Anti-Twist Plate for Toyo 810MII

[Sal Santamaura]

...Will the extra bite will prevent the screw from working itself loose?...

I don't know, but some Loctite Blue 242 might.

Thanks Sal. If it doesn't, I may try that.

This may not be of any help, but I use these and love them- it's the same plate that's used on several Manfrotto heads, including the 410 geared head. It's available with the plate and base mount which you can attach to any tripod head: https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
I use this plate on my Chamonix 4x5 and Mamiya RZ67 Pro, with zero twisting whatsoever.

That's the one I use on my Toyo 810MI (in combination with a FOBO Asima (sp?) tripod..no problems whatsoever..

UPDATE

I exchanged the Arca screw with one that has one more turn of bite and it seems to have worked: I haven't had to re-tighten the screw since.

Spring 2019 UPDATE

After a year of using the MII with the longer screw there has been zero "nodding." So the extra 1 turn of bite was the solution.

Also, I have the plate mentioned in post #23 and use it on a Manfrotto 475B with the big binoculars in conjunction with a parallelogram mount and with the Toyo Robos with a Bogen 329 RC4 3-way head. I don't backpack with the Robos so I'm unconcerned with the extra weight or folded length.
