Going to have an yard sale/ craigslist ad and I found a few more things that I have no need for and want to unload.

What is all this and what should I list it for?

The first pic is inside micrometers. If you aren't measuring the inside bores on some larger parts, then they are not worth buying, unless you get them for a hell of a deal and want to flip them.

The dynomometer.....I know what they do, but not sure how that one works. Dyno's are used to measure horsepower and torque.

The last picture is a dial indicator with a magnetic base. Useful if you need to watch any movement that has a close tolerance. It can be used in multiple ways, as in a lathe, a mill, you can use it to check runout.

But then again, depending on what you do for a living, depends on whether they would be beneficial to your job or not.

I don't know about the dyno, but everything looks to be in good or better than good condition. If I were selling it, i would list the items from top to bottom at $150, $100, and $75.

And you have to understand, when selling machinist tools, you will get nowhere near the price of what they sell for. There are thousands of machinist out of work, and retired, so that means that if they don't have a home shop, and they don't do work like rebuilding engines and such, the tools then become pretty much useless to them. You can list them at a high price, and hope for the best, or list them lower, and take what you can get.

Thank you all for the input. I like to check eBay for pricing but I do not alway feel it is a realistic example of what things will sell for.

Farmall450, the only thing in the case is the Dynamometer

Well, that's for measuring force inline I believe, what I'd call a dynometer is one of these bad boys.

I'll just ask. Why do you have tools that you have no idea what they are? :dunno:

Different types of dyno. That is a tensile dynometer. Used to indicate a maximim tensile force, commonly used for measuing lifting loads for hoists, rigging and such. Technically dynos measure a force be it linear or rotational, the other units can be calculated through the input parameters.

Yes, it measures force inline. Torque is a rotation force applied (inline) at the end of a moment arm.

One of the earliest types of engine dyno was a de Prony brake (sometimes mispronounced as a "pony brake")

The upper and lower bearing blocks were tightened around the wheel of the motor, which added more friction which could lift a bigger weight or deflect the needle of the Dillon Dynamometer.

It is basically a fancy fish scale !

The force, F, is measure in pounds (mass) at a distance, l, measured in feet (or inches) from the center of the motor shaft. Now you know where lb-ft (or ft-lb) comes from !

A mixture of things really. Some I get in storage lockers. Others I buy as lot in an auction.

I am usually interested in one or two items of a lot and then get rid of the rest. However, when I see names like Starrett I tend to hang on to it so that I can find out more.

Mon ebay you look under "sold and closed auctions ".

Not true. You look under "sold" auctions only.

Looking at "closed" auctions shows auction that have ended but the item didn't always sell. That's worthless data.
