Sorry for all the dumb posts-new to acoustic pianos!

This is the correct screw for the cheek blocks?

Very tight, turned a bit though.

Ideas? Counter-clockwise turning by the way.

Perhaps I’m weak... my tech said my piano seemed like a furniture piano previously, maybe never unscrewed since 2008?

Saw YouTube videos, seems like they easily unscrew.

Thanks for replying and reading my posts 😄

Yes it is. You could use a wrench, or some sort of bar between the wings to give more leverage.

I have to turn my wing nuts to the right (clockwise) to loosen. You might need to wiggle the cheeks with one hand as you are loosening. I place some fingers on the front side and the key side of the cheek and wiggle. Needle nose pliers will work well and give you additional leverage on the wing nut.

Those are big wing-nuts for a cheek block. Clockwise to undo is correct. Don't forget to lubricate the threads before you re-assemble to avoid having the same problem next time you want to take them off.

I also have a Kawai and mine are a right hand thread, so they turn counter clockwise to remove. You can buy a wing nut driver it it's really stubborn. That's a really large wing nut, you can probably use a large screwdriver as a lever between the two wings to remove it. I'd wrap the screwdriver with electrical tape so you don't scratch up the wing nut.

Why would those screws be non-standard and turn clockwise to unscrew?

Which angle are you using., you looking through the keys?

@BDB
Yes I need TORQUE!

@nrighton
Good strategy, will try later

@Jean Claude
Was thinking that, I’ll look around my garage for lube!

@MarkL
I’ll definitely apply the screwdriver/plier trick if it’s too stubborn! Do not scratch my new piano!!!

@Learux
Yes I was wondering that, MarkL counter clockwise loosening but others do not?
I didn’t really try hard yesterday, just seeing. I’ll look through the key.

Thanks 😊

The only proper lube to use on the screw threads is beeswax.

PLEASE don't use grease!

There is no need to lubricate. Just do not tighten them so tight. Weather can make it tighter. Soap can work as a lubricant.

Was just going to look around my garage, I needed some for something else anyways.
I know piano is so delicate.

Maybe humidity made it super tight?

It was likely humidity. That, and moving the piano may have knocked things a little out of whack.

Success! Clockwise to unscrew I guess.

Used a adjustable wrench and clamped down on one of the wings!

Whether it is clockwise or counterclockwise depends on whether you are looking up at it or down!
