If you really want to punish yourself look at the winning bid price!

[Chopper]

I thought I was the bastard that stuffed ya weekend Chop.

[ratshot]

Nah Chop it would take more than that hickup to piss me off , anyway that was a top last target to take the glass ware. Congrates.

[RDavies]

You would think that there would be some Chinese knock offs of the ICC machines by now, given the price people are asking for them.

[Cameron Mc]

Rod, I know of someone in oz working on building these.

They do really work

Stay tuned

I'd be interested in assisting said individual in getting prototype up and running. I do have some experience using thickness measurement probes for electroplating in 0.001mm range.

Send my details to your contact and have them contact me.

So what would the retail price of this gizmo be, if you could buy one here in Oz ?
Being a good Queenslander, Cameron will buy one next year when he shoots in the States, and will loan it for free to everyone North of the border.

[johnk]

.... except that they aren't made any more.

[Cameron Mc]

John is correct, the Juenke is not made anymore.

Tony mine is locked away somewhere, I have forgotten where

Aaron, I will call you on the weekend.

I've estimated about $2000 breaking even using available parts, but you have to find someone with a passion to do it for that. Vern obviously had passion for accuracy and you can't put a figure on that. Some of us would give the products away but the wife would never forgive us...if it was a painting it would be hanging in the Louvre.

So how many are there in aus i know off 3 at least

[Daniel Chisholm]

Can somebody explain to me either or both of the following:
- what a Juenke machine measures
- how it makes this measurement.

I've seen one, and have seen it used. It has to do with sorting/selecting/assessing bullet quality. By measuring (by means unknown) of an important (but unknown) bullet parameter. I've never had a straight-up answer or claim as to what the machine is allegedly measuring.... I can make various guesses:
- jacket thickness
- core density/uniformity/voids/faults
- ultrasonic? resistive? RF?

[aaronraad]

Here are two resources for information regarding the measurement system:

and


http://www.bulletinspector.com/...you know this is serious when you need to be an 'electrical engineer or equivalent experience' to assembly the kit in a working order.

Also here is a pretty good description off the LRH forum: http://www.longrangehunting.com/forums/f19/juenke-i-c-c-3796/index4.html If you can't get access to the forum link send me a PM or email and I'll send you a PDF print of the page.

I'm leaning more towards an eddy current sensor.

X-ray/radar frequency analysis would be more definitive, but you need to be registered for such a device with your State's Health Department. Dentists have been known to make use of their X-ray machines for checking bullets, dies and anything else they can fit into their small units.
