The traditional if alarming way is two sheets of heavy glass to make
a sandwich, and apply heat gently. A hot sunny day will do it (mask
label against fading--I forgot!), or a low oven.

There used to be a hi-fi fanatics' record player with a platter
which was a mini suction table - you pumped and played. If you can
track one down, you can then  make recordings from the lp. I'll
email again when I remember who made it.

On a similar principle, at home I place record on the turn table,
then use a small rubber grommet pushed over the player's spindle to
hold the centre down, and so making the lp flat - enough for minor
warps.
