The Myford traveling steady has a fairly flat base and mounts with one screw but the fixed steady has a square feature in the base that snugly fits in the gap in the bed for precise centering.
Boxford lathes do resemble the Hercus 9” lathes with slight differences.

Boring an engine block
with a portable borer. Which is a little top-heavy, so had to stop the block from tipping off the bench:

Three things in a machining vice
Modifying the size of some T-slot nuts:
IMG_4170.jpg
Now, we all know gripping 3 things doesn't work.
No matter how hood your vice is, how much you tighten it,
and how much you dead-blow hammer the things into the vice jaws,
two of the things will be gripped, and one will not.
Thankfully, in this case, the middle thing was loose.
I was milling slowly with a HSS cutter, so a little bounce and wobble is bearable.
Basically, the middle thing either slid away from the cutter until it hit the outer thing and was stopped,
or it bounced up and down until both the leading and trailing edge of the cutter face was over it.
Having the middle thing loose was actually helpful,
as I could remove it and test fit,
then slip it back into the vice for another cut.Nigel, from a cave FULL of unfinished projects and lost tools.

Lathe chuck clearance hack
Was boring a hole in a rectangular plate:
IMG_4497.jpg
in the 4jaw, but the narrow side was too close to the chuck jaw step. So, when the cutter got too close, I wound out those two jaws, and put some HSS square there so that the boring would clear the jaws.Nigel, from a cave FULL of unfinished projects and lost tools.

Hi Kryn, Guys,
Now that is a useful tip ! Not just for multiple items but useful if the work isn't parallel vertically between the jaws.Best Regards:

I use Aluminium TIG wire all the time to hold parts for squaring stock.
Depending on which way it’s out of square you can put the wire vertically, horizontally or nearer the top or bottom of the jaw etc.
It’s soft enough to squash and conform and give a bit of friction.
I’m not a fan of hard on hard for clamping (particularly if there any chance of vibration) as there’s not much grip if things start to slide.

Have about half a 20litre drum of the stubs, about 150mm long, if anyone wants some.
The ape rentices can't be bothered joining the stub to a new rod.

Triangles in the bandsaw
Dividing a rectangle into two pointy triangles. I have tried it in the vice before, but the twist, and slip, when the blade breaks through it is risky, so:
