I have a Bogen Manfrotto 3051 tripod and the Bogen BG3052 extension leg set kit for it. I installed the extension leg set back in 2006 but cannot find the instructions for the kit. Does anybody have the instructions for the BG3052 extension leg set?

Just as a little background, the Bogen Manfrotto 3051 tripod (supposedly the same as the Manfrotto 068) has three fixed-length legs that are a nominal 35mm outside diameter. Each of these legs has a nominal 25mm diameter sliding leg inside them.

The BG3052 extension leg set has three replacement 25mm diameter legs, each with a sliding leg inside them which is a nominal 20mm diameter.

What I cannot figure out is how the 25mm diameter sliding legs are removed and installed into the 35mm legs. I have the extension leg set installed but would like to be able to restore the 3051 tripod to its original configuration if I were to sell it.

Thanks.

Here is a place to start, They do seem to know a lot about Bogen:

Supposedly the Manfrotto 058 is the same so the parts diagram at https://www.manfrottos​pares.com/058b-parts.html might be useful.

I've had that drawing and a few others for similar models but none of them go through how to remove the sliding legs from the legs that are attached to the spider.

I had a long chat with the tech at Spartan Photo Center in South Carolina (I was directed there by a person at Manfrotto) and even he had no clue how to take it apart.

The parts I need to know about are not carried by this vendor and are not even detailed on the parts sheet at Manfrotto.

Thanks anyhow.

can you post a couple of photos of it?
looking at the pretty average images in google, it's likely just a matter of taking the feet off, then undoing each leg-lock from the tube it's attached to, then finally loosening the leg-locks up by the spider.

best shot I could find of what I think you have (not my image)

I've had the legs off my 055prob a few times for cleaning and it didn't seem difficult. (leg-locks are probably different though)

The leg locks are internal - unlike most Manfrotto tripods (like my 3021 and your 055 with flip locks). There are levers just under the spider - one for each leg and another that loosens all three legs at once - that activate rods inside the legs that push on spring-loaded brakes. My problem is not knowing exactly how the rods are assembled inside the legs. I need to know that so I would not mess something up if I just charged forward.

I'll try to find some time to photograph parts of the tripod close up. The photo you posted is similar to what's on the bottom of mine but, as I said, it's really important to figure out how all the stuff that's inside the leg comes apart and goes back together.

Perhaps of some help.

I found this content at http://www.ebay.ca ...425?hash=item3f801f​b5b1:gWcAAOSw~e5ZTWQE

I've also attached some close-ups of the leg ends. Seeing things might help in getting ideas from others.

One thing I remember from many years ago working with Manfrotto parts is sometimes to loosen something at one end requires an approach from the other end. On a center column I once worked with, to remove the top, you used a socket and a very long extension but approached an internal nut from the bottom end. This was not obvious unless you removed the bottom end and looked inside the rather long center (probably 15 inches) column.

There is also an interesting 5-year old thread on this tripod at https://www.cloudynigh​ts.com ...-this-bogen-tripod/page-2. From reply #38 on the discussion is about the leg extensions. Perhaps if you joined the forum you could PM some of the contributors that seem to have knowledge of the extensions.

Thanks, John. Unfortunately, none of those sources come close to answering my question. I might give the other forum a try, though.

The extension kit that I bought several years ago and installed on my tripod (still installed) are a two-section affair (each of three extensions is a 25mm OD tube with a 20mm tube inside it and a foot is mounted to the 20mm tube). The original (25mmOD) sliding legs must first be removed from the largest (35mm OD) legs and then the new extensions replace the original 22mm tubes. The problem I have is that the 25mm tube does not simply slide out of the 35mm tube. I've lost the instructions that came with the extension kit. That would show all I need to swap the extension kits for the original 25mm legs (which I still have).

Could these be 3rd party extensions? All the pictures I see on line seem to be a one piece and are often referred to as 19 inches in length.

They were definitely Manfrotto parts according to the receipt from Adorama.

Apparently there were two different types of extensions made and the choice seems to have had to do with the foot hardware at the bottom of the original sliding (25mm OD) legs.

Any chance Helen O. could help out? Adorama might have a manual on file.

I have not tried asking her. Might be the best idea yet.

surprised she has not answered already - must be on holiday!
