also your sealing face looks almost as if it would slide into that silver busing in there.
No it doesn't, it sits on that..it's just not to scale
The seal looks a little off center, witch can allow the piston to slip in a little to the side thus loosing the sealing area. That's my guess. If the center bolt where big enough around to keep the seal centered it might seal...
Nope, it's on center, and it's tightly on there
Any distortion of the rubber may wrinkle the surface preventing an initial seal. I found wetting the rubber with a water based marker (coloring marker) and quickly assembling it will show spots that are not touching. Proper use of a valve lapping compound can often fix some surface flaws. Low speed on an electric drill and time can wear the surfaces together in a perfect seal. I hand lapped the valves on my Mouse Musket and Dragon cannons to get them to seal.
Ok, I'll give that a try.
How close does the piece holding the rubber seal on fit inside of that sealing face? Can't really tell what it is (by the way, your camera was working fine, it just focused on the top of the bolt. )
The rubber sits on the sealing face, not inside it.
maybe the air is going between the bolt and rubber
how did you attach the nut to the barss fitting mabe going that way
It's pretty tight, and it is attached by a ground-down nut.
Just a quick note on Macro photography with autofocus digital cameras, use the half press to hold the focus (locks) and then re-adjust the distance to focus on the portion you want sharp and finish taking the picture.
Yeah...I did that, but it was still giving me crappy results. oh well.
