:rolleyes: Hi to everyone, First time posting. It seems some stabilizers do and others
don't have bearings within the curved pipe section where the arm's pin enters. If is that the case,
does it make much difference?

Hello Alexandre:
Why are you asking?
Someone offered you a gimbal without bearings? (just a joke!!)
Or trying to build one?
Did you visited the hbsboard.com?

Best regards from Buenos Aires (pretty close, eh?)
Good luck

Hey,

Perhaps you are refering to the arm post?? PRO and others have the bearings and the 3A type do not.

I just put the bearings on my 3A arm and love it!!

That is what I am refering to Charles. BTW does anyone know the specs of the bearings used within the curved pipe ?

Hi:
I´m curious, Did you add the bearings in the handle or in the arm (like the Steady Rig arm)?
In either case: Did you have the work done by a machinist or just replaced the part (wich part?) with an updated one?

Best regards
Alejandro

Hi Alejandro,

I intend to place bearings in both places. The gimbal was was done in a CNC. Btw. where do you live in Buenos Aires, I have some friends from there(River Plate supporters)

Hi Alexandre!!
I live in a neigbourhood near downtown.
Even dough I work every weekend on the transmissions of football matchs, I´m not a big fan of any team.

Regarding your gimbal, I don´t think is necesary to have bearings in both sides. This could be just a redundancy( did you visited the hbsboard.com site?).

Check out the steady rig site and check out the bearings in the pin of their arm.

Suerte rapaz!!
Agora vou embora ouvendo os paralamas do suceso, chao...

I would suggest that however you build it, also include a variable clamping setup that allows you to "dial in" the amount of free movement available at a given time. Not everyone likes the frictionless feel at this pivot point, so it's good to be able to adjust it to taste. Also when doing vehicle work or other situations where the arm may not be hanging level (probably more often the case with homebuilds!), this pivot might cause more trouble than it's worth. Note that it's not a necessity for the stability of the photography (unlike the other bearings in use around the gimbal and arm) but is useful for adjusting the position of the gimbal while operating to get a better view of the monitor, etc. It may provide a little bit of improvement in isolation but it would be hard to see the difference in the final photography.

Hello Charles:
Very clarifying!!!
Thank you.
I could see that the Steady Rig arm has a knob in the pin assembly to perform what you´re talking about.

Thanks.
