Chain Leg Vise for Roubo style benches

My Roubo Bench was finished back in 2010 and It’s been a dream to use with one exception, the Parallel Guide and Pin on the leg vise were a pain to use. I never seemed to have the pin in the right hole of the Parallel Guide. BenchCrafted, who made the hardware for the Roubo Slit Top Bench announced a solution for that problem. It’s called a Crisscross and looked promising, except to install it required way more modification and changes to the bench than would make it at all practical…..
Enter Ancora Yacht Services – Chain Leg Vise (chainlegvise@gmail.com). It required drilling a 5/8” hole through the chop and leg, morticing a small ledge at the end of the parallel guide to hold a small angle bracket, then installing the two sprockets on the back of he leg, and install the chain. Total install time invested…two hours, and if I ever wanted to I can still use the parallel guide and pin! (that’s never going to happen)
This thing works like a champ, and the leg vise holds anything I can fit in it.
I made a maple cover that slides over the whole affair to make it dust proof and a little more esthetic, but that was totally unnecessary.
