twas one of my first projects with the 9x20, just a piece of 1/4" scrap
scrounged from something out of the junk box, turned out better than the
store bought ones actually.... pretty simple and straight forward
actually, I made the fore-end 1/4" for better rigidity.

So I walk on down to the corner steel mill and pick up what I need.

A corner plastic mill would be really great too.

Seriously.

Unfortunately, as I have many years of experience looking for unusual
parts, finding something which fits or which can be fashioned into what I
need is often a needle/haystack affair. Yes, it probably exists, somewhere.
The question is what and where.

...Some sort of nail?
...Some rivet?
...A 1/8" hex bolt?

A 1/8" hex bolt might work if I can find them. I could cut off the bolt to
length and turn the head against a grinder to shape it. Might be better to
use something which is more precisely made tho.

If the shanks could be 1/4" making them would be easy. But they need to fit
into the 1/8" chuck of a flex shaft.






OK, it seems you want a holder for Dremel type cut off disks.
The kind that Dremel makes, and sells.....
To use in a flexible shaft..

The shank from Dremel is dirt cheap.
And, the center is drilled on center already.

If you are determined to make something yourself,
The difficulty as you imagined is to get the screw
hole exactly on center...
Thst could be tough with a drill press or a lathe.

If you can use a drill press, you can take a small
block of aluminum, or steel, and drill and tap
for a screw.
Turn the block over, and drill just big enough for
the shank you are going to use.
The block should be clamped securely, and the hole you
just drilled will intersect with the screw hole you
jst made.
This allows you to put the shank into the hole, add
a screw to clamp it. If the block was clamped securely all
this time, the shank is now exactly lined up with the
drill press.
Now, you can drill and tap the screw hole in the end
of the shank you are making.... It will be lined up
with the shank since the shank is inserted into the
hole you just drilled in the small block.

Without a drill press, or lathe, it will be much
harder to get the screw hole in the shank lined up
exactly on center.
It might be possible. But it would MUCH easier to
earn enough money to buy the shank from Dremel,
for example, then to struggle without the proper
tools to make it.

I don't think I spent over $4.00 for mine.
