The old top mortise (18x6x8.5 cm) in the post is squared, and the tenon plug made and sized. I had to build up a plug from spare ash pieces. Same wood difference trees. I can wiggle it in half way, at which point I will need to push harder or tap. But I don’t dare try a full dry fit or I’ll never get it out again unless I bolt a handle on it.
I can get each respective end to go in full depth, with a gentle push, so I’m confident it will all go at game time with mallet coaxing.

This is roughly where the bracket will go and replace post length. A bit less.
The U part will be a wider grab than shown; as much as possible.
I don’t need lag screws over 30mm for the bracket mounting, but I’m having trouble finding that short length for M10 wood threads.
I do find the size with metal threads. I don’t see why those wouldn’t work for M10 x 30mm holes. That’s a lot of grab area. Our bedroom doors are hung on similar thread type.
