Just go to Goggle images and search for "cracked piano bridges".

Here is one I ran into today when going to do a tuning for a new client. This is from a 1950's Acrosonic at the very bottom (left) of the tenor/treble bridge. I took the pic with my cell phone so I could send it to the client who was at work, so the quality isn't the best.

Great picture of the cracked bridge - it sure looks scary to anyone who views it. However, this is not a typical example of damage due to humidity (or lack thereof). In fact, damage to bridges is not listed as one of the negative effects of uncontrolled humidity in the Dampp-Chaser promotional video on the same page.

I have seen my share of bridges that have cracked this way, but the culprit was not the environmental conditions. It has more to do with quality of design, materials and construction. A DC would not have saved that bridge.

Jurgen,

You might be correct. But, i do not recall having ever seen a split bridge like this (or a cracked apron) in a piano that had a full D-C system installed from new. I have seen plenty of split bridges in pianos without a D-C system.

Of course, YMMV.

I think it has to do with preventing the piano from going excessively sharp with humidity more than preserving the wood.

If you notice the split in the pic I posted, the bridge failed in the very low tenor... which would be where you would find very wild swings in pitch from winter to summer.

Edit: If there is poor workmanship and materials, a D-C system will reduce the extremes to which the weakened system is exposed, which certainly should be of benefit.

Joe,I was referring to Scott's cracked bridge picture.

Your picture is one more good example of poor design and execution, leading to a weak spot where failure will then occur. Again, a DC would not have prevented that.

The Pic posted is just fine and does the job.. Loose pins are hard to photograph.

Piano stability or lack of it is hard to photograph.

Many of my clients still don't read the text on my site.. One lady said she liked my site, as I sat down to start tuning.. and then brought out her vacuum cleaner.

Interesting, I've seen bridges with the grain in the wood going horizontally and vertically. They still crack. What is the best design. What wood type is best? Sometimes, the cap of the bridge cracks.. sometimes I've seen the cap and the base crack? Maybe graphite would be a better choice? Anyone try that? It would be interesting.

I've got a Mason & Hamlen in a Church nearby that had small "eyelash" type cracks coming from a few bridge pins.. after the Dc was installed, those cracks are not visible... even with a strong light!

Then again, My Yam spinet I bought in the early '70's still has stability problems and some loose pins and that's even after I installed a DC over 5 years ago. ?? Oh.. no bridge cracks.

Different pianos.. different situations... different designs... different conditions... Challenging to say the least.

Scotty
