What type of durability testing do you have planned?

Snohomish --

Thanks for your question, and your interest; it's appreciated.

I have already done a substantial amount of testing of the shaft -- and particularly the cam locks.  Specifically, a focus has been evaluation of the strength of the clamping capability of the cam lock (I've been very impressed).  I've been producing the lower rods for quite awhile now, and these will be included with the complete shaft system; over the past year of producing shafts, I have learned to have confidence in the tube suppliers I use; the tubes are of high strength and high quality. 

I am also having the shafts field-tested by a very well-known, very demanding detectorist.  He's both a land and a salt-water hunter, and he already uses my EQX lower rods.  He's providing feedback on the upper shaft now, as well.  One of the main questions he will be helping to answer is whether there is any benefit to adding the button holes (for the lower rod spring button) for heavy-surf hunters, and he'll be helping me to answer this question.  I am highly impressed with the clamping strength of the cam locks, but not being a surf hunter myself, I am seeking to determine -- in the demanding conditions that water drag and surf place on a coil/lower shaft from a torque perspective -- whether the inclusion of the button holes for such salt-water hunters might add additional security with respect to any potential for shaft twist.  (Of course, I WILL add those button holes for any customer who prefers them, for whatever reason).

Otherwise, I am highly confident in the design -- and as one additional point, I specifically chose cam locks that do NOT get epoxied onto the shaft, but instead are secured with clamping screws.  That way, if anyone were ever to have an issue with a cam lock for any reason, very simple/easy/inexpensive replacement could be done.  I also spec'd stainless steel for all screws/etc. -- to minimize any potential for oxidization/corrosion.

FINALLY, if you should every have an issue of any kind, with the shaft, I will personally see to it that it is taken care of in whatever way is necessary -- to your satisfaction.  To me, that's just a given -- I know of no other way to do business...

If you have additional questions, let me know; hopefully I have addressed your concerns!

Thanks!

Hi Steve,

The new shafts look great! I’m wondering if the lower rod that I’ve purchased from you, will work with the new shaft? I’m assuming it will. My apologies if this detail has been gone over already.

Thank you for letting us be part of the development process.

BH

BeachHunter -- absolutely.  The same lower rods will be used with the complete shaft system, as the one you purchased.  The upper has been designed around the already-existing lower rods, for that reason.  I will be offering the option for anyone who already has a lower rod, to purchase the upper shaft only (with appropriate price reduction, of course) -- if they so desire.

THANKS for your business, and your interest in the complete shaft!

Steve

Sorry I guess I was mistaken about the hex bolt and thumb bolt for tension on the clamp.  

However if the hex bolt is the same size as the control unit bolts that are used to clamp on to the upper shaft that would be awesome.  Then you could tighten and adjust everything with just one Allen wrench.

I can't recall, for sure.  I THINK (trying to remember) that the hex (Allen) bolts on the bottom of the EQX handle are 3mm, the bolts on the cam lock I did NOT choose are 3mm, but the ones on the cam lock I DID choose are 4mm...

Pax,

Thanks for your interest!  I appreciate it!

Lower rods can be ordered now; I have some in stock and ready.  I can get you my PayPal address if you would like to order.

 The complete shafts are not quite available yet.  I will be placing the order for the first batch of parts/supplies in 1-2 days; I expect 3-4 weeks for delivery of those parts, and then I should have the first of the shafts assembled and ready to start shipping with a week or so after that.  So figure 4-5 weeks from now; i.e. roughly mid January.  

I will put up “for sale” ads on the forums, and announce the complete shafts on my website and Facebook page, when they are ready.  So, you can either wait until then to order the lower rods you need, OR you can order lower rods now, and the upper shaft later — whatever works best for you!

Thanks again for your interest!!

      Hi all!

      I wanted to mention several things that may be of interest.

      First of all, as some know, I've been working on making colored shafts available regularly, as a "special order" item. I recently ordered a "test batch" of colored tubes, and all of the colored shafts produced from these tubes have been sold, except one -- it's in the "red/black" color, and I will post a picture of it a bit later.

