RE: Austin BT12 spanner - JoeRowing - 09-08-2022
Ok. Let me know if you need anything.
Fwiw it's quite a poorly cleaned up forging. The spanner bit is ok but the handle bit much less so
RE: Austin BT12 spanner - JonE - 09-08-2022
so what was the advantage of the double ended? Is that because the 7 spec became more complicated?
RE: Austin BT12 spanner - bystander - 09-08-2022
Generally speaking, the main feature of proper tappet spanners is that they are flat and thin, particularly if they are single-ended and designed to be used as a pair. I can't really see the advantage of a double-ended spanner, as you usually need to hold the tappet screw and the conical nut at the same time?

Typically one end is left handed and the other is right handed (I'll get my coat)

I have a pair of replica original pattern ones which are from the 1970s.
So check with our specialist suppliers.

What is the objection to repurposing an old 1/2" af or 13mm spanner with a couple of minute's filing and a hacksaw?
RE: Austin BT12 spanner - Steve Jones - 09-08-2022
It's what I did years ago, Colin. Still have it, still use it.

Hi Marcus, do you intend to make a batch of these spanners and offer them to the A7 community in the same way that you have offered other useful tools?
RE: Austin BT12 spanner - Marcus Ling - 09-08-2022
Hi Graham,
I have been asked by a guy in Invercargill to make him a pair so I will get a few extra cut for those who might want them. I just need to sort out the size, I presume that the original BT12 was pressed out of flat sheet rather than a forging so was hoping someone could post a photo of an original.
Cheers
Marcus

Came across this:
"AUSTIN TOOL KIT TAPPET WRENCH / SPANNER BT12 | #161141801" https://www.worthpoint.com/worthopedia/austin-tool-kit-tappet-wrench-spanner-161141801
but how reliable the description is is anyone's guess.
