Good Afternoon people

I am busy with designing a scissor table, but I'm not sure I'm on the right track.
It's a double scissor table. In the first sheet, I calculated the reaction forces. In the second sheet, I calculated the forces in the joints. I have also almost completed the static calculation of construction.
I have only had the last joint and scissors to calculate. My Question I'm on the right track?

I have attached my calculation. Donít try to read the text because it is Dutch...

Thanking you in advance
