I have the longer version of this center column for my Feisol 3441T:
http://www.feisol.com/​picture/CC2807S.jpg (external link)

The bottom piece, along with that hook, unscrew from the column. The top is fixed. On my last trip, it broke off due to falling over in the wind when I wasn't around. I think combined with my ballhead hitting the ground, it put a lot of pressure and broke it off. It seemed to be attached by some kind of metal. As something to make it still usable, I bought some superglue and reattached it. It seems okay.

This part doesn't seem to be something you can buy on its own and if possible I'd rather avoid shipping it back for replacement/repair just due to cost associated with that.

Is there anything I can do to secure it more? Put a lot more glue around it? I just worry because I want to have full confidence in it, and combined with a ballhead+camera on top of it, I worry about the single point of failure. Would the glue damage the carbon fibre ("melt" it?)


Edit: I should mention - one of my biggest worries is having the column down (most of the time) and hanging my backpack from the weight hook. I'd hate for it to somehow apply enough downward/upward pressure to just pop that top piece off, which means everything risks falling.

I wouldn't trust my camera to a center column that's super glued together. Just by a new center column and be certain. They aren't that expensive. You can buy it from the manufacturer.

It seems for the 3441T the center column isn't available as a standalone purchase?

They had said to me:

I guarantee you that if we re-glue a spot, it will be stronger than straight out of production ... much like a bone almost never breaking twice in the same spot.

It is entirely possible to be able to reliably make that statement. As a manufacturer they know they are working with carbon fiber and can properly select an adhesive based on that need. Cars are being built today where large carbon fiber panels are held in place by adhesives, usually made by Permabond.

Having said that, I see by a thread at https://www.geekzone.c​o.nz ...forumid=77&topicid=​183737 (external link) that an individual mentions a 3-year warranty in New Zealand. Is that a possible approach since I see you got the tripod in May 2015 and your profile shows New Zealand? If you have to do the repair yourself "super glue" is a type of cyanoacrylate adhesive, most of which turn brittle over time and then will fail. There are several in the marketplace that do not turn brittle, one being Gorilla Glue's Reinforced CA that is available in the States. They are not the best adhesive for carbon fiber but are adequate.

See if you can find a large "hobby" shop that deals in radio controlled cars, airplanes, and drones. Usually they have an abundance of good adhesives for carbon fiber. I would wait until such time as the current repair job seems to be failing (check frequently) rather than attempt to pull the column apart and create further damage.

I believe the center column in this kit is the same,. but I could be wrong :)

https://www.bhphotovid​eo.com ...Column_CT_3442_CCKi​t.html (external link)

I'm a lot less familiar with Feisol parts, but with Gitzo and Induro, as long as the series is the same, the diameters and thus the parts are interchangeable.
(eg: I can take the center column from a series 3 Induro travel tripod and use it in a series 3 Gitzo systematic rapid collar plate.)

I am interpretation the Feisol naming system to mean that all of these parts are series 3,.

Of course in Canada, I try to find a Canadian store with a good return policy before trying.

Nah, that's a different column. At least for the 3441T the center column is just a standard pole with 2 end caps...

Choose a suitable spot on the center column (close - but not too close to the break) where the carbon is undamaged. Score a marker line around the tubing making sure that is is square - a cheap Pipe Cutter does this nicely. The cut the tubing using the line as a guide - a simple hacksaw does a neat job. Tidy up with a file/sandpaper. Then remove the end piece from the off cut and clean it up. Make sure everything is grease/oil free and mix up some slow setting Epoxy Resin - I like Devcon as it flows a little batter than Araldite for jobs like this, though any decent Epoxy will do.

Apply the Epoxy thickly to the inside of the tubing and a bit thinner to the contact surface of the end piece. Make sure that you don't use so much that it will affect mounting studs/hooks etc. Then fit the end piece in the tubing and wrap a layer of insulating tape around it. Place the center column on end so that the glue flows towards the end that you are repairing. Double check that everything is square and leave it for 24 hours. Net result is as good as if not better than new.

I had a similar problem with a Gitzo 3 series center column which had been damaged just below the head mounting plate. I cut about n inch off the column and did the above. Took about 30 minutes + setting time and has been fine for the last 8 years or so. As for trusting it with a heavy lens? Well it's fine with the 800 F5.6 - currently Canon's heaviest lens and was fine with my earlier (and heavier) 600 F4 L IS Mk1.

Hope the above instructions make sense! If you lived in the UK I would just say post it and I will sort it.

Yes, the 3442 has a removable top plate, so to add a center column, one must also add the collar. There is no collar on the stock plate. Just a flat plate to mount a head.

I linked to the 3442 "kit" as I believe the center column in that kit is the same.
You would remove it from the collar and insert it into the built in collar on your 3441.

The only Feisol part I have is this;

...and despite all the other parts, the carbon column happens to be a 2 series center column. It will fit in pretty much any 2 series application, and can be removed from the rest of the assembly by unscrewing the bottom hook cap.

Awesome John. This is a great way to go.

My suggestion was the opposite of do it yourself, it's the "throw money at the problem" way.
Yours is a better way to go for anyone willing to roll up their sleeves.

Being a Gitzo, even an old one, the part is easily available - but pricey, more than I paid for the tripod!

The only hard bit was getting the cut end of the tubing square - I do not saw in straight lines!

I don't know about the US but a friend of mine found Feisol over here very helpful with queries and advice, perhaps an E Mail from the OP?

Perhaps if you had posted a picture of the center column that you DO want instead of a picture of the center column that you DON'T want it would make life easier.

Too bad to hear that it is not available as a standalone purchase. Would this metal machining services (external link) be of help?
This type of work isn't listed in their mechanical components category, but I think they can make something like that for you.
