Do mortising attachments for drill presses work?
I just got a LN 12" Delta at an auction for $80.
Ebay has a mortising attachment locally. Do they work, or are they just aggravation? I have never actually made a motise, so it is hard to say how many I will be doing. |

I have never actually made a motise, so it is hard to say how many I will be doing. I have a mortising attachment. I've used it a few times. Yes, it works, but it's not the end-all woodworking device. By the time I set it up and make a few test holes, I didn't find it to be a huge improvement over drilling holes with a forstner bit and chopping out the ridges with a chisel. If I had it to do over again, I'd wait until I had a need to make a lot of mortises, then buy a dedicated mortice machine. You really should chop a few mortises by hand first anyway to appease the woodworking gods. DonkeyHody "Every man is my superior in that I can learn from him." - Thomas Carlyle |

Do mortising attachments for drill presses work?
The Delta Mortisers do not fit all drill presses. I bought one a few years
ago and returned it after it would not fit my older Craftsman machine. I subsequently used one on a friends machine. Impressions: 1) It is a compromise compared to a stand-alone mortiser. It will do the job but the shorter handles on most drill presses require quite a bit of force to achieve a mortise in hardwood. 2) Attach and teardown takes time and disables the drill press as a drilling machine during mortising. This can be overcome by planning but still a nuisance. The mortiser does its work by leading in with a drill bit and squaring the corners with the intergal square chisel. For occasional mortising you can do the same thing in two steps. Attach a fence and carefully drill a series of holes of the correct width; then square corners and clean excess between holes with a sharp chisel. If you find yourself mortising more a dedicated machine is a good investment. By the way, Harbor Freight sells a dedicated machine for about $100. Not a jewel but it cuts square holes and comes with decent chisels. The hold down hardware is crappy but the machine provides a better option than the drill press attachment (IMHO).

I bought a drill press w/ that attachment years ago. I found it very
aggravating. Eventually I bought a dedicated stand alone Powermatic mortiser & I'm very happy "RonB" wrote in message ... The Delta Mortisers do not fit all drill presses.

I have never actually made a motise, so it is hard to say how many I will be doing. I bought one for my Delta DP. It works ok with 1/4" chissels. Larger chisels require taking smaller bites in hardwood. It is not as difficult to set up as some claim once you get the hang of it. I use it only when I can't use my router to make mortises (which isn't very often). I rarely need it, but when I do need it, it is nice to have. As an aside (not to hijack your thread) can't you get by without it for most things? I find it interesting that Ol' Nahmie uses a mortiser very frequently, but I have yet to see David Marks use one for ANY of his projects. Marks almost always seems to use his router for mortising and the stuff he makes is not too shabby. -- Stoutman www.garagewoodworks.com |

Bit of a difference in style. Norm generally makes traditional M&T joints.
If he were to use a router, he would have to square one or round the other. Marks uses loose tennons almost exclusively. He also almost always uses a Multi-Router, a tool most of us do not and will not have. "Stoutman" .@. wrote in message m...

I have never actually made a motise, so it is hard to say how many I will be doing. Mortise and tenon is one of the strongest joints in woodworking. Mortising attachments work well, but they take time to set them up properly and when set up you can't use the drill press for anything else. Buy quality mortising bits (yes, they are not cheap). |

Not as well as the $100 mortiser from Harbor Freight

I would have to agree with Barry, I have a Delta mortiser and it has yet to
be used. I am thinking ebay with it soon. I see using my router for any mortise to be made in my future. You use one with a plunge base. Support the router base with a 2x4 on each side of the end grain you are wanting to mortise and plunge away. "Toller" wrote in message ... I just got a LN 12" Delta at an auction for $80.

I have never actually made a motise, so it is hard to say how many I will be doing. I find the mortising attachments to be aggravating to set up and use. I quit trying a long time ago. I also have a dedicated mortising machine, which I rarely use. I've also used the PC mortise/tennon templates which is slick for short tennons, not so hot for long tennons. I have reverted to making mortising jigs for my router, and almost exclusively do it this way. I have several jigs that are somewhat adjustable. Because I had access to all these items, I could test them to see what I liked the best. custom jigs and a router wins every time, in my book. Frank |

I have never actually made a motise, so it is hard to say how many I will be doing. It really depends on how many you'll end up doing. I had a standalone mortising machine for a long time and I hardly ever used it, I ended up selling it to a friend who uses it a lot more than I ever did. I think that it, whether it be dedicated or an attachment, is something that's only really useful if you use it a lot, otherwise there are ways to make the occasional odd mortise that don't take much more time and that don't take up space or cost more money. |

I would learn to make mortises with a plunge
router and use the drill press for making nice holes. Toller wrote: I just got a LN 12" Delta at an auction for $80. Ebay has a mortising attachment locally. Do they work, or are they just aggravation? I have never actually made a motise, so it is hard to say how many I will be doing. |

