Hydraulic DIY QCTP

If it was mine, I will just add a bleed bolt at the top of qctp

How about using bimba pneumatic cylinders.... A tire valve would do

Aha! There's the solution to the bleed issue, just put a Schraeder valve in the piston, hold it open
during insertion. There's plenty of length to play with, the piston can have a step to larger
diameter (so the tightening knob bears on the piston rim while the Schraeder stem is accessible
through a central hole in the knob).

I'm unsure, though, how I'd make a seat for a Schraeder stem. Maybe just solder in an
old brass stem from an innertube? What's the cost of a Schraeder reamer?

As for initial oil filling, I'd go with vacuum backfill; bubbles are a BAD THING.
