Before buying this vise I read numerous reviews of rotating head vises meeting the following criteria:
1 Jaw Width: 5"
2 Jaw Opening: 5"
3 Rotating Base
4 Independent Rotating Head Lock
5 Weight 40-50 Lbs.
Note that some rotating head vises do not have independent head locks, these were not considered here because head rotation is only locked by jaw closure. These are clumsy to use in some situations where clamping of the work-piece first is preferred so that it may be easily positioned and repositioned while clamped in the vise jaws.
Vises Considered Include:
Grizzly T27893, 45 Lbs. (The One I purchased, Beefy and Well Made)
Wilton 69999, 45 Lbs. (Looks like the Same Vise, but Costs More elsewhere and is reported not to be as well made.)
Yost 750-E, 42 Lbs. (Comparatively Lean Construction, Street Price $135)
Capri Tools CP10218, 21, Lbs. (Made from Ductile Iron, but Wimpy, and Cost Over Twice as Much)
Capri Tools CP 10519, 40.5, Lbs. (Made form Ductile Iron, Probably has clamping power equivalent to some of the others, but Cost Over Twice as Much)
Yost 750 DI, 63 Lbs. (Made from Ductile Iron, and as the weight suggest, this vise has increased clamping power, but Costs Over Twice as Much)
