yes sir, it will get the full rebuild job- barrel honed and all!

I would like to see this if you haven't already done it. Great pics and keep the rebuild demo going. Thanks

thank you drom for your interest,
my work can go from busy, to overwhelmed , faster than a Politician can take a bribe, unfortunately i did not take pictures of the honed barrel as anticipated.
because of proprietary reasons, i can't show the work performed, but i can show you what i used
an oiled, flexible cylinder hone, at low speeds to attain a fine cross hatch pattern.
not unlike how an engine cylinder may be honed.
the finish turns out very nice.

the pump is mostly reassembled, but i can snap some pictures of the progress.
i can make a video of the initial fire up, if there is interest.

I would be interested in the video. Completely understand about the work load, it can be busy one minute and the next… well, like you said overload.

I have several of those " dingle berry " hones for engine cyl finish honing and light clean up on blocks that don't require boring. They do a nice job. Mike
