I like your ‘sharp edged preparation’, Uwe.Some more info about the preparation works on the riders
Here a close up photo - the elements for the riders are not laser cut, they are cnc-milled, so no laser char removal necessary but we have to clean the areas where the parts are fixed to the sheets.
On the left side a rider in original shape directly out of the sheet - on the right side with sanded and cleaned surface

Also, when you build the same model, I suggest now to clean also the notches for the beams, and not to wait until the riders are finally installed inside the hull.
Now is the time where you have a much better access for the knife and file
On the bottom marked with red arrows are the rounded edges inside the notches visible - they can not be avoided during the cnc milling
On the top you can see similar edges, marked with green arrows, cleaned and prepared with a sharp scalpel knife

These rectangle edges in the notches are necessary, that the square beams for the mortar bed will fitt - see the following photo (all dry fitted)

Many Thanks for your interest in my work and building log of the CAF kit of the HMS Granado
