Is it spring loaded?

 

[Eddystone]

Is it threaded internally from/at both ends?

Is it threaded internally from/at both ends?

Threaded internally from one end looks about 30 mm x 1.75 thread

 

[Boringfrog]

Could it be some kind of puller?

 

[hilldweller]

Something like a clutch centering tool ?

If the threaded end has the two flats I would suggest its an elaborate stud extractor.

It is possible that it is a work piece that he did as an apprentice machinist.

I know what you mean but the fact it is threaded internally ?

 

[Steve and Denise]

Thee two flats are on the other end like a cap but all one part. I feel the knurled ring was to assist screwing it up quickly the nip it up with the two flats on the end.

It looks like a collet from a milling machine to me.

It looks like a collet from a milling machine to me.

That would make good sense as to hold a cutting wheel ?

 

[injebreck99]

Looks like a left handed kerfuffle pin extractor, seen 'em loads of times.!

It looks like a collet from a milling machine to me.

I was just going to say that. But most of the ones I have seen have splits in them and only threaded internally at one end, unless it is a tool holder?

 

[jockaneezer]

Going by the dimensions, I'm gonna say it's actually sized in Imperial measurements. It looks kind of familiar, I've used something like it for fitting bearings and oil seals. Maybe @Enword or @Jaws might have an idea ?

Usually the miller 'head' is designed to take different adaptations depending on the cutting tool used.
I suspect if this is one then the cutting tool screws into the thread.
The split collet type would look similar but without the internal thread.

Whatever you do don't twist it as it is in fact a 'neutron-electroplasmic wand'. Careless usage can inadvertently cause waste water to be released, solar panels to malfunction, batteries to discharge and a-frames to disengage.

 

[andy63]

is the internal thread a normal thread or left handed..?

 

[magicsurfbus]

Light Sabre. Does it have 'O W Kenobi' etched on it?

Is that similar to Dr Who's sonic screwdriver ???

 

[xsparks]

Its a sonic screwdriver as used by Dr Who surely you must be able to see that?

 

[Just smiffy]

It looks specifically made, in a tool shop for a jig.... it would be helpfull to know where the father worked and what he did.

We made lots of these type of tools for specific jobs on small production lines...

You beat me to it pappajohn.

 

[Mr B]

Looks like an internal measurement tool....
Wind it out till it touches the sides, then measure exact with external micrometer

He was a hoarder of many things but I will ask the question at the weekend when I see him in the pub.

 

[Jaws]

Not spring loaded.

Couple of questions
what was the dad 'in to' ?
Did he work on cars or bikes ?
Did he have any sort of machinery at all ?
What did he do for a living ?

 

[mitzimad]

i doubt its home made with a cardboard box
