I have acquired what to me is an unusual design for a small vice (I'm from UK),
-Don't know what the proper spelling for this object is in the UK but across the pond your spelling would suggest that you've acquired a new hobby or activity (vi
ce) as opposed to a clamping device (vi
se). I'm old and from Appalachia.
What I don't understand is why do both jaw faces have fixing points?
-I'll take a guess. The two sets of holes allow for mounting options. Perhaps someone would prefer to mount the vise so that the moveable jaws extend/retract
over the bench instead of
away from the bench. Imagine you have an already crowded shop and there's just a narrow aisle to approach the vise. Would you want to wind the vise to open/close into the narrow aisle you're standing in or would you want the moving jaws to extend away from the already crowded place you're standing in?
Any suggestions as to what this is and what it was for?
-If it's a v-i-
s-e you're asking about then it's for whatever you need it to do. If it's a v-i-
c-e then it's for whatever you fancy. We don't activity shame consenting adults here.
There are two vertical v slots on one jaw and one horizontal v slots on the other jaw.
-The two vertical and one horizontal "V" slots are to hold small round objects with less damage than just flat jaws would. Flat surfaces (jaws) tend to leave "flats" on round objects due to the increased clamping pressure on just 2 contact points. A "V" needs less pressure to secure, has 3 contact points, and offers a convenient locational alignment (horizontal/vertical) for common tasks.
-Hope I've understood your questions and that this helped. As it's your first posting here I welcome you to the board.
