hi John,
this eta car pic was taken last year.
The mount in this thread is actually my previous version and was just a prototype to understand how the weight distribution of a fork mount works.
I've made a lot of changes and completely rebuilt it from scratch. the current one is as you've seen with a push/pull tripod/pier and that's extremely stable and light.

this old one also only had a 20mm steel shaft which I changed to 50mm so more contact with the fork.
pic of the current one as at your place.
