Nev has an awesome blog about his build at https://www.bearhawkblog.com/blog . He also has a YouTube channel called Bearhawk Blog where he's updating us on his progress.
His builder log is at https://webuildplanes.com/neville and his expense list, which is very thorough, is at https://static.wixstatic.com/ugd/012017_b87ce91d3a9d4e2c9ec8675e5aebb295.pdf .

  Nov 29, 2020     Wing cradles - (4 hours) Category: Workshop

I make wing "cradles" that will attach to i-bolts hanging from the trusses in my workshop to store the wings up out of the way. I sandwiched two 2x6's together for each cradle and cut the contour of the bottom of the wing into the cradle. Then I drilled a 1" hole on each end of the cradles to tie to, and lined the tops with 1" high density foam to protect the bottom of the wing from getting scratches or creases.

  Nov 28, 2020     Rotisserie - (6 hours) Category: Workshop

I made a rotisserie using 4x4's for the frame. On one end I used a scrap irrigation center pivot gearbox to facilitate spinning and locking in place, and a the universal joint from a power takeoff on the other end.

Here's a link to a good builders log. John scratch build quite a bit, but otherwise is similar to my goal and has done a great job documenting his build.

  Jun 04, 2020     Cowl Flaps       Category: Research

Sufficient cooling of a 0-540 engine on a hot summer day while climbing to altitude, yet being able to descend rapidly on a cold winter day is somewhat of a challenge I'm concerned about. Research is leading me to believe cowl flaps could help me have the flexibility to do both.

Here is a thread on the Bearhawk forum with good discussion on the topic
http://bearhawkforums.com/forum/bearhawk-general-discussion-news/19571-cowl-flaps

I would like to avoid installing a lip. Tony Bingelis says "Some builders and manufacturers (also in desperation) resort to the installation of a large, deflected lip along the bottom opening in an effort to create a sort of venturi-like low pressure area to improve the airflow through the engine cowling. If you have to depend upon this double-ugly solution, you should probably restudy your cowling and cooling installation and rework it."

More modifications and scratch building than I hope to do, but has some great content.

  May 28, 2020     Bobby's Log       Category: Research

An excellent builders log by Bobby in Arizona. http://azbearhawk.com/ I hope to build very similarly as Bobby did. During my early stages of researching kit building a Bearhawk, I found the thoroughness yet clarity and simplicity of this builders log to be inspiring.
