5" Knurled Handle....but for what??

[dimwittedmoose51]

Threads appear to have a slight taper to them, so is this a handle for a mini hammer/kit tool or some weird item some one made in a metal shop project.  No logos or numbers anywhere. Old enough to likely not be Asian, so I'm stumped again this week.  TIA gang!!

I never took metal shop, so I must ask- can you make such nice knurling in a one-off project?

Metal shop was in 73, so it's been a while... but you are cutting that down in a lathe and you would use a knurling tool to apply.

Could also have been a handle for a clamping jig. I've seen die makers go somewhat over indulgent at times ;P

Yea, the knurl is the easy part, oddly, the pipe thread is the hard part....

It would make a great handle for a small tapping hammer :)

I was a diemaker for 38 years and I used a bar like this to turn dies on their side to seperate top and bottom. We had over 1000 dies and those that were too big to handle by hand had 1/2" to 5/8" threaded holes on all sides to handle them. Sometimes we used a chain fall, sometimes a handling bar. Or it could just be a threaded handle.

Hey wait a minute, a diemaker???
  Ohhhhh hoo hoo going to pick a brain over this!!!

  So, knurling? I only have a single knurl holder. Never did have a dual or certainly not a turret.
I got some loose knurls one time, but haven't mounted them.   
Do you have any advise for me? I have a small lathe, 6X18 Atlas.

Also, I always started with the lathe off, apply a bit of pressure, turn it on and increase the pressure. This is wrong?

Here are a couple knobs I made. Look em over and see if anything occurs to you that would make it easier for me?   
I generally use a lathe the same way I'd use a file. By guess and by god, as they say. heh

Sure looks like the handle from a high school machine shop project hammer.

[dimwittedmoose51]

I would agree with that!!

A good knurl takes lost of pressure and a sturdy lathe. Knurl rollers in good condition will displace metal much better. There are scissor type knurl tools that are brought together with a screw that don't put pressure on your lathe. Also, keep knurl teeth clean, but don't get wire brush caught in work. (Yes, I did a few times.) I guess you know brass knurls better than tool steel, but you can do either with good results.

The piece reminds me of a piece of the holder for my Lansky knife sharpener.  The threaded end goes into a base that can be clamped to a bench.  The top bit, above the knurl, fits into a hole on a clamp to hold the workpiece (knife) in place while you work on it.  This allows you to quickly flip workpiece over without reclamping.
  I am thinking this is a user made piece for something similiar.
