Engine update

I don't have a lot to report on the Hisso rebuild.  We are waiting for new rings to be made.  The ring manufacturing company gave us a February 2nd shipping date.  Plus, the OX-5 getting rebuilt in John's shop ran into some unforeseen problems and is taking longer to finish.  As soon as it's done, attention will be turned to the Hisso.

Anyway, John has been working on the sleeves for the valve guides.  He writes:

Here is a picture of the valve guide inserts. They are not done, yet. I have
a couple of the original cast iron valve guides bored and tapped to
accommodate the brass sleeves. None of the sleeves have be accurately bored
to their final ID as I plan to match them to individual valves.

Also, I am planning on machining about 0.060 off the top of each cast iron
valve guide so the new sleeves can be flared at the bottom of each cast iron
valve guide. The are threaded at the top and flared at the bottom

John also ordered the babbitt material for the main bearings.

More to come as things progress!

Matt Wilson sent me an email with these Jenny pictures.  His Grandfather was a member of the 120th Observation Squadron of the Colorado ANG back in the 1920's.  He had an interesting life!

Anyway, Matt's Grandfather went on to found Monarch Airlines which later became Frontier.  You can read a short bio here:

Thanks for sharing the Jenny photos, Matt.
