I have two mostly complete BRPE tape punches. You know, the old ones
rated to go somewhare arounf 100 CPS.

Problem is they've been sitting for a few decades and all the
mechanical parts are all stuck with Aunt Jemima's tty Oil and Pancake
Syrup it seems. There's no way the little levers are going to flick at
100 cps! Can barely flick them by finger in about a second.

I've tried squirting various solvents into the rats nest-o-levers.
Helped a lot but several are still very sluggish.

I'd dip it all in TCE but I don't think the solenoids would like that.

Unles anybody has some ideas, I'm going to rig a little aquarium pump
to trickle solvent through the maze-o-levers for a week or so or until
the levers loosen up. Then again, the solvent might dissolve the pump
and tubing so I end up with plastic glop all over the critical parts.

Any ideas appreciated.
