I posted this on the Aussie forum, but it may be of use here ..
I have been looking for a hold down for the Hammer K3 slider for some time, to be used like this ...

Something like this eccentric clamp by Felder ...

The trouble is that they are very expensive, somewhere between $150 - $350 USD, and with the Aussie Dollar tanking, try doubling that!
There is an "inexpensive" one available on AliExpress ($75 USD), but price is without shipping (and you still need to double the price for AUD) ...

Then I came across this one, made by ToughCut, available at Total Tools ... in Perth! For $75 AUD. I jumped on it.

When it arrived, I was impressed by the quality of the construction ...

Of course, there was an issue - there was no way to fit this directly to the Hammer slider (it was designed for a ToughCut slider). And I wanted it behind the crosscut fence, where there was no space ...

To give an idea of the size of this thing, the plate for the screw would not fit the track ...

I measured the screw diameter at 21mm ...

The knob at the top intrigued me. It did not appear to do anything. I assumed, from the photo, that it would turn to tighten the base screw, but it did not. It was simply fixed in place.
The screw looked like an M8 thread, but that was difficult to determine in this form. Then it occurred to me that the side clamp had the same thread and knob ...

Checking this, it was indeed an M8. Great, they opened the door!
So, the plan was to up-end the shaft, using the M8 screw to connect it to the plate securing the crosscut fence ...
https://i.postimg.cc/R0c9Lq1g/HD6a.jpg
Cut off the knob, trimmed the bolt, drilled and threaded the plate ...
https://i.postimg.cc/7LvwzSzC/HD8a.jpg
This was a good and solid fit ...
https://i.postimg.cc/nzpxRZ0p/HD9a.jpg
Here is the finished product (what do I do with the thread at the top - cut it off or add something?) ...
https://i.postimg.cc/HxzgFKh5/HD10a.jpg
Note that the clamping knob on the side was relocated to the rear (to clear the blade guard) ...
https://i.postimg.cc/qq7TrLPF/HD11a.jpg
Turned sideways, out-of-the-way ...
