisels and a drill press.

I use a plunge router and a saddle jig attached to my router plate I made in about a half hour. I plunge both ends then take light passed cleaning up between the two ends with the router and jig. Been using it for ten years, works fine. I have a LN mortising chisel that doesn’t see a whole lot of action. I cannot seem to justify any additional machinery (DOMINO) unless I’m doing angled mortises, but even then I can often jig it and use my plunge router

I enjoy working by hand if there aren’t a ton of them to do. Deep (over 1.5”) ones get bored out with brace and Irwin bit, followed by chisels to clean up and square. Some small ones just chopped out with pig sticker mortise chisel. I find I can more easily do precise, clean work by hand, mainly because it’s a lot of hassle to design templates and jigs for machinery to keep it under control. It’s also a lot easier to do angled or shaped (eg tapered) mortises by hand. I like to say, if I can figure out how to lay it out and mark it, I can cut it.

I will frequently do the drilling with a forstner bit in the drill press for medium-sized mortises. The depth stop makes for consistently flat bottoms, but that doesn’t really matter most of the time.

If I have a bunch of the same type, I use a plunge router with upcut bit, using a template guide bushing and a 1/4 hardboard template.

Rounding off the tenons is definitely faster than squaring up machine-cut mortises with a chisel, but it just feels wrong. I think it’s slightly weaker, too, but probably not in any remotely meaningful way.

Delta dedicated (was about $250 at the time including 4 chisel sets). and yeah the the hold-down sucks (from what I can tell the cheap brands are all the same other than color). I ripped 2×4’s to exactly the machine’s table height and I clamp them to the bench to serve as table extensions. with a little more support I find that hold-down is not really big deal since I take shallow passes.

The past two weeks, I have been using a Greenlee mortising machine. It is a lightweight, about 500 lb
machine that came off an old battleship. It and its accessories were discontinued in the 1950’s or earlier.
The bearings are lubricated with a drip oiling system that you have to adjust and carefully watch, it does
not take much oil. I will try to get a picture and post it on here next week. I am helping a master cabinet
maker finish his own custom quartersawn red oak kitchen (why do the call it red oak when it is white?)
We just finished assembling about 75 door and drawer frames yesterday. I cut all the 1/4” mortises in the
stiles on the Greenlee. It can handle up to a 1” mortise bit all day without getting the 2 HP motor warm,
and makes my Shopsmith mortising attachment look like a kids toy. We have all the panels glued up and will
be sanding them to the proper thickness next week, and borrowing his sons big panel saw to cut them to
the correct size to fit the frames and tagging them to keep them in the proper order so that the panels and
the stiles will all have continuous grain patterns showing. All this, and he is even paying me to play in his shop.

I have a Jet mortising machine, but the hold down does not work, so I do most by hand and chisels.

Do the mortise machines out there also make the tenons? My CNC makes the mortises very nicely, and it could make the tenons, but it would be far more trouble that it’s worth to use the CNC for tenons, so I’ve just made those on the router table.

I have used a plunge router with a home jig to center the bit in the past. But recently I bought a General bench top mortiser. I am now working on a large picture frame with mitered corners. The General can cut the slot up to 30 degrees from normal, but cannot do an angled cut that will give me a slot and a tenon that is 90 degrees to the face of the miter. So the question is, do the mortises need to be at 90 degrees to the face of the frame miter?
