We'll see if that title gets changed. I've been here more than ten years, I'm entitled to a little fun now and then aren't I?

Anyway, I bought a used gini rig from a friend, but it didn't come with the screw to mount the rig the bottom of a camera. It is so hard to describe WHICH screw I need I thought I'd just upload a pic so you can see the mount on the rig plate. It's one of these weird proprietary screws that goes up through the bottom of the rig plate, through, and then into the 1/4 20 threads on cam.

What is this called and where do I buy it? Does anyone sell them in Houston? It would also be nice to get more of those little tiny screws that go into the secondary/very small hole on the cam bottom to keep it from pivoting (like the ones on a tripod plate). Same question. . .what is that called and where do I find it? I emailed gini rig and they decided not to get back to me ever.

Hi Josh, I hope they don't change the name of your thread.

I've heard it referred to as an anti-twist pin. Sachtler calls them a video locating screw.

I'm not sure if each company uses a different size and pitch but the best thing to do would be to bring the plate down to your local hardware store and find the right size by just trying a bunch of different screws. Once you do that you'll know the exact size to look for. If it were me, I'd just get the appropriate size steel dowel and break out the tap and die set and make my own. But, I'm a big DIY person. If you're not maybe one of your friends is an could do it for you.

Yeah, sorry, not a DIYer.

It has a very large "base"screwy part, about the size of a nickel or something. the small piece would probably be identical to what's in a sachtler plate (like my DV4 plate for instance).

Sorry Josh. I misunderstood which one you were talking about. If it's the actual one that goes into the 1/4 x 20 in the camera I would search for Camera Fixing Screw. I heard that Gini Rig is using a 10-24 screw instead of the almost universal 1/4 x 20 or 3/8 screws used on most video and camera equipment. You might try some place on the internet like this Shoulder bolts, Allen, Alloy steel black oil finish, 1/4" shoulder (#10-24 thread) - Bolt Depot (http://www.boltdepot.com/Shoulder_bolts_Allen_Alloy_steel_black_oil_finish_1_4_shoulder_%2810-24_thread%29.aspx) that specialized in odd sized screws.

There use to be one shop out around me that was called the Srew Shop. The only carried fasteners of all types sizes and shapes. It was the only brick and mortar place like it for 300 miles and I was in there about every other week. Unfortunately the old man that ran it decided to retire and no one wanted to take over. Now when I need a really unique screw I have to either hunt on line and pray that it will work or manufacture my own.

Good luck. Sometimes finding the right screw is like finding a needle in a hay stack.

Just checking..........working from top left to bottom right in the pic, are we, er, you, talking about hole 2 and/ or 4 or something else?

That notwithstanding, if said screw is designed to go into the butt of a video camera, it must, by definition, be either 1/4" X 20 or 3/8" X 16 or two of the latter OR even one of each.

Try a bog standard 1/4" X 20 out of any QR plate to hand and see what happens, the actual plate looks pretty similar thickness to a QR plate, so it may be that simple.

It would be the two larger holes in the picture.
(the pin/tiny one would screw into the OTHER side of the plate on the other side and be a permanent fixture. . . unless it got in the way of mounting the cam 'cause the cam only had one hole.)
That's true, about the size. I guess I always think of 1/4 20 'cause it's the "safe" one that all the cams I'd be likely to use have, while not every has the 3/8.

Something like this:

6mm Thread Depth 1 4" D Ring Screw FOR Camera Tripod Monopod Quick QR | eBay (http://www.ebay.com.au/itm/6mm-Thread-Depth-1-4-D-Ring-Screw-for-Camera-Tripod-Monopod-Quick-QR-/390761562037?pt=LH_DefaultDomain_15&hash=item5afb343fb5&_uhb=1)

?

Yes, I agree, a little fun is indeed warranted.

Looks close, hard to tell what threads look like from that angle or how thick/wide/diameter that base is. As I said, the correct screw should have a base about the size of a nickel.

Josh, take the plate go to a Home Depot store and in the hardware section where the nuts and bolts are they have a piece that has all different sizes and threads of screws and bolts. You can twist the plate on to the sample and at least you'll know what size thread you need then you should be able to find the proper screw or at least something close enough to work.

If thats what i have to do thats what i have to do. I will try calling gini again and see if they can assist first.

