Step 5Prepare the V Block
First, we'll prepare the holes that will allow us to clamp the V-block to the main beam.
On the underside of the V-block you'll find a centerline built into the extrusion. Scribe a parallel line 3/4 inches on each side of the centerline. These two lines should match up to the T-slots on the extrusion. Then scribe two lines perpendicular to the centerline, one at 1 3/4 inches and the other at 3 1/4 inches from the short edge. At the intersection you've marked, centerpunch, drill, and tap to M8.
Now we'll add the holes to mount the clamp and spacer.
Scribe a line 0.4 (13/32) inches in from the long edge, parallel to the centerline, and then scribe two lines perpendicular at 2 and 3 inches from short edge. At these two intersections, drill through 5mm or 3/16", then countersink deep enough to fit your pan-head M5 screws to be slightly below flush.
