More math. Solving for other angles. This unit draws on your trig skills. Most of the time we work with only a few fixed angles depending on the fittings we use-- 22-1/2, 45, 60 and 90 degree elbows. Occasionally, we need to be able to use trig to solve for other angles.

Sadly our T- Drill is broken but this is how it should work.


And this is the sort of thing you might make.
