Its a what?

[Rik ShawParticipant @rikshaw]

I have never seen one of these devices before but its probably because it is wood related, a substance I am not overly familiar with. What is it called and what does it do?

PS If anyone wants to say its a 12" rule and it measures feet I already have your measure.

I think it might be called a bench dog … but sure JasonB will put me right.

Drill a hole in the bench [preferably sleeved] and you can clamp things down[like a vertical vice]

it's a 'hold-fast'….it's for holding down a workpiece onto the benchtop so that it might be planed or sanded etc

 

There is another part not shown whicch is the small tube fitted to the bench that the toothed arm fits into…then the screw is adjusted so that the pivoted foot can hold the thickness of the workpiece.

 

EDIT;…a 'bench dog' is a metal stop that you place the workpiece against to pevent it sliding as you plane/sand.

It is a bench clamp.there would be a hole drilled in the bench and a metal insert screwed into a recess made above the hole to give the long bar something to bite on.you can quickly adjust the clamp to height and when you screw down onto the workpiece it forces the bar away from the screw and tightens the whole thing.

It's a road map. My old dad had one just like that.  It's a kind of early SatNav made from wood pulp. The lumps of metal are used to stop it blowing away.

I have a spare bench insert which can be yours for a small donation to Help for Heroes.

[Rik ShawParticipant @rikshaw]

So now I know – thanks. Special thanks to SillyOldDuffer and his dad for delightful daftness.

I have one that looks identical, so I believe it was made by Woden.

Hi, and not only that, but back in Sept. 1977 I spent a night in Abingdon-on-Thames, on a narrow boat. Nice little pub there then by the river.

I agree the big blue metal bit looks like a work holding clamp, and does stop the map blowing away.

Regards Nick.

It is nearly a noggle clamp. It isn't quite a noggle clamp., but it gives me a wonderful excuse to use the word 'noggle' three times in one post.

New ones available from Axminster Tools, plus many other tool suppliers no doubt.

I remember "bench dogs" or "bench stops" from wood work when I was at school, but a retractable wooden post at the end of the bench, not metal as Bob suggests, probably that way at school to prevent us kids destroying plane blades, and in fact the wooden planes them selves.

Very useful bit of kit. The great benefit of a hold-fast is that, by working away from the clamp, it permits planing or scraping of very thin pieces of wood which would buckle and break if you tried to work them up against a bench stop.

Neil,

For the benefit of someone on the wrong side of the Atlantic, what is a noggle? Online dictionaries were no help.

[Speedy Builder5Participant @speedybuilder5]

Noggles prevent Niggles when planeing wood on the work bench ?

[John ReeseParticipant @johnreese12848]

Then a niggle must be a minor pita?

[SillyOldDufferModerator @sillyoldduffer]

Noggle Clamp not well known over here either. Neil is educating us again. He has no grease that boy.

[John ReeseParticipant @johnreese12848]

Dave,

Thanks.

Here it is known as a Kant Twist clamp.

Perhaps some of you fine gentlemen could collaborate on a dictionary of British shop slang to help us poor Americans.

MichaelG.

Being a pseud I had to buy a copy of Kant's 'The Critique of Pure Reason'.

The book absolutely defeated me. Although the individual words make sense once they are combined into sentences they become totally incomprehensible. I must be an ignoramus, apparently a posteriori.

Any philosophers out there who can explain it simply please?

By the way, a discussion of philosophy isn't off-topic here. The thread title is "It's a what?"  Ho ho.

A generous offer, which I'd be happy to accept if no-one else has beaten me to it.

I also have one of these without the insert; mine seems to be about 20.5mm on the shaft, though I guess it was 13/16" when it was made.

Regards Bill

The clamp shown by Silly Old Duffer was called a crab clamp when I bought it. Mine was cheap imitation, or I exceeded the design limits by stripping the female thread in the mazak/alloy "nut" part. The steel BSF threaded replacement is still intact tho'

I think you mean Zamak, a zinc based die casting alloy.
