No words to describe the workmanship, fit and finish. Awesome seems inadequate. You made the side-shift cylinder? Would you be willing to share you construction methods, especially what seals/o-rings and how they are arranged on the piston and head.

Thanks!

All seals are o-rings. Both piston and rod are sealed with two o-rings. The cylinder tube has threads in both ends, and the end caps are sealed with 3M Hydraulic Sealant HP42.
The most hardest task is to make the o-ring grooves to the cap that seals the piston rod.
My side shift cylinder has 4 mm piston rod, so you need very small tool to cut the o-ring grooves with lathe.
And of course the grooves MUST be in correct size, or they won´t hold the pressure
The picture you see here is not the side shift cylinder, it´s one I made earlier, but it´s made the same way so you get the picture.
