Guess what this is a photo of!

[Uncle Bob]

Not for drilling...nor sizing rings

 

[Andy M.]

A nail set

 

[YT2095]

well now that I`ve softened him up a bit, I`ll let the rest have a bash now

 

[Uncle Bob]

Not a nail set...it could be used for that purpose if it were a big nail. And YT I suppose it could be used to "ream" something out. But that is not it's designed purpose.

 

[YT2095]

is it for Countersinking screw heads?

and I think I`ve earned at least One question, Are those dots along the one side some sort of Calibration markings?

 

[Uncle Bob]

It is not used for countersinking....

Those "dots" (as you call them) are not for Calibration. And those "dots" (your words) are all around the object...

 

[Buck]

My guess is that it's a pin that holds two things together. The taper helps align the holes and those "dots" are small holes for a retaining clip to go through.

 

[Uncle Bob]

Sorry it took so long Buck. I've been busy getting ready for a "for fun" chili contest tomorrow! It is not a pin. It holds nothing together......

 

[Andy M.]

Are the "dots" on the taperd part of the shaft concave or convex?"

 

[Uncle Bob]

Andy they would be convex..raised above the surface

 

[Buck]

Is it some sort of a key?

 

[Uncle Bob]

Not a key of any sorts

 

[pacanis]

That's what I was thinking, too. Some kind of key. I even went as far as to look up chuck keys because of that pinion gear looking end.

UB, is it still a used or needed item?

 

[Uncle Bob]

UB, is it still a used or needed item?

This one is old, and has pretty much seen it's day! I use this one for a punch of sorts sometimes. Yes, newer more modern ones are still used, and needed!!!

 

[Buck]

Is it used for some sort of measurement?

 

[Uncle Bob]

No Sir! It does not measure anything

 

[pacanis]

A drill bit..... or bore

 

[Uncle Bob]

Not a drill bit......It does not bore

 

[Buck]

Do you strike it with a hammer?

Or use it in conjunction with any other tool?

 

[Uncle Bob]

Buck it is not designed to be used as a punch, but I use it for that purpose. So yes, I use a hammer to knock the devil out of it

But....It is not designed to be struck with a hammer.

Used with any other tool?....In a very broad sense it is used with a "tool"
