Hi, I'm hoping someone can help identify what type of screw this is
and what screwdriver I need for this, it doesn't seem to be a common thing in the Netherlands and my internet searches haven't been successful so far,
if more information is needed please let me know.
After doing some searching with the names you provided I found this "hack"
and it worked.
However I was hoping to replace the camera mounting plate from the macro slider in the first image with the one in the second image because the latter also allows for vertical camera position when used with an L-bracket. I bought the first one years ago and it's a solid build, the knobs rotate smooth with a nice resistance, the second one is less than half in price and is less smooth. I have a work around for the first slider but it's a bit of a pita.
Long story short, I was able to remove the screws from the second slider but the ones on the first are sealed with an adhesive and I broke off one of the screw heads so that's not going to work unfortunately.
I'm going to leave it as it is, it won't fall apart so it's just aesthetics. Obviously I was hoping to combine the best from both sliders but I'm going to use both and see what annoys me less, the work around or the less smooth mechanics