Gentlemen, I'm a moron.

My CAVISION rig I had looked like it had the same kind of setup, and it used the weird large screw. However, I noticed that the recessed hole in the gini rig appears to be the exact same diameter as the one in my tiny sachtler plate, for my DV4 tripod, which leads me to believe it takes the exact same sized screw. So it's a typical 1/4 20 tripod plate screw for screwing plate into cam. So I'm a dumb dumb.

Edit: tested gini rig with the screw from sachtler plate--- gini plate must be a little thicker 'cause there is less of threaded part of screw sticking out on top than with sachtler plate. Thinking I need a longer version of the tie down screw. I was going to order these:

If too long can use washers.

Still need the little teeny tiny screw whose head actually goes up into the camera bottom (non-threaded, keeps cam from pivoting). The video locating pin/screw, as someone mentioned above. Can it be gotten without buying a $70 sactler plate as well?

I somehow lost the "VHS" pin (that's one name for it-don't ask me where it came from) on a Manfrotto QR plate. I dug thru my pile of stuff and found a small threaded screw that fit the recess in the bottom of the camera, was able to screw it into the hole in the plate so it didn't get lost and BAM! fixed. As long as it's small enough to fit the recess in the camera and fit thru the hole in the plate you don't need anything special.

Fair enough. Ill see if sachtler deigns to respond to me. If not, then off to the depot.

Hmm, well, guess I won't comment on your opening statement except that "many a true word spoken in jest" springs to mind.

To the chase:

All 1/4" X 20 photo/ video screws are not created equal. Some, to put this a delicately as I can, are, quite frankly, bigger than others, it's that simple.

Just like human genetics, what you get is what you got, end of story, but they all seem to get the basic job done, regardless.

As for you VHS pin (for such it is called) problem, hmm, you may find, if you can discover the appropriate thread type to match the available threaded hole, that the threaded end actually fits the available orifice in the camera.

That VHS pins do not usually have threads to fit said orifice is unsurprising, as said hole has no threads with which they could engage. Irrelevant, as long as said VHS screw prevents the camera revolving about its single 1/4" X 20 retaining screw in use.

If it fits, use it. If it don't, back to the drawing board.

yes. if sachtler doesnt answer i know the hardware store has these weird double threaded screws that have no head and are threaded at both ends. something like that might work as a vhs pin if its small enough.

Hey. If anyones interested, heres the sachtler part number for the mysterious vhs pin/video locator pin

Going to state the obvious: Almost every pro tripod head comes with spare screws. Usually one of each of the two standard sizes. Those extra screws are often screwed into the bottom side of the head. They may appear to be functional parts, but they are not. They are screwed in just for storage. Have you looked at the bottom of every tripod head you have around? You might find an Easter egg!

I am not one of those guys that immediately sells old stuff on E-bay. It goes into my AV bone yard. I dig up useful old bones there all the time. Maybe you have the screw. Just asking?

Josh Bass

Nah, definitely no spares. Plus theyre for a gini rig, not my tripod. So definitely no spares.

I figured as much...just asking, I know the screw you're looking for is not standard tripod, but close....I can't be the only one with a pile of old junk laying around I get parts from...

Im an idiot. I just realized what you meant. I will look when i get home. There may well be some extras i thought were parts of the head. Intriguing.

Unbelievable... the thread title actually fits, so it stays in place. A rarity for Josh Bass? Could be.

I've been working on something for a while and discovered to my dismay that not all camera screws are the same. It's a very subtle relationship between the depth of the tripod plate and the hole depth that you want to go into and the many camera screws I've tried have had a problem with one or the other in that the length of the actual shaft is too long so it wont tighten up on the camera. In fact I've heard of people actually going through the bottom of the camera trying to tighten the wrong length of screw up.

In the end, for the product I've been working on I got them made to measure to a similar standard (but not exactly the same) as Sachtler and this has solved my problem.

Josh Bass

I ordered the slightly longer than typical ones I linked to above, since the one in my tiny Sachtler plate seemed a wee bit short. If it's too long I can always use washers.

PS Gini-rig never got back to me after two emails. Cavision, on the other hand, who doesn't even make the rig I have, but I asked them because they seemed similar, got back to me within a day.
