MDF forms a surface skin when pressed. To machine 25mm to 19mm would seriously reduce it strength. You would better to use 18mm with a 1 mm spacer where needed or to convert your plans to metric. If you can get me full solidworks plans I will convert them to metric for you.

The metric conversion of 3/4" to mm is 19.05. So we could machine a 25mm board down to 19.05mm, or as you suggest - change the dimensions to suit the 18mm board. Not sure which way to go yet.
Found another good thread which has a file for nested base cutting of the MDF board -

Look at post no.2 from Joe.
For interested members, we will post more on this subject as progress is made.
