I'm curious....
I got a glimpse of a shop made tool recently. I think, but am
definitely not sure, that it's called a slot mortiser. I have a bench
top hollow chisel mortiser -- this tool is not that.
Let me describe it.
The guy built a waist high table. Mounted a motor under it which
drives a pulley which drive and axle which has a drill chuck in it.
The drill chuck had a long bit in it -- I've been told it's an arbor
bit which cuts in _and_ sideways.
Now along side the table were some bars whch ran vertically and
horizonally in both x and y. A small platform was somehow mounted in
the bars. The platform holds the wood to be mortised. The table goes
into the drill and then slides left right with respect to the bit.
I DAGS and found a router based device at
(http://www.woodcentral.com/shots/shot390.shtml) but it doesn't look
the same.
I will be able to view it next Tuesday night but my curiousity is
killing me. I hope one of you might be able to help before next
Tuesday.
Update:
I did not get a photo -- feel kinda funny asking the cabinet maker if
I can take pictures of his tools. However, I did get a much better
look.... He uses a piece of machinery from INCA -- a small table that
would move in three dimensions. I searched for a few minutes on the
web but did not find it. He said he bought if from Garrett-Wade "or
someplace like that" years ago.
Once you see the table, the rest is easy to imagine.
I'll still try to get a photo. BTW, I went to
alt.binaries.pictures.woodworking and it wasn't obviuos how I get
pictures there. Any hints? I'm using Google to get there.

Horizontal Boring Machine/Mortiser
Third and fourth image in this page. This one's on the end of
the Robland X31's jointer/planer cutter head which is chain
driven by a 3HP TEFC motor.

Add this slick jig and you can cut mortises at various angles.
That's real handy if you're doing chairs.
http://home.comcast.net/~charliebcz/RaysMortiser1/RaysJIG1.html
Cutting mortises in both parts and then using a "loose
tenon" to hold them together is much less risky than
the tradiional mortise and tenon - the length of the
part that would normaly have the tenon is the actual
"visible length" rather than the "visible length" PLUS
the length of the tenons on each end.
The "loose tenon" can be made from what would other-
wise be scraps - and harder than the parts being
joined if you'd like. You can make up a few feet of
the needed "loose tenon" and cut off what you need.
Make it too loose and it's no big deal - make another
WITHOUT affecting the expensive parts that show.
If you want to use a router to make loose tenon
mortises check out this one. (all one line so watch
the line wrap)

Handy this loose tenon thing.

that sounds like a slot mortiser.

this one is powered by a router motor rather than a belt and pulley
system.

do you own or can borrow a digital camera? please take pictures and
post them to the news group alt.binaries.pictures.woodworking.
There have been a number of plans in ShopSmith and ShopNotes
for very similar "jigs"... They are normally a fairly
complicated goat rodeo from the stand point of operation.
Most are "router based" and require a lifetime of screwing
around trying to duplicate the jig....

and there are several more....

Slot morticer, aka debollocker.

Sounds a lot like it, but end mills don't work for cutting timber
(tried that one).
I'm not a fan of these things. They need an expensive cutter (and you
really do need that expensive helical one if it's to work) so they're
not a bargain substitute for a morticer. They also take up a fair bit
of space, especially with good tables. Most of all though, they cut a
round-ended mortice, and I just don't like those.
On the good side, they're a good way to put quite a bit of
wood-shifting power into a piece of timber that can be an awkward
shape or size. It's easier to lead big stuff into a horizontal slot
morticer than it is to get in under a vertical.

I 2nd the motion. I'd like to see it because it is home made, like a couple of
lathes that were shown in ABPW recently. Get some good details and angles
and post @ 640x480 please.

they seem to work OK for me.
generally I'll run them in the router or the mill drill. I like the 4
tooth spiral ones. nice clean cut. not cheap though.
