Drilling a Hole In the Center of a Rod without a Lathe

[rgsparber]

Drilling a hole in the end of a rod is easy... if you own a lathe. Here is a trick for doing the task using a drill press. Don't own a drill press? All is not lost if you own a bench block or a block of metal drilled to the rod's diameter on a borrowed drill press.

Way cool! Excellent way to center drill.

It's quick and accurate 'enough' for everything I do.

Thanks!

Another use: make such a jig same major diameter as the stud you just broke off. Drill the smaller hole, flip the jig and set it on the broken stud. Now you can use the smaller drill to get a starting hole exactly centered on the broken stud so you can drill it out without barfing up the threads in whatever the stud is in.