I have never actually made a motise, so it is hard to say how many I will be doing. I think the drill press attachment is not worth the aggravation. I bought a Jet mortising machine with high hopes that I'd start using M/T.. In the end though, I hardly use it.. Most of what I do is plywood cabinents with face frames, and pocket screws are so much easier and faster. Before you buy anything, think about the projects that you will actually use it on. My mortise machine and Tenon Table saw jig collect a lot of dust. |

hello,
Althrough I agree for the Tenon jig for the tagle saw as they are plenty of ways to make tennons, I do not regreat my $85 HArbour Freight Mortising machine, way worth the price! cyrille "Pat Barber" wrote in message ...

I bought a Delta mortise machine a while back from Rockler. It was backordered, and while waiting, I cut the mortises for the important project another way. After the machine arrived, it sat for 4 months or so, without being opened. One of the guys in my woodworking club bought it for what I owned it for, unopened. I've not missed it. I did buy a LN mortise chisel, though. That gets used a lot. Patriarch |

Toller wrote: I just got a LN 12" Delta at an auction for $80. Ebay has a mortising attachment locally. Do they work, or are they just aggravation? Like many, I bought a mortise attachment (cheap, used) only to find it didn't fit my drill press. Then I analyzed the parts. My drill press has less than 2.5" of spindle travel, and a mortise chisel might reasonably make 4" cuts. The force to press a 1/2" mortise chisel into wood is larger than a paring cut with a 1" chisel going perpendicular to grain, which is a task I usually use a mallet for; my drill press isn't (I disassembled it to be sure) really intended to apply that much force. And the drill press column, with higher than intended force, might not be up to the load, i.e. might be too flexible. The Delta dedicated mortiser has a different kind of column. It's not an insurmountable problem, I've doodled up a design with cable/pulley construction that has zero flex on the column, and with the right cable you can put a ton of force on the cutterhead- might even build it some day. For the foreseeable future, hand-cut will be just fine for my needs. I've hand-cut some mortises, and with a Forstner bit start it isn't too hard. Even for a bevel chisel (no, I haven't got a REAL mortise chisel in the toolbox), and even in plywood and softwoods. By the way, I highly recommend doing practice dovetails in plywood and in softwood; it's instructive, and doing one in oak afterward is SUCH a relief! |

I just spent some quality time with a half-round file to make it fit. 1) It is a compromise compared to a stand-alone mortiser. It will do the job but the shorter handles on most drill presses require quite a bit of force to achieve a mortise in hardwood. I make a lot of 3/8" mortises in (mostly) cherry. The force doesn't seem excessive to me. I have considered a stand-alone mortiser, but never acted on it. 2) Attach and teardown takes time and disables the drill press as a drilling machine during mortising.

Not a jewel but it cuts square holes and comes with decent chisels. The hold down hardware is crappy but the machine provides a better option than the drill press attachment (IMHO). I don't bother trying to use the hold-down on the Delta. I just use the Armstrong method. One of the odd ways I use the mortiser: I'm making a 1" x 1/2" hole in some wheels and handles. I drill two 1/2" holes with a brad point bit 1/2" apart. I use a hand chisel (sometimes) to do a rough cleanout of the hourglass in the middle. Then I set up the mortiser with just the chisel, and use it to clean up the hole. I can index the first pass on the two drill holes, and ease up on the ends to square them off. I can't just set up the whole rig and make two holes, because I don't have a reference face on the workpieces to square up to. yours, Michael -- Michael and MJ Houghton | Herveus d'Ormonde and Megan O'Donnelly | White Wolf and the Phoenix narrowwares Bowie, MD, USA | http://whitewolfandphoenix.com Proud member of the SCA Internet Whitewash Squad |

After having bought it, I came to realize that the drill press is not really well suited for this type of work. As others have mentioned, set up is tedious and your DP is tied up until you break it down again. I have seen the Beadlock loose tenon system (http://www.beadlock.com/) and, although I haven't bought it yet, it looks like a great idea. They try to sell you the tenon stock but I think I would just opt for the router bit and make my own. Anyone here tried this system? Chuck |

I would bet a dedicated mortiser would make a cleaner hole, but who cares? You can't see it anyway. For the weekend hobbiest, I think it fits the bill. |

The bit bores a round hole using an electric motor and the square chisel
cuts the four sides by using downward force using lever action. On a drill press the downward lever is short and the pressure on the square chisels is not effective. On a dedicated mortiser the square chisel is driven downward with a much longer lever arm mounted on a much larger rack and pinion. So when you lower the lever down while boring the round hole the square chisel cut effectively and smoothly. "CW" wrote in message nk.net... Yes, I've tried it. Want one?
