I have a York vise (the biggest) and I’m quite happy with it.
I can and do recommend to keep the threads clean from (saw)dust before closing the vise !
If you don’t the half nut that engages the the threads will clog up quite fast..
Oh and do mark the bars relative position to the moving jaw, in case you have to take it apart.
Don’t ask me how I know that one…
Got mine from fine-tools btw
