Topic: stand and stereo bar thread adapters

[Krispy D]

Not sure if this is the right forum but here goes.

Does anybody know the thread standards used on light stands and stereo bars?  I know there are two or three standards.  I have two stands both of which have small threaded studs (3/8 maybe).  I have an AKG? stereo bar (the one with two articulations) and I have a shure vert bar.  The AKG bar has two adapters in it.  one larger one and then a smaller one that fits my stand.  That one is almost shot (it is anything but stable).  and the sure vert bar has an adapter in it but it doesn't get small enough.  I want to go online and buy adapters for both bars so I don't have to swap back and forth, I also run two rigs sometimes so I need them both to work at the same time.

Does anybody know what these standards are so I can quickly jump on line and pick up what I need?

thanks

nice!  thanks Moke.  So 3/8, 1/4, and 5/8.  Is a standard mic clip 5/8" then?  that's what both the vert bar and the stereo bar are.  If that is the case I know my stands are both the smallest available so I would need two 5/8 OD to 3/8 ID adapters right?

If your stand has a 5/8" stud (no threads) tip (some of which also include a 1/4"-20 thread on the end), consider a Bogen 5/8" stud | 3/8" male thread Rapidapter and a 3/8" > 5/8" thread adapter.  The Rapidapter makes for easy/swift on/off.

I have one of the ebay speacial amvona dynatran stands.  It has a threaded end on the top looks like about 1/4 inch but I have not measured it.

I finally got on of those Dynatran stands off eBay today! Been trying for weeks and kept getting outbidded, probably because I was trying to get it as cheap as possible. Got in today at $15.01. I hope with the $16 plus shipping it arrives yesterday! rWc3523

Hey Russ,

Have you looked at "Bid Assistant" or the like at your my ebay page?   Also on the product page if you have watched the item.........  Low bids by your selection until you win or run out of selections.

Actually, I haven't I figured someone was using a sniping program to cut me out at the last second, which is what I try to do manually! Part of the problem was inattentiveness on my part and missing the end of the auction! But I'm cool now. rWc3523

I have one of the amvona stands.  The stud/threaded end combo was too long to satisfactorily accept the Bogen adapter. The metal of the stud was surprisingly soft and I cut the threaded end of the stud off with a hack saw.  This left a sufficiently long 5/8" stud to easily attached the Bogen adapter.

So I built a couple of adapters this weekend.  they came out quite nice.  They are 1 1/4 inch long with male 5/8" 27 tpi threads on the outside and female 1/4" 20 tpi threads on the inside.  work like a charm and cost me $0.00 ( I had a couple feet of 5/8 aluminum stock floating around from a previous project) And only took about 10 minutes to build.

I have been thinking of making a few of these myself. Did you use a die for the 5/8 - 27 threads or cut them in a lathe?

used a die but did it all on the lathe.  if you don't have a lathe at your disposal any small machine shop should be able to do it for next to nothing.  It literally took me about 20 minutes

Cool, I'll have to make a couple of these. I work as automation tech in a large machine shop, finding a lathe shouldn't be a problem.   

Any leads on a reasonably priced 5/8-27 tap. All the ones I've come across are over $50! Don't need high quality, I'd only be cutting 6/6 nylon or aluminum.

Not really,  My father in law owns a full service machine shop so I do everything there with all his tooling.  I can tell you that Harborfreight is a decent resource for cheap tools you don't care about.  Let me openly say that I am a big advocate of good tools that last over cheap tools that don't but for the best price on "use it once" kind of stuff check them out.

I'm all about quality when it comes to tools, but in this case HF quality will do. I have my doubts that harbor freight will have that thread pitch though, it is kind of a bastard size.

If we weren't so busy at work I'd just have one of the guys make me one.

When I get my hands on one I'll let you know, in case you ever want to borrow it.
