No idea!!!!
« on: November 09, 2019, 05:17:15 PM »
Hello, Does anyone know what these are?? ( I don't ) All are stamped "left hand thread", along with the size ranges; 0-20, 0-50, 0-200, 0-300. Only history is former owner was a plumber. The left end has an 1/8" diameter spline shaft?? Thanks, Lou

Some type of valve seat reamer? Seems like dad had some similar tools.

Hello, pritch. The left hand thread has me thinking valve, too. I am not even sure if what I have here is complete. Regards, Lou

I brought these in to work, still no definite answer. All of the small spline ends are the same diameter .108. The shafts that go through the body are different diameters, and offer a different level of resistance when you rotate the knob on the right end. Also noticed were the differences in the size of the end fittings , corresponding increase in diameter in relation to the ranges that are stamped on the body. The first photo shows the differences in the ends. If you look closely at the second photo, ( squinting may be required) you may see the difference in the shaft diameters. :huh:

Lostmind, good point. Are the end sections on an eccentric so that when you turn the splined shaft at the top the bottom section rotates and is out of alignment with the longer serrated section near the bottom? Like an internal pipe nipple wrench in miniature.

Hello, Guys. Thanks for the replies!! 
"Lostmind, good point. Are the end sections on an eccentric so that when you turn the splined shaft at the top the bottom section rotates and is out of alignment with the longer serrated section near the bottom? Like an internal pipe nipple wrench in miniature". Answer to your question is yes!!!   I had the same thought ( among many others), and tried to verify, but no luck . Now that you guys are thinking the same, I will dig a little deeper. The problem that I see is that neither end spins/rotates, you need to move one end in an arc to get the other end to move in an arc. Picture moving the small spline end to the left, it moves the other end out of center to the right.  Thanks again, Lou

It don't seem like the small spline would take much force to break off.
