PLEASE READ THIS TEXT BEFORE ENTERING THE DRUM SIZES:
The following two tables are used to input the shell sizes.
The numbers on the left (y-axis) represent the DIAMETER.
The numbers on the top (x-axis) represent the height of the drum.
For technical reasons you can only input one point per row.
Also once you clicked in one row, you can not totally remove this data from the row again. So please choose carefully before you click so the sizes will be transmitted to us in the right way.
Sorry for this technical flaw!
