T slot width on saw table sliding table

[Hornbeam]

Is there a standard width for the T slot in modern sliding tables
I have a casadei KS1300 with an aluminium sliding table that slides next to the blade with 2 T slots machined in it along the length.
These are 18mm which is a real pain as most T track nuts and fittings seem to be 19mm
So 2 questions
1. What are the track widths on other saws so that other fittings will fit in my saw table (mine is now obsolete)
2. Is it a reasonable approach to widen the slot to 19mm (using a router , suitable cutter and paste lubricant)
Thanks
Ian

The short answer is NO.
I've come across this problem myself recently. I had some blue T-track that I bought from Rutlands many years ago, and some silver stuff I bought from them a couple of years ago, which I've never got round to using, until recently.
They are not the same profile.
The sliding nuts that I have fit the old track with just a bit of filing of the nut flanges, but the later stuff doesn't take the main body of the nut, let alone the flange, without running it down my tablesaw.
