is there such thing as a db-9 hood with a bore as large as a db-25 or more specifically a
db-23? Or what about a grommet to take up the slack in the larger hood?

A DB-9 IS EXACTLY the same hood as a DB-25. That is what 'B' means.
'D' is the shape, 'B' is the size, 9 or 25 is number of pins.
Did you perhaps mean a DE-9?
'E' size is used for 2 row 9 pin, and for 3 row 15 pin.
Without the size letter, how would we tell the difference between a DA-15
and a DE-15?
I have some DB-9s, they have space for 25 pins, but only have pins in
positions 1, 2, 3, 4, 5, 6, 7, 8, 20
The D-23 doesn't have a size letter.

ok so if I wanted to make a sturdy cable, db-9 at one end, D-23 at the other, is there a
grommet out there that I can purchase to make up the difference in the bores? Or do I have
to make something on one of my many not-set-up lathes. I think I lost one last week in
fact. A small one, but who loses a lathe??

hoods for DE-9 are readily available.
For DB-9, just use a DB-25 hood.
Hoods for D-23 have existed, but are hard to come by.
"Grommet"??!?
Yeah, you could make a SPACER to fill the gap for using a DB hood on a
D-23

Only in a mainframe.

I'm at a loss to understand how you use a db-9 connector w/a db-25 hood. There's
going to be a lot of ventilation it seems.
I have the D23 hood. I was going to buy a nice metal db-9 hood/connector at Radio Shlock.
I guess I'm going to have to make a GROMMET. Apparently that sort of thing doesn't
exist out there.

NO.
A DE-9 is a lot smaller than a DB-25
A DB-9 is the same size as a DB-25, usually with 1,2,3,4,5,6,7,8, and 20
connected.

You said that you wanted to make a CABLE.
You have a D23 hood. and connector?
You can get a DE-9 connector and hood.
WHERE do you think that you can get a DB-9 connector and hood that is not
just a MIS-LABELED DE-9?
WHERE did you want to p[ut a GROMMET??
2:24 p.m.
ok let me start over :)
I have a Amiga 1000 external floppy drive cable - that is the d23 plus the cable ONLY. The
cable is cut off at the other end.
I want to make this into an Amiga 600 video cable. I have a D23 connector to go along
w/the D23 hood from the floppy drive.
I need to put a DB9 on the other end to plug into the monitor. The cable connected to the
D23 is too fat though. Like me, too fat. Therefore I need to obtain another piece of cable
that will fit in the hole of a db9 hood. The problem w/that is the d23 hood has a larger
bore, so I need to take up that space.

There's no such thing as a "DB9". (Technically, 9 pins in DB25 might
qualify...)

What I've found that works when faced with a similar situation (e.g. 4
wire cable going into a DB25 hood), I taken either about an inch of
rubber or vinyl hose, slipped it over the cable (nice if you can do it
before you solder things up), and secure it with a small cable tie that
fits inside the hood body. It works extremely well.
(I find that keeping lengths of various size vinyl hose around useful).
Sometimes it can be had in short lengths for the asking if it's the

Chuck's suggestion of a wire tie for strain relief is a good one,
whether you use a grommet or tubing. Even a tight reducer will allow
the cable to slip over time, and the strain relief provision in the D-23
hood will probably not grasp a smaller cable.

C: Unless you precisely machined a grommet. But even then you could just put a tie wrap
around the cable, or w/a piece of tubing, and do your best to make it butt up against the
grommet. Even a piece of acetal/delrin would be acceptable, though not what I had in mind.
I will try the auto parts store. Sounds as good a suggestion as any.

Radio Shack used to sell shrink wrap tubing in small packages for a couple
of dollars. You can still get it online from various vendors. All you need
is a heat gun or hair dryer, and you can build it up in layers to make it
the thickness you need.

I'd be moderately surprised if you couldn't go to Home Depot or your
local auto parts store nowadays and find the stuff. RS used to sell
heat-shrink tape that you could build up and then fuse with a suitable
heat source, such as a lighted match. I don't know if it's still offered.
Many backshells (the term of art) also come with internal cable clamps.
I long ago gave up on the 3-piece + screws and bits of metal shells.
I prefer using the one-piece snap-on type of hood with nice extended
molded-head jackscrews. On occasion, I've even filled them with epoxy
resin for a more secure attachment.
A bit of black rubber hose can serve as a very handsome grommet in a
pinch.
But for all I can tell, CT may be after a flexible strain relief instead.

It's a little more costly than a grommet,

Ah, now that is closer, and explains the reason for a GROMMET!
What I would do, and have done before, for matching cable
differences (not impedance matching :-)), is to drill out
the opening of the smaller hood to take the larger cable,
although using a smaller cable and an O-ring or grommet would work.
To use as a video cable, you would need a DE-9, NOT a DB-9.
DB-9 is hardly EVER used for anything except serial communications.
Although MANY people and even ignorant businesses mislabel their
DE-9's as DB-9

You're right to be cautious. I used a cheap drill press,
with the part clamped down solidly. The well-made metal ones,
and some of the plastic ones went very nicely. Some of the
crappier metal ones not so well.
?I would have thought there would be something out

Used to be. But, then you could choose between dozens of
different hoods for all of the common sizes. And there
existed DB hoods for cables with fewer wires.
There were probably even grommets.
'course so long as it's solid, with good strain relief,
I'm not very particular about the appearance of my DB-3s
and DB-9s.
For some connectors, such as Mini-DIN, I'm not adverse
to using whatever cable is appropriate for each connector,
and ssplicing them in the middle. With a little practice,
shrink tubing doesn't have to look too bad.

I'm at a loss to understand how you use a db-9
connector w/a db-25 hood. The$
I've yet to see D-shell connector hoods that care about pin count; they
all just care about size, so a DB hood is a DB hood, regardless of
whether it's a DB-25, a 13W3, or even something really esoteric like a
DB-9. (I've never seen a DB-9, though I've seen a recent trend to try
to apply the term to a DB-25 with only 9 pins installed, for some
reason. Perhaps oddly, I've never seen the other logical consequences
of that point of view, such as calling a DB-25 with only pins 2/3/7
installed a "DB-3"....)
What you most likely want is a DE hood. Almost all of what is called
"DB-9" is actually DE-9, misnamed by someone who doesn't understand the
terminology. (Unfortunately, this includes far too many vendors.
Sturgeon's Law applies.)
As for grommets? I don't know of any designed for the purpose. But
there is a very wide variety of grommets out there designed for
sheet-metal use; it would not surprise me if one of them would serve
your purpose.
