I know this has been discussed a few times, but maybe the photos and sketch will help someone who is considering doing the same thing.

A while ago I bought a mitre gauge (similar to ) from Banggood and have recently found time to make some adapters, based (I think) on David Best's idea.?
- I used 30x20 EN3B (bright mild steel), rather than aluminium, because I was concerned (needlessly, I suspect) about side load on the thin vertical section.
- I used two nylon-tipped 4x14mm grub screws for the lateral adjustment and two 8x8mm nylon-tipped grub screws for the vertical adjustment and locking. If I were doing it again I would use 5 or 6mm diameter screws for the laterals, and 10mm long screws for the verticals. The holes for the laterals are clearance-bored about 15mm deep to avoid the need to tap the whole thing.
- The mitre gauge is fixed to one of the adapters by removing the large washer at the end and replacing its M5 screw with a longer one, which engages with a tapped hole in the adapter. It doesn't seem that the other end needs to be secured.
It only took a couple of hours to make the adapters and early experiences suggest it was time well spent. The mitre gauge has a means of adjusting-out minor errors and drops into the adapters with no wiggle room, so should be repeatably accurate. I can see myself using it as my standard cross-cut fence for smaller jobs.
