As some of you will have noticed the camera mounting plate of the CS6 is a bit flexible to support the 3 Axis Gimbal. I found a little trick that consists in matching 2 "Camera Mounting Plate" with 5/6mm spacers. With this assembly, the 2 mouting plate are very rigid and does not bend at all because the weight of the frame. It is only the O'Ring that works and the result is much stable with video, more, the little problem of the screw touching the pulley has completely disappeared ...!
Machining aluminum 5mm The middle scooped out the parts you do not need to 2mm, and is used to reduce weight.
E-One, that looks like a neat solution to stiffen the gimbal mounting plate, I'm considering doing the same with my CS8, can you share some comments whether this has improved vibration issues for you ? Any other observations ? Thx, //Berndt
Hi Berndt, on the results of this assembly, I would say that for a 5D/7D gain stability is strong enough as it is really only the "O-Ring" wich work. But with a lighter camera, the results are the means of spacers that touch mostly the edges of dampners and this give to the gimbal few vibrations. Finally, for a camera of 1.8 to 2kg it is perfect, but for less than 1.5 Kg it is not suitable because the gimbal is really too hard ...! But for sure if you want a stiffer gimbal, you can give a try this method.... Marc.
We are mostly flying D800 with 20, 35, or 50mm primes so we are in the 1,5kg range. Maybe I'm chasing ghosts here but my feeling when observing just plain hovering and gentle movements in calm conditions is a twitch/shake kind of movement, and it's not the vibration isolators bottoming out or Radian introduced (no real difference noted with slew mode on/off). I'm going to give your modification a try if nothing else to be able to eliminate one possible source..... -Berndt
Berndt, I'm having the same issue. Did you do this modification since this post? If so, did it help? Phil
We had the same issue with the CS8 mount for 360 too. So we bought another mounting plate, just got longer screws to mount it (no spacers) and it's so much better. No flex. It's a pricey solution. Perhaps they'll beef up the newer plates in the future and make them twice as thick.
Brandon, Did you glue the plates together? Or just screws with nuts with nut lock? Could you post a picture? Phil
Phil I'll get a picture for you later but it's nothing special. No glue or tape, just the screws holding the plate to the CS is what keeps the thing ridged. You'll need longer screws for mounting though.
Double mounting plate for the CS8 to 360 gimbal. No glue. Screws are longer here and to mount to the CS.
Brandon, Is that freshly poured brew in the background? I'm guessing this is part of the modification correct? Phil
Just got them at the local hobby shop. I believe I got 3mm x 20mm. If you're using the 3 axis gimbal, take the existing longer screws from the pulley and use those where the shorter screws went and replace those with the longer screws. I think I just confused myself.
