No one is able to help please.

From Fotoshop the largest coil is 32.5mm long in the first image, the text in the third image says it should be 13mm which is 2.5 times smaller. Dividing the overall size of the layout image gives 90x45mm near as damn it. The dimensions are not critical so long as the clearance for the capacitors is correct.

will see yellowbeard thanks i guess anyone having an lpf to homebrew for less than 100 watts .

You can improve the filter performance by putting earthed screens between the coils. The screens need to be at least the diameter of the coils away from those coils, to prevent loading the coils and lowering their "Q".
