I know what it is but how does it work?
Picked up a Sjobergs Bench today & it came with a couple of add ons. Firstly there is a steel vice adapter plate which locks into the wooden vice, simple but effective. Secondly & here lies the problem, it came with a Sjobergs branded Holdfast which I hope the photos demonstrate appears to be a standalone item. I'm hoping this might work in conjunction with the bench (somehow!). The Holdfast itself will not fit the square slots already in the Bench & I can't figure out any way in which this separate unit works in conjunction with any part of the Bench as it is currently conformed. Any help much appreciated.
P.S. I can't find anything like this from Sjobergs on Google , even an image, very strange!
