A simple solution at a low price!

This calculation program is in fact an application in Microsoft Excel. To use it no other knowledge of computers is needed but a basic knowledge of Windows and Excel. As it does nothing more than can be done with pencil, paper, a calculator and a lot of time a humble price is asked for it: € 128,- excl. VAT.

At the start up of Bonamens VAT (19%) is not yet charged for. That may change.

For € 128,- you get three spreadsheets, suitable to calculate the strings of existing pianos depending on the data at hand.

The strength of this application is the simplicity of the operation, the clear presentation of data and results, but especially the possibility to join the new strings with the original strings.

Check these statements, download the manual and the example files and go trough them.

Fill in the order form when you are convinced of the usefulness for your work and transfer your payment to me. I will produce your copies of the spreadsheets -i.e. with your name and city on every page - after receipt of your order and I will send them to you immediately after having received your payment.
