ahy/aɪ/
Start with your jaw open wide and your tongue resting low and flat. Glide the front of your tongue up toward the roof of your mouth as your jaw closes halfway.
m/m/
Press your lips together. Air flows through your nose. Vocal cords vibrate.
l/l/
Place the tip of your tongue against the alveolar ridge just behind your top front teeth, the same contact point as /t/, /d/, and /n/. The difference is what happens to the air: for /l/, you let it flow continuously around the <em>sides</em> of the tongue (that's why /l/ is called a lateral). Turn your voice on the whole time. Lips stay relaxed, no rounding or flaring. For the Dark L variant at the end of a syllable, also pull the back of the tongue up and back toward the soft palate.

Questions
Questions people ask about this.
How is "timeline" stressed in American English?
Stress falls on the first syllable — say "TAHYM" with a longer, fuller vowel and keep every other syllable short and quick. The respell "TAHYM-lahyn" marks the stressed syllable in capitals so the rhythm is easy to read at a glance.
Is the American pronunciation of "timeline" different from British English?
American English uses different vowel shapes, a relaxed retroflex R, and connected-speech tricks like flap-T and glottal-stop T that British Received Pronunciation generally avoids. The respell "TAHYM-lahyn" reflects the casual American form; British dictionaries typically print a citation form with crisper consonants and different vowel choices.
