<p>Hi Mike.</p>
<p>These piqued my interest too.</p>
<p>I only found a supplier in Sweden(!!) with these in stock. The price is around $65 USD. EMG USA has little to no info on them so I presume they're discontinued. Now I'm kind of wondering 'why?'. It was either a design that didn't hold up (in the long run) for the majority of real-world players OR few players wanted to pay that much for an endpin jack.</p>

<p>Good info, Stephen.... they're sure new to me but the theory makes sense. I particularly like that they do the "minimum invasion" insofar as needed to rework whatever existing guitar they're going-into.</p>
<p>The extra conductors don't hurt, either. </p>
<p>I'll have to keep my eyes open for a source, as it can't hurt to have a couple of extra tricks in the bag for whatever rears it's head down the road. Thanks again :)</p>

<p>Mike I'm not sure if these are available anymore but they were well made and I installed many of them. It works by an allen screw at the base of the jack that when tightened from the OUTSIDE pushes the balls into the sides of the endblock. As long as the hole in the endblock was reasonably clean and straight they held well. The other benefit was that it is a 4 conductor jack that allowed 2 different signals, ground and battery shut off. I worked on some of Michael Hedges guitars in the early…</p>

<p>I really don't like those jacks. They fail inexplicably. The other one I don't like looks like this:</p>

<p>It seems like they should never fail, but they do. </p>

<p>Stephen... couldn't find much written about the EMG Ultrajack that differentiates it from other "long" jacks. </p>
<p>Does it have an expandable length to accommodate extra-thick tailblocks, or something else to solve the issue? Hmmm, do the small circles midway along the shaft have anything to do with holding it in place? Are they some sort of detent-balls that lock into a raceway?</p>
<p>Maybe I'm missing the obvious, but always open to new discoveries! …</p>

<p>Well, hot doggies!.... I'm swimming in <em>"reverse counterbore spot-facers"!</em> To back track: the job that brought me here (installing the jack in the too-thick tailblock) is out the door. </p>
<p>I used the 'Anderson' screw-in jack. The customer's happy, I got paid. It's done & gone.</p>

<p>In the meantime, once Frank supplied the proper nomenclature, I did some digging-around eBay and found a guy selling some used aircraft tooling... including 2 <em>"counterbore spotfacers". </em>Oh happy day. They were cheap enough and arrived this morning. They will definitely do the job, at least when (or if) the job ever surfaces again.</p>
<p>One is 5/8" and the other is 1". Both employ a unique attaching/detaching feature.... after the shaft gets inserted, a simple twist locks it in place loosely. When the bit is turned in the cutting direction, the bit locks down on the shaft and cuts. when the direction is reversed, the bit simply falls-off the shaft. Pretty ingenious. </p>
<p>Any number of makeshift bearings can be used to increase the diameter of the shaft to fit an existing hole, making the centering of the counterbore easy. Or the hole can be temporarily re-dowelled and drilled to fit... either way works.</p>
<p>And then Paul H. tells us about grinding the 1" spade bit and... all of a sudden... it's an embarrassment of riches! I had two 1" spade bits, so one became a dedicated counterbore when I removed the original point to facilitate handling.</p>
<p>Can't wait for the next job to rear it's ugly, 'cause I'm ready! </p>
