Review on Enhanced Precision with Big Horn 14510 Blank Centering: Perfectly Aligned Results by Pressure Cook

The big problem with this vise is that only one side transmits the force through the screw. This causes the other side to bind when tightened and the inserts on the unthreaded side to warp more. As long as the stock has corners for the V-shaped center plates to grab onto, you're good to go. However, it will not work as well with a round shaft. Also, since the V-notches on the plates are made smooth, the shaft doesn't hold as securely as one would like. The vertical pressure of the drill lowers or pulls the shank up. Tightening the vise seems to be the solution, but see problem #1 above (skew results in not very secure stock grip). I usually attach the vise to the drill press table with short Jorgensen quick-release skewers. This allows you to quickly change the position when installing other material or changing the position of the table. In general, the vise is suitable for centering short (3" to 7") rectangular materials up to about 2" per meter on a side.
