You could also use the V-blocks together with the vise. Use the V-blocks to set the orientation and height in the vise, though you'd likely have to but spacer blocks under them to bring the workpiece up to the proper height in the vise. Start with both V-Blocks on one side of the vise, supporting the long end of the workpiece. Clamp the work into the V-blocks, not fastened to the table. Then clamp the vise to hold the work. Make your first cut.
Now remove the spacer from under the V-block that's closest to the vise, and move that V-block & spacer to the other side of the vise. Loosen the vise, slide the work over to the other V-block, clamp the vise and make another cut. Lather, rinse, repeat.
Easier to do it than to describe it.
