another what is it tool

[wkndfirewood]

Found this while going thru some box lots and this was in a box with a flaring tool. I'm hoping that those knowledgeable can shed some light as to what this tool is and what it is used for

pipe cutter with a dull blade.

 

[glennster]

it looks like a bead roller for tubing, prolly for some type of pressure fitting

Possibly used to roll around copper refrigeration tubing to reduce it's ID so a smaller tube will fit snugly inside to be silver brazed in place.

flaring tool for tubing Have used 1 similar when doing copper tubing

 

[glennster]

ya know, i have been looking at this tool for a while. i noticed the wheel is set at an angle and obviously turns. seems if you chuck some type of tube or pipe in this thing, and spin it, it looks like it will form a spiral in the tube, almost like a thread. but it would be a square cut groove. interesting tool!!

did you try googling the number stamped on it? Bill

Darndest thing I've seen. Don't look like it would last long as a "groover" from the friction wear. Never saw a need for tubing with a half-arsed acme thread on the O.D.

The way the handle necks down with a knurl on the tip makes me wonder if the roller wheel is adjustable in and out ???

Looks too small to paint the stripes on a barber pole.

What about the stripes on a fat candy-cane ?

 

[Eric in IL]

I think ya got it Bob ! Looks like the angle of the roller might overlap part of the last revolution instead of making a thread. I vote necker-downer.

I have used a swaging tool for expanding copper tubing, so it fits over the same size to be soldered together. Made for refrigeration, looks like a pin punch with a step in it.

Does the knurled rod on the end change the position of the wheel?

 

[Dan in North Houston]

Somebody went to a lot of trouble to neck it down and knurl it. But I don't think it could adjust the wheel because the lock down screw hole would prevent an adjusting rod from being connected.

 

[Dan in North Houston]

Does the knurled end do anything? Unscrew? Maybe a reamer or something being stored in the handle?
With the angle of the wheel, what would be the "thread pitch" that it would leave if you ran it around a tube? I liked Bob and Eric's idea of a necker-downer, but if you wanted to slip two pieces of tubing into each other, I would think a swag to enlarge one end would be a lot easier and more uniform than necking down the other end.

 

[glennster]

maybe the knurled knob is to hold the lock down screw???

 

[Eric in IL]

Agreed, besides that the axle for the roller looks like it stays put.

Thanks for all of the replies as to what this tool maybe used for. I was surprised that Google did not provide any information
Dan in North Huston ? the knurled end is a removable pin 3/8? x 3 ??, otherwise it just spins in the handle.
Mike(NEOhio) - the knurled rod is not connected to anything in the handle.
Bill mart - that was my first thought, and did not receive any results.
Glennster- the knurled rod is not connected to anything in the handle.

I could of used that once, I took a job repairing the plumbing in a house that had froze up. The soft copper stretched just enough so a coupling would not go on to be soldered!

If it is a "necker downer" the knurled pin probably goes inside the tubing open end while working to determine final internal size & perhaps to prevent collapsing.
