Figured out why my bubbles were always off-center

Honestly, tweaking the blowpipe speed did the trick.

My studio's old manual says 2.5 RPM for consistent gathers. Took me ages to realize my foot pedal was barely hitting 2. That slight speed up was a game changer for centering. What kind of glass are you working with?

Idk that "slight speed up" thing is true for most stuff

Not sure if it's worth all that fuss. Kevin110 talks about RPM like it's critical, but my bubbles turn out fine without overthinking it.
