Thanks for the re****t on that one... I was only looking at that this
morning thinking I could use it, but not knowing how well it was built
was an issue.
I see that you have set it up as a single row pano head. When I was
considering it, my plan was to remove the top slider and mount it
sideways on a bracket that bolts to the bottom slider. That way nodal
rotation could be done in two axis for multi-row panos.
Looking at the break down images here http://tinyurl.com/4blr5s
it
seems to be suited to making a multi row.
Cheers
Rusty
PS: I hope this post is not formatted to wacko and actually gets
through. I am trying something new to bypass the Google issue at the
mo.
