I haven’t a lathe so I made the needed fittings using the same way
that I had made the threaded insert for my angle grinder.

Place/secure a piece of steel 30x30mm at my drill press
Make an M12x1.75 threat
And using the threat makes the needed fittings.

Searching at my pc today for something I found a plan that I had made at 03.20.2017 that I had forgotten it.
So I decided to make a quick video and uploaded. Perhaps could be useful for someone.
It is two somewhat similar versions with M10 bolts/nuts for rive nuts from Num3~6 or using M12 bolts/nuts for Num3~8.
