Working with the aperture system in Canon FL 50mm 1:1.8

There was nothing wrong with the aperture system in this Canon FL 50mm 1:1.8, I just show you can disassemble it and assemble it again. To lock the screws I use the most soft thread locker, Loctite 222 it's purple color. You can also use the blue, with the number Loctite 243 but it's not so soft. If there is some oil in the aperture system and on the aperture blades, you can clean the aperture system and all the blades with 99% Isopropylalcohol Here are some link's to different repair tool's and lubricating stuff: "ORBIT" HEPA Blower: https://photosol.com/products/orbit-h...
