Bubble Level Attachment For T-handle Tap Wrench

[Toolmaker51]

Bubble levels! Ingenious, and convertible. It seems like I'm hand tapping in place frequently now; see levels and a block are going to the top of my list. Once weldments are assembled, they sure aren't going in any machine I can visualize. Breaking taps in machine frames is NOT how you win popularity contests.
Probably need a drill-bushing plate along with them...
