Question on transit tripods
Anyone know if there is a standard for transit tripod sockets where the
transit attaches? (forgive if my terminology is not correct) I've been toying with an idea for a massive and rigid ball head for my new camera when I stumbled across the Burzynski ballhead. Very much what I was toying with, so I know my concept is valid. Further looking at that head reveals it's one of the most rigid ball heads made, which of course exposes the next weakest link, the tripod. While carbon fiber tripods are certainly rigid and light, they are very expensive. Some folks seem to favor wooden tripods based on those used for surveyors transits, saying wood absorbs vibration as well as just about anything. Well, I can't afford any of those tripods either. So thinking about looking for a used surveyors transit tripod. I can make to fit whatever I buy of course. I'm pretty sure there are proprietary mounts out there, but hoping there's one that has become an industry standard. This would make it easier to upgrade to a nicer tripod should I decide to do so. This btw, is not going to be a tripod for hiking all over creation, it's going to be pretty heavy. But it'll also be nice and rigid... Jon |

Jon I have an old brass Craftsman transit with apparently an 11/16" - 27 mounting thread, slightly larger than the 5/8"-27 thread of a microphone stand. The owner had driven over the tripod and threw it away. Google gives several standards. 5/8"-11 seems common. jsw |

The surveyor who lived in my house before me left an old tripod and you can have it for the postage cost if you like. It has a 1" long, 1/2-5/8" tapered mount, telescoping legs, and half a black crinkle-paint finish left on the top section. There is no bracing, but that's easy enough to fab up. It's 2 lb 10 oz without packing. New tripods appear to have a 5/8"-11 stud mount. There's a screw in the top of this one, so it may be replaceable. -- Win first, Fight later. --martial principle of the Samurai |

Jon You'll find lots of info on using transit tripods if you search for DIY telescope tripods. People have used surveying tripods from Goodwill or whatever, crafted their own from beautiful wood, or hammered together some 2x4s etc. |

Jon I've got a Majestic tripod for the heavies, has a geared head. $40 at the local camera swap. Weighs in at 15 lbs. Had been hacked about over the years, nasty leg tips, crummy cheap fastener replacements. Still being made(but not for $40). See www.bencher.com. They're out there, sometimes for pretty cheap, all metal, U.S.-made. Had at least a dozen at the swap. The local college AV guys are getting rid of them. Have seen them on camera swap sites, too. Would be a better deal than trying to modify something not meant for photo use. Had to straighten the worm wheel shaft on the gear head and regrease, replaced most of the cheap fasteners with some decent stuff and waxed up the telescoping legs. Works great now. Originally had a three-way level on it, that's missing. Extends up to about 8-9'. As a plus, when I replaced the leg tips with some decent rubber ones, I found several sets that would fit into my Husky tripod dolly, So it can be wheeled around now. And it makes a great mount for the giant binoculars. Bencher has several different platform types for the gear head, too. Stan |

As for a really good tripod, take a look at the Quickset line. http://www.quickset.com/products-tec...rable-tripods/ They are very well built...cough..cough..I have seen them used for car jacks in the military. ;) Used, their pricing are within the realm of us mortals. Check Ebay, large format photo and astronomy sale sites for used ones. TMT |

I'm pretty sure there are proprietary mounts out there, but hoping there's one that has become an industry standard. This would make it easier to upgrade to a nicer tripod should I decide to do so. Transits typically use a large (3.5"-4" or so) threaded mount so there can be a hole in the top of the tripod (the threads are on an open ring) to allow the plumb-bob to be connected directly to the transit. I'm not really sure what that size typically is, or how many variants there may be - in both the instances I have experience with, the transit and tripod have lived as a set, and not been interchanged with anything. In the age of total stations (the fancy laser range-finder devices virtually all real surveyors use these days, since they are much faster and probably more accurate) this may be more of a historical tid-bit than directly relevant (my understanding is the total station does not need to be set in any particular spot, so a plumb bob is not needed.) Some tripods provide a way to mount something on a small thread as well as the large ring thread. If you find one new enough to not be marked up for antique value (ie, not brass) you might well be able to get the matching threads and a really nice turntable by butchering the obsolete instrument you can get with the tripod, but may folks pretend they still have values based on what they used to cost (heck, some places still sell the things new, god only knows why at this point.) I've had my current powder-coated Japanese-built German-branded unit on loan for the better part of 20 years from someone who switched to a total station and does not want the thing back, though I occasionally remind him I still have it. I myself find a laser level (and the leveling rod from the transit set) faster and more useful for much of what I used to use the transit to do (ie, not real transit work, things a dumpy level could have done.) -- Cats, coffee, chocolate...vices to live by Please don't feed the trolls.

Question on transit tripods
Thanks everyone for all the replies. I found the solution to my problem
in a German manufacturer of very nice wood tripods, Berlebach. Can't afford to buy a new one, but with patience I will score one of the models I'm interested in on eBay sooner or later, at a price I can afford. Jon |
