Mystery object

[mainmarine]

anyone know what this is, I bought it in a job lot of boating items some years ago. When you move the lever accross, the jaws tighten to grip [a rope I imagine]

The extrusion matrix for a gripplethripwurbley.

The handle is designed to cut them off at the length required as the die forces the antimony/gold mixture through the heating chamber to the compressor breech.

It looks quite old, (but in beautiful condition) so you may not have to go on a Health and Safety course before you use it.

Don't forget to earth it before you start it up, though.

Instead of earthing it, should I connect it to the Terra Firma of the same planet that your on

As usual, Sarabande is talking without the benefit of firsthand knowledge. This is in fact the pre-tensioner for a knurlbox extruder, used before injecting the LITHIUM/antimony PRIOR to extrusion. This is a an extremely hazardous operation and full method statements and risk assessments apply.

Do NOT earth it.

You're all miles out. It's a Rottweiler testicle measuring caliper.
Just open the discs, place either side of the mutt's balls and turn the handle until the discs are a snug fit on the balls.
Then read off from the scale.

Try it.

 

[Mudplugger]

altenatively as the metered scale is an exorbitant price, a simple decibel counter will give the same information....the louder the howl..the tighter the crank!

 

[ThereAndBack]

It's a kitchen - with some odd item on the table.

[mainmarine]

Just tried it on the rottwieler, its now a shitsu

 

[Lakesailor]

Aren't they all?

 

[Heigaro]

If you've ever tried to creen a sternwender you'll know just what this is. It's the pre-tensioner for the gripper - or, more correctly, the mord gripper. Tensioning the mord in any other way is nigh on impossible but, if not tensioned, the necessary intimate contact with the recirculating mechanism is out of the question.

The device is undoubtedly worth a lot of money - especially if it's original. Did you see it on eBay??

What a bunch of tossers!! does no one recognise a self tailing spaghetti server when they see one?

 

[sarabande]

You're being dreadfully unfair. My grandfather had one and as little children we used to play with it almost every day. Then the earth strap fell off one day, and my little sister was transmogrified.

 

[bilbobaggins]

Aha! So that's where it's got to.......

Friction brake? Powerful jamming cleat? Winch self tailer? Sorry to spoil the party by trying to be serious - it's just my nature to be contrary.

I think, sir, you'll find it's spelt "griBBlethripwurbley". not "gripplethripwurbley"! At times, the ignorant tosh spouted on here by people who should know better AND with such conviction, fair snurbles me!

Still, I must agree, it is a particularly fine example and in very good condition too!

 

[Avocet]

...but then again, I suppose it could be a home-made self-tailing conversion piece for a non-self-tailing winch! It might be worth trying it in the boats winches to see if it fits!

 

[JasB]

Judging by the handle it looks like it should be mounted vertically. All the input my small brain can manage I am afraid.

 

[Twister_Ken]

Has a distinct 'prototype' look to it, so it may be something that never caught on.

 

[BrendanS]

I've been looking for one of those for years. Would you consider putting it on for sale forum?

 

[MacW]

I think searush is on the right track, looks like a boombrake.
