Grand Piano Pinblock Replacement

For your piano to stay in tune, its stings have to be held with just the right amount of tension. That tension is held by the tuning pins. And if they aren’t up to the task, the piano will never stay in
tune.

The pinblock is to blame. On a grand piano, the pinblock is a piece of hardwood that sits beneath the cast iron sound plate. When it was manufactured, your piano’s tuning pins were fit snugly into pre-drilled holes.

Over the years, those holes become slightly larger. Temperature changes cause an expansion and contraction that wear away at the wood, and after enough time has passed the pinblock won’t hold the pins tight.

There are two solutions.

Pinblock repair

There are a couple of repairs that might give your pinblock a little more life. The first is to re-pin the pinblock with oversized pins. A larger pin will create a better fit, and this could hold until even more wear has occurred.

Another repair option is to use CA glue or another type of pinblock restorative. Treating the wood may also give the pins a better fit and longer life.

Either of these roads ultimately lead to the same place – replacing the pinblock.

Pinblock replacement

When enough deterioration has occurred, the best solution is replacing the old pinblock with a new, custom-fitted upgrade.

Pinblock replacement is an extensive repair that requires bringing the piano to our shop. In order to access the pinblock, we’ll remove the strings, tuning pins and the cast iron plate.

Once we have removed the pinblock, we’ll get to work duplicating it. This requires us to cut, fit and drill the pinblock just right to get a good fit. Once this is completed and the piano is put back together, your piano will be able to hold a tune again for years to come.

If you need pinblock replacement, call 405-749-3540 to schedule service from Bruce Piano.
