Irving,

Good to hear from you, hope you are well.

Thanks again for the information and pictures. The heat sinks are quite big I see.
As I am experimenting I don't mind using a lot of aluminium at this stage. (junkbox full !)

I took notice of the fact that current limiting should happen on a per winding basis.
On My circuit board I have allowed for the 2 current limiting resistors for the L298.
It's not clear in your picture whether your boards have them fitted or not.
Will the L298 perform the necessary current limiting with those resistors or should there be an extra current limiting circuit.?