      Second, I have several customers requesting colored shafts, so I'm looking to put together a new order for colored tubes from my supplier, in the next week to 10 days or so. I would like to get as many customers as are interested, to let me know, as my supplier would like as a large of an order as possible. So, IF YOU ARE INTERESTED IN A COLORED SHAFT, please let me know. Here is a picture of the available colors...

      Finally, I just received parts that will allow me to re-stock inventory on the standard (black) Equinox complete shafts; I also have CTX 3030 lower rods, and Equinox lower rods, available as well. Please let me know if you are interested -- sending me an email is the best way to get in touch, at steve@stevesdetectorrods.com.

      THANKS!

      Just by coincidence, this 25mm * 23mm carbon fiber tube fits both models, so it's a "win win".  I needed a 1" * 7/8" tubing clamp to make the conversion complete.  I didn't want to drill a bunch of holes and not have them line up, so I used the "GM 1000 clamp on" cuff.  As you can see, I trimmed off about 4" of the mid EQX section.  I wrapped sand paper around the cf tube and slowly increased the clearance in the handle/clamp combo, until I was happy with the fit.  Total un-extended length is 25", and could be less if you remove the coil.  
      As for the counter-balance weights, it's just another happy coincidence.  The washers fit like a glove (.90"), and by adding an over-sized washer, I can move the weight in or out of the shaft.  That 1.5" bolt with 14 washers weighs about 4 ounces, and is infinitely adjustable with regards to length, weight, and positioning.

      I have had a 600 for over a year now.  There is much to like about the detector; however, the ergonomics are something of a problem.  Unlike all my other detectors, I must use the Equinox arm strap, otherwise my arm will not stay within the arm cuff while swinging the detector.
      My original plan was to try to turn the middle rod into an S rod.  I wasn't sure I could do this with just bending, or, if it would be smarter to attach a separate S section either mechanically, via welding, or even via epoxy.  Since then, I have acquired two additional middle rods, one for each coil.  This would now mean three times the work if I alter the middle rod.
      The other day I was looking at my AKA Signum MFD.  It has the older style plastic housing.  Rather than being a straight rod, or an S rod, it is more of a V setup.  This got me thinking that if I bend the upper rod of the Equinox so that the arm cuff is higher, (similar to a hockey stick) this may solve the ergonomic problem, or, at least let me get rid of the arm strap.
      Has anyone tried bending their Equinox shaft?  Will a simple conduit bender be sufficient to do the job?

      Hi all!
      I just wanted to let everyone know that I have finally been able to kick into shaft production mode, after the last of the long-awaited parts shipment arrived last Wednesday.  Shaft building has been underway since, and I'm happy to say that I've managed to start shipping a first handful of shafts to customers on the wait list.  
      Everyone who has contacted me in the past, and had their name added to the wait list requesting a shaft from the "first batch," has been contacted; each of these customers' shafts are compete -- and are now in the midst of a few days worth of epoxy-cure time.  I expect all customers on the wait list, who requested a shaft from the first batch and have been contacted within the past week, will have their shafts ready to ship by Wendesday or Thursday.
      MEANWHILE, I have more than enough parts to build a couple of dozen shafts beyond those allocated to customers currently on my wait list.  So, if you are interested in purchasing a shaft, please contact me, or be on the lookout for a "for sale" ad in the classified forum later this week.
      Finally, I have typed up a couple of detailed documents as well -- one providing lots of information on the counterweights (including assistance/advice on how to choose the "right" length/weight for your personal needs), and then a second document discussing the "spring button hole" option that is being offered, for those who feel they may wish to still utilize the spring button in the lower shaft.  
      Please contact me if you would like to receive either or both of these two documents, or if you have any other questions regarding the new, complete carbon-fiber shafts now available for your Minelab Equinox! 
      THANKS!

