MYSTERY OBJECTS

[Gloria]

Not 100% sure but----Is it a roller for the end of a sine bar perhaps??

[Marilyn]

my thoughts exactly, Gloria.
What is a sine bar?

Could it be a type of hook race? I have something similar in my sewing machine...I think.

[Tizer]

What is a sine bar?

It's where mathematicians do their drinking Maz.

[Marilyn]

Eeeee....I'll pay that one!

[Stanley]

Come on! There are enough of you who know exactly what it is. Have a look at Shed matters....
And then post a now one!

[Gloria]

A lathe saddle stop?

[Stanley]

Well done Gloria! (One or two had seen Shed matters bur were keeping stum.) Try this one. Exact description please!

[Marilyn]

A draftperson's devce...for drawing scale/technical plans/ diagrams?

[Stanley]

Not there Maz but you are in the right area of precision measuring..... A very specific use though and I may be being a bit hard on you all. Mysteries are thin on the ground now!

[Gloria]

A special adaptation of a 90% Vernier Caliper. Never seen one though.

[plaques]

Its a gear tooth vernier calliper. Tesa made some nice instruments, a bit chunky and expensive but well made.

[Stanley]

P has it. The reason for the 90 degree configuration is that one vernier measures tooth depth and the other width. Essential for accurate mesurement of racks, splines and gears.

Next for shaving?

[Stanley]

Leaving me to rack my brains? Try an oldie....

[Marilyn]

Keeping stumm....

[Stanley]

Good Lass! (It was a Maz Mystery in the first place....) (and yes, I keep them all on the hard drive!)

[Pluggy]

Automatic air bleed for something or other ? Lets the air escape from something that is normally full of liquid.

[Wendyf]

I remember this one.....I think it belongs in Maz's utility room.

[Stanley]

I thought I knew what it was but after Wendy's post I'm not too sure!

[Stanley]

I think you'd netter tell them Maz and then I'll post your latest one.....

[Wendyf]

If I remember rightly this is a simple valve that sits in a drain in the utility room floor, so if a washing machine suffers a flooding event the water can drain away.... but no nasties can creep in from the depths below.

[Tizer]

And the nasties that could creep into Maz's utility room would be a magnitude nastier than ours.

[Stanley]

I think Maz is being cruel to all of us......

[Marilyn]

Yes...it was in the floor of our previous Laundry.
It stops suds from the washing machine coming up, whilst at the same time it will drain any water away should the Laundry sustain a flood, such as if a hose burst or a sink overflowed.

[Stanley]

Here is the latest object from Maz..... Like her, I am keeping stum.....

[PanBiker]

I assume the last one rather than the bowl of nuts and bolts?
