MYSTERY OBJECTS

[Tripps]

Would it be an RTTY modulator / demodulator? Thanks Ian, you have restored my self esteem. I expect Stanley will know more about them than I do though.

I cheated a bit and came up with http://www.textandgraphics.eu/subdomain ... o7070.html
Which I suppose is related on Telex communications , but their spec seems to go to 850?Hz as well. 170hz apparently was some kind of movie.
I guess the box could have something to do with the recent : http://oneguyfrombarlick.co.uk/viewtopi ... 592#p27592 and http://oneguyfrombarlick.co.uk/viewtopi ... 594#p27594 posts by Wendyf.

Bang on Tripps, the gubbins were all self built including the PCB's, not an off the shelf job. The shift frequencies were a bit of a giveaway if Googled. I'm going to start a new thread in the Amateur Radio section for homebrewed kit.

Gloria was in the right area and Bodge got it dead right. It's a catch plate used to drive a work-piece mounted between centres.



You need a collection of dogs of different shapes and sizes which clamp on the work-piece and engage with the catch pin on the plate.
Here's the next one for you to mull over.



Tripps, in this case you're right but not because I have any knowledge of electronics, just that I've read Ian's new topic on his Shack. Sorry If I get to sound like a know-it-all, I'm definitely not. I have a limited store of knowledge and love sharing it!

[Bodger]

Only a guess from the colour, Jewllers rouge ! sorry Tripps if youre wondering why engineers and jewllers need rouge

[TheProf]

Looks like a rough cast block of soft metal, ready to be melted down and used, to me. White metal for bearing shells?

[Stanley]

Bodge is right. Picador buffing compound for dressing buffing wheels. This one is jeweller's rouge for use on non-ferocious, the compound for steel is a white block.

Try this one....

[Bodger]

Is that a drift slot ?

[Tripps]

I agree - almost certainly Bodge.

My previous remark about SCG's range of knowledge was genuine admiration. He has experienced a great deal over the years. Not infallible, but impressive. Latest example - Sue mentions Healey Dell - he knows who pointed the stonework, and has a photo of it readily to hand . Worth the price of admission on its own.

[Stanley]

Aw shucks....... Thanks for that David, I have a warm glow. You're right, a varied career and being a nosey bugger!
I'll spoil it all now by saying you are both wrong! Have another look and try again. Clue, made by David Brown at Huddersfield when they were a great firm!
PS. What's a drift slot?

[tmason]

Adjustable reamer/boring bar?

[Gloria]

Is it some sort of ratchet??? Apologies for technical terms

[Bodger]

drift slot, an aperture in a morse taper sleeve where a tapered drift is used to to put pressure on a drill tang to aid ejection of same
Re David Brown, gear boxes?. some kind of automatic tapping holder,

[Stanley]

Bodge, I knew that but couldn't see the relationship. Our new contributor tmason has got it, what a splendid first post! It's a very expensive adjustable reamer/boring tool. I think DB's must have made them for finishing bearing housings in gear box cases. Carbide tips on the blades and I can't remember how I got it, one thing is certain, it would be for nowt! Right, try this one....

[Stanley]

Got you thinking?

[Gloria]

A hardened bush from a drill jig?????

[tmason]

Would this be a headstock morse taper adapter ?

[Stanley]

Glo, you're right, it's a hardened bush but not for a jig, Tmason is getting there, it's a Morse taper adapter but what for exactly?

[David Whipp]

To convert Morse tap into Esperanto? Rosetta Stone style?

[Bodger]

It fits in the head stock, thus enabaling the facillity to turn between centres, but you will still need a dog

[chinatyke]

It fits in the head stock, thus enabling the facility to turn between centres, but you will still need a dog

You engineers speak a different language to us mere mortals.

Does the dog guard the facility whilst your head turns in the soup?

[Stanley]

I think you need a bit of a nudge. Here's a clue:

[PanBiker]

It's a large version of a pin chuck, no clue what it's called in the giant size.

[Tizer]

I think Catgate would have replied to the last two mystery objects with `ruler'!

[Bodger]

Colette would have grasped the use for it if she was reading the post, but she would need a draw bolt, but not for her cross bow!
