Building a vise post
I bought a half decent vise.
Need to mount it, bench space is at a premium, so thinking I'll weld a post to an old truck drum brake I've got and mount it like that.
The model I have has a swivel base design, with pipe clamp, and it also rotates to access that function.
What height do people recommend? I've heard a few inches below elbow height. I want this to be a bit of a semi-mobile work station.

I'd set the jaws of the vise at elbow height. If you find it too high, then you can always trim a bit off.
I've set my vise on a piece of plate welded to 50mm RHS, that slides inside a piece of 65X65X6RHS, (similar to a Hayman Reese towbar setup), welded to the side of the bench. That way I can remove it if I need more bench space, or fit a bar bender, another grinder, leaving many options available.To grow old is mandatory, growing up is optional.

Another alternative/option might be to make it height adjustable?

Knocked this up today.
Used an old truck drum brake, some scrap 75x40x5mm RHS, and a few bits of plate I picked up from a scrapper in my travels.
Overall height to the top face of the jaws is 1030mm. ie approx 40mm lower than my elbow height when bent 90 degrees.
Works well! Great height for filing, and will interface as an extended surface off my work bench.

I was getting Keen building it over the weekend, and decided I'd drill and tap some M10 8.8 bolts into the plate to make her hold (and make removal a little easier).
Something got lost in translation, and 2 of the 4 holes were off by a bit.
So I welded up the offending holes, and re-drilled, however my HSS bits were not up to task. Had some good success with the Cobalt VIPR bits from Sutton. But had even better success with the Titanium nitride bit supplied in the Sutton handy packs containing a drill and matching tap.
This justified a new tool purchase- transfer punches are on order. I have made this mistake way too many times now, when the drill bit wanders and I lose the game by a fraction of a mm.

About 2mm out. I think this was a compound error as each hole wandered a little and it converged on the last hole to make it unworkable. I didn't want to file or drill out the vise base, and didn't want an oval hole to tap, although it probably would have been OK for a hack like me.
My shed is a corrugated iron box. In summer temps of 50 are not uncommon. The dirt floor work area used to have a horrendous aviary on it, and while a dirt floor, has a bit of breeze and shade all around. I should really get around to cleaning up all the loose dirt and putting down something a bit more firm. Moving gas bottles over it is a right pain in the tuchus.

I have attached my vice to a length of PFC. This is shaped to fit on a 3" square pergola post via a 16mm bar through the post and another bar through the PFC to seat against the face of post. Two vertical slots for the 16mm bar in the sides of the PFC and holes through the PFC for the 12mm bar against the post. Just insert the 16mm bar, slide on the table and put the 12mm bar in. Quite sturdy but I would like to add maybe an over centre latch to lock it down firmly.

Is it just the angle of the slot that stops it dropping straight down?

Nice job Nev.
99% of the time the forces on a vice are across or down but sometimes it is upwards
To counteract that and to tighten the vice onto the post what about something like this?
Weld a steel tab with a threaded hole in it and add a bolt to lock the shebang to the post?
