Safety wiring

Call me strange but I actually enjoy safety wiring.....I find it relaxing
Drilling the holes is a lot easier with this sweet setup.

 I use some steel V blocks and a portable vise on my drill press. The blocks hold the bolts securely off the end of the vise without damaging the threads. I drill four holes (two cross holes can be drilled in regular bolt heads) in the allen head cap screws. Oil helps keep the 1/8" drills bits cool.

 The blocks will accept different diameter bolts.

The caliper bolt heads are tapered but can still be drilled.
