I'm making up some flat IDC cables which terminate in a 0.1 inch pitch
IDC header socket. This fits onto a board connector with 9 pins (one
omitted).

Clearly I'd like to fill the unused hole to make it impossible to plug
the things in the wrong way round. I'm probably going to use a blob of
epoxy, but does anyone have their own easy way of doing it?

is a proper Polarizing Pin or Key available for the series of connector
you're using?

Not on that list. These are the 0.1" pitch headers used on things sich as
disk IDE cables; the holes are tiny. I haven't been able to source any,
and they'd probably cost a fortune.

You can buy them with the hole missing.

and they'd probably cost a fortune.

Not when you buy them with the hole missing.

Bit of wire of the correct diameter for a tight fit, snip off. Job

A long time ago I bought some plastic pegs that you could inset for this
purpose. They were V-shaped to hold into the hole and had a flat very thin
top to cover the hole.

Might well have been RS or Farnell.

I tried Farnell but I'll look at RS. They do at least exist, then.

Yep, definitely seen them.

Next best thing is to dip a the end of a cocktail stick in epoxy and
push it in firmly, cutting off the excess with flush cutters for a
professional finish :-)

Not too much glue in case it migrates.

We used to key our cable so you had to put them the right way around.
However as I only ever ordered the ready made cable I've no idea where
you get the bit of plastic. Thinking about it I've never see one loose -
so I can only tell you the head was square, and had a mark in the top as
if it had been broken from a bit of sprue.

That's the ones. Just ordered somew from RS. I note that some of them
actually come with a handle and you break them off yourself after
insertion.

Took a long time to find them though!

Nope, because cocktail sticks are much too thick.

You'd be much better off cutting off a single pin from a
dead drive and gluing that into the hole you want to block.

Not too much glue in case it migrates.

And doesn't need to be epoxy, any decent glue will be fine.

What's wrong with a single tooth from a fine hair comb? Far easier - shove
it in, cut off with craft knife. Her indoors won't notice a single tooth
missing!!!!

I tried about a dozen phrases on there before I happened on a similar
product and thus found the phrase...
