The cylinder was off the valve block. I sent both to
Andy and he cleaned the cylinder and the valve-block
(loaded with glue of some sort). Then soldered together
the block and cylinder, tested the fix, and declared it
good to go.
I think the price was $55. I don't recall if that
included shipping.
I considered the work he did 'a blessing'. Soldering
those pieces together is beyond my abilities.
Give Andy a call.
