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.

Top posting. One solvent that does not bother solenoids, and is an
excellent cleaner is transmission fluid. It does not bother rubber tubing
either, and is not very expensive. I do remember tape punches, and wish
you pleasure with yours.

One irradiated spray bottle full of it, from your local hardware store and
auto parts store should suffice.

Shell X55 used to be the stuff - dont know if its still available, used
to put entire teletype machines in a spray booth, hose them down with
it....

I'd suggest PB Blaster. It's a good penetrating oil, it will get in
between everything and at least have some solvent action. Hit it with
the PB blaster, cover it, leave it for a couple days, then start trying
to flush gunk out with naptha.

Consider using something like a high-grade turbine oil so that it doesn't
gum up so easily next time. The Zoom-Spout oil from Ace Hardware is fine,
and about equivalent to Castrol OC-11. Another good choice is the Royal
Purple Synfilm 32, which is a much stronger solvent than typical petroleum
oils of the same viscosity and is my first pick on old gear that may have
residual glop left in there.

NOT PB BLASTER !!!!

I love that stuff for breaking up rust .

But right on the can is a description of how well it melts a styrofoam cup.

It will melt rubber and plastic.

Yes, it WILL melt rubber and plastic, very strongly. Be careful with it.
It's okay on some phenolic plastics, but styrenes and vinyls are very
quickly destroyed. And it may not even be okay on all phenolics so test
first.

This is not a reason not to use it, it's just a reason to be VERY CAREFUL
when you use it.
