MYSTERY OBJECTS

[PanBiker]

I kept quiet about this one as I probably had one during my craniotomy. I have two holes in my skull where they gained access to saw out the bone flap. I watched a procedure the other week on TV which was a very similar case to mine although the guy had milder symptoms. His tumour was in roughly the same place sitting on the motor cortex but a bit smaller. It was only impacting his upper body with arm cramps. The neurosurgeon gave a running commentary during the procedure. With mine they used one of the access holes for the drain which I had for a couple of days after surgery. All fascinating precision stuff.

Leksell Stereotactic System

Wow!

I Googled it

[Stanley]

Well done Kev. Exactly right. I think Google was the only way to get it. I certainly had no idea until I found it.
Now for the next one. What is this.....

[PanBiker]

Is it a diamond or gemstone vice for cutting purposes?

[Big Kev]

For lining up round things for drilling 90 degree holes?

[Stanley]

Sorry but neither of you is close. Small correction, it could possibly be a part of both of them but that's not the answer and I want the name.....

[Gloria]

I’m sure I’ve seen one, but for the life in me I can’t remember where.

[Big Kev]

Indexing block?

[Stanley]

It is Kev but there is a name for it.....

[chinatyke]

Following Kevin's suggestion: Divider block?

[Big Kev]

Found one for sale on am American website...
ROSE-INDEX, 45-60-90 DEGREE INDEXING BLOCK

[Stanley]

That's the one Kev. It's a Rose Index and only made by one form in the US.
Next for shaving?

[Stanley]

What is it?

[Stanley]

No takers?

[chinatyke]

A circular measuring device, perhaps for measuring the circumference of a roller or similar item? Just guessing!

[Stanley]

You are so close China.... Give me a profession. (Look back at recent subjects....)

[chinatyke]

I've just had another bright idea! For measuring and producing a hank of yarn prior to weighing and determining the count. Sorry, I'm just guessing in the dark. Could be used by spinners.

[Stanley]

"

Is right, it was just the profession I was looking for. Look back a few days!

[Stanley]

I'll come clean later this morning China because in fact you have the right answer.

[chinatyke]

I'm no good at engineering things. Where's Gloria when you need her?

[Stanley]

Graham, it wasn't engineering, it is a tool used by a surveyor for measuring distances on large maps or plans.
Next One?

[chinatyke]

You got me with that one, I wasn't thinking of anything like that. Never seen one before. I could see the connection to measuring.

[Stanley]

But you got the use right!

[Gloria]

I'm no good at engineering things. Where's Gloria when you need her?

Watching tennis.

We're just back from Cornwall. Can you identify the plant that was growing over the pergola at our holiday cottage?
