Hi Dean,
I saw another design which uses a single bolt with a large square head.
The bolt screws into the BS bed (probably has a lock nut underneath) about where my little block is, and a horizontal thread goes through the large square head in the same way as mine.
This means you only have to drill one hole, and can screw the block thread up or down to align the cross thread level - I hope that all makes sense.
Looked like a good simple design to me.

But at least you tried.

Perfectly clear Rob. Undecided at the moment. I usually have a better idea of how I want to do something with some visual clues. Put some bits of metal in position. SWMBO despairs of my inability to visualise something she had described. Usually to do with the house, furniture, curtains etc.

I know what you mean.
I thought afterwards you could just use some 15 mm round stock, machine it down to cut the thread, cut off the stock leaving about 20 mm unworked, mill a flat each side of that section, then drill and tap the cross thread through the flats.
You can see on the one I made that I had to put a spacer plate under the block to get the right height - my square section wasn't quite big enough.
It's a great mod. You won't get stressed anytime soon about moving the primary vise jaw.
Cheers

It depends on the timing of when I do it. I am currently without an operating lathe.
I could strip the saw down to the base and mill a flat section. I can find some square of sufficient cross section. That was my initial thought when I saw your picture. It was a fleeting thought tho, I must say.
