Another note about the baileigh notcher vs the ol joint jigger styles.
On my OG original OL joint jigger I would destroy a hole saw in about 10 copes. With the baleigh, I've used 2 hole saws on 3 cages and one exo... One 1.75 that is almost done, and one 2.0 that's still new.
The one cage had almost 50 copes and the others had less.
Definitely makes the hole saws last longer when used with a good notcher. Running it with a hitachi 1/2 drill nothing special.
