View Full Version : Mounting 8x10 Tripod Blocks

I recently bought a Toyo 810G that came with 2 tripod mounting blocks. What accessory would I need to mount both blocks to the same tripod with the following heads:
1. Manfrotto 329RC4.
2. Arca Swiss z1-sp
Each 8x10 block measures 2.75" or 70mm in length. Attaching the camera using 2 mounting blocks instead of one would greatly improve stability.
I'm thinking that these may work:

2. http://www.bhphotovideo.com/c/product/329098-REG/Acratech_2132_6_Quick_Release_Plate.html

The Acratech seems to be a quick release plate for use with their heads.
The Manfroto mounts with a 3/8" screw and seems more universal.

For more overkill & weight.... Bogen 121DD, and more $ too.
Looks cool though.
Happy 8x10ing!

Not necessarily, I am thinking. If the lower connection on the head goes down to one bolt, how many connections above that may be less important. But I am no engineer.

Oops, I meant to type bogen 131DD.

I wonder that too?
My hunch is that using two blocks is best with two sturdy tripods.
Second best (but more practical) would be using two blocks directly on head with a long top plate, like the Gitzo low-profile 3-way 1570 that has a big plate with two mounting screws.
Third best would be the plate set-up if the plate long enough that the tripod blocks are spread out and the plate is very rigid and the whole set-up doesn't have harmonic vibration....
I think the Sinar plate is 18" and I bet the Swiss did it that long for a reason. But it also sells for $200 used so it probably is a pretty beefy piece of Aluminum.
But of course, you probably have to test this in the field. I quit Engineering school to do art.

Here is a photo of the camera from the e-bay auction:

and it does look like the Gitzo 1570 head is being used in the picture. I'm wondering if I can duplicate that with the heads that I already have. Although the camera is being held by one bolt, two mounting blocks attached to the rail should provide for greater stability.

Actually the camera is being held on by two bolts, one for each block. The reason I mention that head is because it has the slots and room for two of the Gitzo camera bolts/screws (whatever you call them). It think it even sold with two included.
Some of the old wooden 8x10s used two mounting holes as well.
