Thanks Wim and Tony. Btw Wim, is the Bull Frog suitable on the grand piano and who sells 'hide' string covers? Yes, I put the Rust Blocker under the string cover. In most grands, it actually holds up the cover, when I put the RB on a strut. The RB shield is about 1 foot by 1 foot square. -----Original Message----- From: limhseng <limhseng at gmail.com> To: pianotech <pianotech at ptg.org> Sent: Tue, Nov 23, 2010 2:03 pm Subject: Re: [pianotech] bull frog/hide covers Thanks Wim and Tony.

I do stand corrected though, there are many places where the humidity will remain relatively constant. From a Government source in Hawaii “Humidity may vary slightly on a daily basis, with an average of 63% humidity in Honolulu, and between varying climate zones and elevation.” One must assume that at some time the humidity does actually fall below 70%.. All areas have different terrains that effect the humidity content of the air regardless of what area you live in. Actually what I am saying WRONG to is the placement of the heating rods. If you put a heat source in an enclosed area like in the action cavity then you are drying out not only the action but also the tuning plank. In my opinion this is detrimental to any piano.

Tony With all due respect, that statement is wrong. In Hawaii, and I presume in other tropical areas, like Singapore, the humidity NEVER drops below 70%. Surpisingly, the humidity rarely goes over 90%, either. But it is always in that range.

Anywere that there is high humidity there are also periods of low humidity. Both rods have been installed in "hopefully closed areas" and when the humidity drops down to say 40% you can assume that these rods are going to reduce the effective humidity level down to about 25% causing the action to become loose and the soundboard to dry out to lower than it should be. Even fitting a humidistat to near the soundboard will not stop the action from cooking. One way only to do it properly, full climate control system with under cover under the soundboard, keep thr lid closed and close the key fall when not in use.

The heater on the soundboard according to the tech that installed it helps to prevent rust. The other rod in the action cavity is the standard installation in our hot and humid climate. Its on 24/7.
