I’d meantioned this in a different forum, now with my own camera I can follow through.
An idea borrowed from the Veritas, Tucker vice.
It works with the Record quick release vice, or clone as I have, and should be adaptable to ther styles as well..
The release is linked to the small bloc you can see the eye bolt in. I crawled under the bench, faceshield
firmly in place, drilled a hole and tapped it for the bolt. Then added the chain and ran it to the hinged step below.
That way the release is hands free