      One of these days I am anticipating getting the V4 update for the XP Deus and along with that the new 4.7" x 9.5" DD coil. This should be a great coil not only for better "see through" capability is thick trash but a very good prospecting coil. The V4 update is supposed to include the ability to use 15, 30, and 45 kHz but only with new coils designed to operate at those frequencies. The 4.7" x 9.5" coil is the first of the coils designed to work at the higher frequencies. The Deus running at 40 kHz with this new coil should be a formidable gold prospecting device for trashy locations in particular.
      I did not want to have to swap my 11" coil around with the new coil and XP rod assemblies are a bit pricey. The full rod assembly is $264 and just the lower rod is $57.00
      I had heard about the Golden Mask Universal Rod Assembly for sale at on eBay for about US$120 plus US$30 shipping from Bulgaria so ordered one on May 31 and it arrived today just over two weeks later. There was no issue buying the item and the seller answered questions promptly. That seller is gone now so here is a link to the manufacturer website.
      The bottom line is the rod is much higher quality than I imagined it would be. The tubes are carbon fiber. The armrest assembly looks like cheap plastic in the photos but is powder coated metal. The rod locking rings have rubber grip surfaces and are some of the best I have ever felt. The unit collapses to 21" and expands to 55" with a weight of 1 lb 1.8 oz without the included armrest strap compared to XP rod assembly at 1 lb 0.4 oz also without arm strap. Slightly more weight but also more compact when collapsed. The end is 5/8" diameter and same bolt as the XP. The rod is just a tiny bit loose in the XP coil ears but will work. It is a hair tight on White's coils but also will work. It would be loose on most other brand coils and bolt too small. However, many lower rods will swap out with the lower rod on this unit so should be easy to mate up with most anything.
      I am very pleased with this purchase.

      Hi all.
      Now that I have the prototype shafts built, I've been able to work some more on the counterweight design, and I have moved very close to finalizing the design. 
      I have discovered through this extensive testing/design that the amount of weight needed to achieve proper counterbalance is a bit more than I was originally thinking, after the preliminary, "rough" proof-of-concept testing.  I would like to present the findings, and get some opinions -- from anyone who has been potentially interested in the counterbalance system -- as to whether these changes are acceptable, or if this would change your desire to possibly purchase the counterweights.
      1.  The weight needed to counterbalance the 12" x 15" coil, (based on an "average" lower rod extension length), is roughly 28 oz.  This is a fairly substantial amount of weight -- BUT -- I must note that when the weight is applied, the machine swings BEAUTIFULLY.  It FEELS lighter, even though the "absolute weight" -- i.e. according to measurement as provided by a scale -- is obviously greater.  With my forearm in the arm in the arm cuff, swinging the machine normally, I was literally able to hold the handle of the machine with only my thumb and index finger -- and swing the machine effortlessly!  The sensation is that the machine FLOATS across the ground!  (For the 11" coil, the amount of counterweight needed is of course slightly less -- roughly 25 oz.)
      2.  To include this amount of weight in the tube extensions, and yet not have the extensions excessively long, I must use larger-diameter carbon-fiber tube than I planned -- I've decided on 31mm outside diameter tubes.  I had intended to use the same diameter of tubing as used on the upper shaft (22.15mm outside diameter), but the extension length required was far too long.  
      3.  Using the 31mm outside diameter tube for the counterweights, I calculate that length of the tube extending beyond the end of the shaft will be 7 1/2" for the 12" x 15" coil, and 6 1/2" for the 11" coil.  
      4.  There would be no changes to the shaft design needed; anyone wanting the counterweight system in the future would still purchase a shaft with the same threaded female fitting installed in the butt end of the shaft, and the same threaded end cap that screws into the butt end.  The only changes would be to the counterweights themselves (as comparted to what I had originally planned) -- i.e. larger diameter carbon-fiber tubing, and thus a larger end cap for the ends of the counterweights themselves.
      SO, my questions are, with the counterweight lengths needed now a pretty-well "known quantity" -- i.e. 6 1/2" and 7 1/2" long (11" coil and 12" x 15" coil, respectively), and the weights to achieve balance being also a pretty-well "known quantity" -- i.e. 25 oz. and 28 oz., respectively, would those interested in the weights find these specs acceptable?  Please offer your comments.
      Preliminary/rough pricing info would be as follows.  One counterweight, $22.50 plus shipping ($30 total).  If an EQX user only wanted to order one weight, I would suggest the 6 1/2" long, 25 oz. weight, designed for the 11" coil; this amount of counterweight still achieves a degree of balance that feels GREAT with the 12" x 15" coil.  I am of the opinion that no counterweight is needed, for the 6" coil.  Two counterweights, one for the 11" coil and one for the 12" x 15" coil, $42.50 plus shipping ($50 total).  
      Thoughts?
      Steve
