granite,magnet, heightgauge I think, I will try it at work tonight, I have a lab to use see if I can do it, I hate height gauges lolHow would you do it with a height gauge?
I think I can attach to a magnet it weighs 36lbs on a granite top then touch off with height gauge then traverse up. I'm at work in the lab I will try it tonight and see, it may not work just an idea I will get back later see what happens I have 8 bushings with me, gonna see what happens lolHow would you do it with a height gauge?
Whidden doesn't produce bushings. They buy them from Custom Reloading Tools, (CRT).
Guys, the direction this thread has gone is absurd.
I agree, seeing as how the OP simply asked how to measure bushings, not how to control neck tension.
-
What difference does it make what the true bushing diameter is if it doesn't reduce the neck to a specific diameter?
That would be something you could ask the OP. After all, he asked about measuring bushings. For whatever crazy reason I chose to respond directly to his question. He never did indicate just why he wanted to measure true diameter.
But I can imagine one hypothetical where measuring diameters might be worthwhile: Suppose I had two or three different bushings all stamped the same nominal size, possibly from different manufacturers, or maybe just with or without TiN coating. It seems worthwhile to know how the bushings compare for diameter, so I could pre-sort them for subsequent neck sizing experimentation. For example, I might prefer to start with the largest bushing and work down in size. Just thinking outside the box here, you understand.
-
OK, how would you know which was larger to be able to do this? I think to be able to do this you would need to know the ID of the bushing.
Gosh. Ya think? Brilliant.

Maybe you need to quit blowing and give an intelligent answer.
-Pin gages only give "go / no- go" accuracy, but they're what I use.
It just occurred to me that Cerrosafe would work well, and then you can get a .0001" micrometer in play.
Cerrosafe shrinks after cooling.

Kinda funny quote-pin gauges give go or no go??
If my pin gauges are in .0001 increments, what does that mean?
It means your gages can measure to the nearest .0001". My gages are only in .001" increments, and therefore not very useful for the task.
You're free, of course, to question Cerrosafe's reliability, fair enough. But was my answer really unintelligent? (Intelligence is a trait applied to people, not words. Try "intelligible" or "coherent".)
You may well appreciate a chance to denigrate what Brownells publishes about Cerrosafe:
"Cerrosafe shrinks during the first 30 minutes of cooling and then at the end of an hour, is EXACTLY chamber size."
