Tips and Tricks

"Removing Strikers"

If the striker bellows are at all stiff, they should be replaced. There is no "easy way" to remove them from the tier, but there are techniques for reducing the damage. The one I use most often, when the deck boards are either thin or reluctant to break off cleanly, involves heat. Basically, I cut open the bellows, fold the moveable boards back and out of the way, and then super heat the deck boards with a clothes iron (set on Hi) for a few minutes. This softens the original hide glue to the point where the bellow will come off easily. To avoid warping or accidentally cracking the board in half when I take it off the tier, I use a heavy straight edge (like a chisel) and force the board off sideways. (see diagrams below the video).

The other more common technique is to chisel the bellows off of the tier. There are basically two tricks to getting the deck boards off with the minimum of damage. First, using a strong, sharp knife or a thin, sharp chisel, cut away the hide glue around the perimeter of the deck board. This is quite a bit more important than it might otherwise seem. The reason for removing the glue before attempting to chisel off the bellow is that it creates a very strong bond between the cloth and the tier. Breaking the bold greatly reduces the amount of force needed to remove the deck board from the tier. A second benefit to removing the glue first is that you are, in effect, scribing a very clear line which shows exactly where the bellow is located. This makes putting them back 'on' quite a bit easier. The second trick is to carefully watch how the deck boards are 'splitting' away from the tier. If they appear to be cracking in the same direction as the chisel angle, attack the bellow from the opposite end. If it seems to be cracking in the same direction again, attack the available side of the bellow. By attacking the bellow a little at a time from all possible directions, the amount of breakage will be reduced.

Lastly, I have a basic "Rule of Thumb" when it comes to removing the deck boards. If I break three boards in a row, or if the total number of broken boards reaches six, I use the iron. Mind you, using the iron might not be practical in every case. If the valves and/or the pouches are in close proximity to the deck boards, they will get ruined by the heat. The same is true for any leather gaskets that are close by. So choose your method wisely!!

=============================MORE INFORMATION=========================

Here's an email that arrived on January 26, 2004, and my response. It deals with removing the stationary striker boards when they have been previously glued down with a carpenter's type glue.

John , 

I'll try to be brief.

I've been in the player piano field since 1980, filling my own local niche.
(Enough back ground) I now have a player in the shop that has the pneumatics 
reglued on the decks with what looks to be titebond or similar,about 20 years 
ago.I've been spared having to deal with this situation till now(i can't believe 
it) But I have had to deal with Elmers glued air motor boards, bellows cloth,
and the Perfex, PVC to wood mess. I have never seen anything written to actually 
deal with this problem, only that many have dealt and do.. and not to use the 
wrong glue pep talks for the novice...yada, yada, yada.

My only experience with yellow glue near this area ,is reconstructing poorly 
glued heavy joints that have fail from poor fitting.,,but not on player actions 
(so far)or delicate parts. I expect to make new stationary boards. It's 
preventing too much deck damage and salvage I'm concerned with.

Hope you can direct me to some helpful info..or a least moral support.

Hi David, There are really only two choices. One is quick and requires good tools and a high degree of accuracy. The other is hot and messy, and requires a lot of patience. The quick way is to saw off the stationary boards with a table saw or a good band saw. The only trick is getting everything set up correctly so you don't remove any of the wood from the tier. The second method is to use a steam iron and super-heat the stationary boards until they come off easily. Once the moveable boards and hinges have been removed, you can usually heat 3-4 boards at a time. I set the iron to the highest setting and leave it sitting on the boards for about 3-4 minutes - until the wood discolors or starts to smoke..... ;-) Then, using channel-lock pliers or a heavy metal straight edge, I move the boards sideways (not "up" like you might be inclined to think). This prevents any of the wood on the tier from accidentally pulling away - if the glue hasn't softened enough. If the pieces are reluctant to come off, apply heat for a couple more minutes. If they are still reluctant to come off, get a terry cloth towel, saturate it with water, lay it over the boards, apply the iron, and create "major steam". (This can be very dangerous because the steam will 'burst out' from around the edges of the iron and rise very quickly. It's best to wear heavy gloves to prevent the possibility of getting burned.) You might wonder why I shy away from using steam in the first place. It's because that much steam, used over the entire length of the tier, will have a tendency to warp the tier. Sorry I couldn't be more brief......... Lastly, considering your experience, would you consider a free player technicians listing at Player-Care? If so, just fill in the form at: Musically, John A.
