On this Kawai grand I noticed that drop was perilously close to the strings, barely a mm below letoff, sometimes double-striking on pp blows. 

So I pulled the action and found that none of my drop regulators would fit the drop screw! Is there a special tool I'm missing?

Thanks Wim - but I ordered that item, and its opening is the same size as the other two tools I already have.

There must be a unique Kawai tool for turning those fatter drop screws! Any ideas?

Perhaps Don Mannino knows, because he is very familiar with those shanks and flanges! Don, if you read this, please chime in with your sage advice.

Cordially,

Jason Kanter

I just ordered every drop screw tool Schaff has. They are all small and too small for the jack adjustment screws especially. You need the thin shaft on these to fit between the dowel let off buttons but with a slightly larger head. Yamahas usually need the jack adjusted and It's frustrating when you take 1/2 hour to do a 10 minute job because there isn't a tool made to fit those,,,, that I have found.

i talked to the people at Schaff explaining the problem and it wasn't like he didn't know about it. After spending 50 bucks on tools and now I have 4 that are similar,, I guess I have enough to trial and error with my Dremel. Strange, I have to do this. You would think a tool company would rise to the occasion. This has been a problem for the 20 years I have been working on pianos. When you only need to use it once every 6 months or so,,

You could try a flat let-off regulator, the kind you use for adjusting eye-screw let-off on an upright.  If I recall, I've used mine in a pinch for fat drop-screws.  It's way too wide, but the opening is probably about tight enough to turn your screws.

Try getting a set of ignition wrenches. The are flat wrenches made to turn small nuts. Advance Auto may carry them. Perhaps you can use a grinder or dremel tool to make something  from another tool or piece of metal or even a brass rod. a piece of metal tubing crimped around the drop screw may work. lets start a tool making contest

WNG makes regulation tools, I'm not sure if you can buy them individually but they have a tool for let off and a separate one for the jack. I will try to go by the dealer who has a Kawaii action model and check all my let off tools to see what fits. 

The WNG tools are made like an upright let off tool for eyelets and allow you to come in at a bit of an angle. Quite nice tools but the kit is pricey.
