Re: What is this item?

The first one is definitely a screw thread micrometer. Typically they use interchangeable anvils (the tips) for different thread pitch ranges. They are for cutting threads on a lathe to measure the pitch diameter of the groove, as this is the only true way to get an accurate read on the groove depth. The way most machinists do it is with thread wires, and standard micrometers, and then look up their results in a table or calculate using a formula, as having thread mikes and anvils for all common sizes of threads is expensive. Most of the time, when you make a thread on the lathe, you try and get ahold of the mating female thread and just cut it to fit by feel.

Notice my occupation! I actually know how to use them and read them (as well as how to cut threads on the lathe)! Contrary to what some might believe, they are not a precision C-clamp!! Even though I have rarely had the need to, as all I own are dial types, I do know how to read vernier calipers as well. All the engineers in my design group, except for me, use digital measuring instruments. They come get me when their batteries die

"They come get me when their batteries die"

That's just sad.

All the jr engineers at work are amazed I can do math in my head, as most people my age can. w/o a calculator they are helpless.

I thought it was a Guantanamo truth extractor.

Re: What is this item?

I do no have a thread mic, but have a number of others up to 6 inches and have other calipers up to 24" most all vernier some of the calipers are of the dial type, no batteries included, even have some hole mics. I bought my first micrometer when I was in High School and still have it.

when I cut threads I usually just use a nut or measure the out side of pre cut and match it, most of the things I do are not needing that measure of precision, and there are only so many things one can afford when it is not you every day job, so some of the specialty tools are on the dream list,

I should find the pictures of my old lath and post some "what is" it pictures, it will swing over 24" and has between centers 7 foot, but is over 125 years old. and the serial number on the bed is #2, I found a nearly identical picture of it in a book done on machinery by the census office back in, 1880.

Please do post pictures and some info on your lathe.

Re: What is this item?

You're right, it is, but it was sold as "slip joint nut pliers" and boy does it come in handy when you can only turn about a 1/2" before you hit the disposer or wall.

Re: What is this item?

For what this is worth oil filter pliers come in more than one size.
Besides Channellock it may be worth checking out what Cal-Van, K-D
and Lisle depending on the job you need to get done.

Re: What is this item?

Now here is something that will get some of you thinking. I bet most of you can tell me more of less what this is, but I want model and type/series numbers if you can figure them out. By the way this picture was taken of the front of this item using a flatbed scanner with it resting on the glass. I don't own a digital camera yet.

Okay, Woussko, I've got to give you a smack here.

You have just about every little do-dad and gizmo I know of, and many more that I don't have any idea about (yes, I know that this one is an old Simpson electric multi-meter, but other than that, sorry). And yet, with all of this, and all of your knowledge, and resourcefulness, and ability to sort out a bargain.....you still don't have a freakin' digital camera??!?!?!

Come on bud. Maybe we should all start a little collection for Woussko. Maybe have a hotdog BBQ day to raise money for a digital camera?!

Re: What is this item?
