DV7000 tripod locking screws for legs and for central, extending column are missing, where can I get replacements

Hi Stefan
Possibly some bad news for you..., the Part #R190,304 you ordered is not made for the #190XB tripod..., it is for a model several years older (though it MAY fit)..., (see link for correct parts diagram)!!!!
http://www.manfrottospares.com/download/pdfs/190XB_20061025.pdf
To easiest way to replace one of the top leg castings is to first remove the centre column and then support the tripod in such a way that the (3) legs are not touching the ground (i.e.: all the weight is supported by the casting through which the centre column would normally mount. You will then need to undo the (3) screw (allen key style) that pierce this casting...., (the reason for wanting to support the tripod via the bottom of this casting is that all the small parts SHOULD stay in place when the top casting is separated from the lower casting. Once this has been done..., carefully remove the leg with the damaged top casting...., replace it (making sure the new one is facing the right direction) & then reverse the procedure.

Hope this helps

-It is possible that you are overloading the tripod, thus causing this problem (check specs on tripod model)
HOWEVER IF YOU AREN'T....Giotto uses (2) different leg lock designs..., quick release (normally adjusted by a socket wrench) or rotary (screw locks)!
- If tripod uses screw locks, sometimes foreign material gets into the mechanism and either damages it or prohibits from tightening!!!!!
Note: rotary locks are easy to maintain & if you need parts..., they are user replaceable and usually inexpensive! (contact Giottos distributor in the country you live in)!!!
BUT FIRST!!!! (often problem is caused by dirty lock mechanism)
-carefully unscrew the leg lock (that is slipping) until it separates from the leg higher leg section & carefully pull out the lower tube (at the top of the lower tube will be 'shims' that are part of the lock mechanism).
-Look closely at existing 'shims' do they show signs of cracking, of a build up of dirt, etc. (if damaged they will need to be replaced)
-if shims are undamaged..., use rubbing alcohol & a clean cloth to clean shims and both the tube they sit on and the inside of the tube they slide into.
-once both sides of the tubes and both male & female threads of the locking mechanism are cleaned..., place a light coating of a light oil into the threads (sewing machine oil, bike chain oil, etc)...., do not get oil on the shims!!!!!
-replace locking shims back into position and carefully slide leg tube back into place..., then screw locking collar on (this should not take any force..., if while threading lock collar back on..., it seems tight..., back off collar and check positioning of shims). Repeat procedure!!!
TEST RESULTS!!!
Note: in most cases with rotary locks, problem is purely a maintenance issue, cleaning usually fixes the issue!!!

-If you are looking for a compact light weight (CF) tripod for video...., that is going to be...., stable & durable (for use with a smaller video camera or a DSLR) & with a mid-level spreader...., I have some bad news for you. They do not exist!!!!!
-You can get a number of tripods that meet some of these requirements..., but not all!!!
-No fear....., it is still possible to get a tripod that is small, light, repairable and with a higher weight capacity and better durability than either of the Manfrotto tripods you mentioned..., but they will not use a mid-level spreader!!!

-Questions for you...., the manfrotto #055CXB has a column that terminates with a flat plate & a 3/8-16" thread. The Manfrotto # MTV502AM tripod has a 75mm bowl mount. Do you use a video head with a flat base or with a 'bowl'?
-If your head has a flat base consider looking at CF tripods from brands such as Sirui (#N2204 or #N3204)..., great value tripod from China..., or products from Gitzo or Really Right Stuff...., (superior products...., and your grandkids will be using them..., but pricey)!!!!
-If your head uses a 75mm bowl mount get the Miller #1501 tripod...., stupidly strong and well supported.

-Bottom line..., with light to mid weight cameras, if you go with a good quality spreaderless tripod that uses 'rotary locks' vs 'quick release' locks...., the leg mechanisms are so superior that you will find that you will get less flex than most tripods with spreaders. They will also be smaller, lighter and allow you to shoot far closer to the ground!!!

Go t a shop that has a good selection of quality tripods and test for leg twist..., you will be converted!!! (note: to test this leg flex..., extend the legs & grab hold of (2) of the tubes near the top 'crown' and then try to move the legs to the left then right...., many will exibit significant flex at the joints!!!!

Raise the center column all the way up. Under the head next to the center column are at least 2 or 3 screws. Back them out uing a meduim slotted screw driver. The head should then screw off.

Hi I need a locking clip for one of the Velbon Tripod legs any suggestions?

cheers

if you have lost a srew or wing nut, it will be loose where there should be one. set it up and then try to raise or move it around in one spot. iof it moves than look for a screw hole. the handle itself sets the rotation try unloosing the handle..

I did not have any luck in locating the leg locking assembly for my Vivitar V3000. Instead, I plastic welded both that were broken on mine. So far, so good!

take it apart, there is a rubber ring like a belt or rubber band, either broken or missing. you will have to find a relacement for that, may have to take apart another leg to have one to compare, course I don't honestly know where you will find that piece. too take it apart just keep spinning the lock counterclockwise until it comes off. good luck.
