Refurbishing Parts:
Back in December, the team at Pioneer Aero began disassembling the SBD's tail fin to begin its restoration. While some parts were salvageable, corrosion had damaged others beyond their reuse. Thankfully the project also includes another fin from a donor airframe, and this provided additional original parts for the overall restoration. In recent weeks, Pioneer Aero's William Lowen has begun refurbishing some of the original parts, while also manufacturing replacements where necessary. This update reveals some of the progress he has made towards this endeavor.

Some of the ribs from our SBD’s fin required replacing. Here is a pair of new-build examples sitting on their forming blocks. Each of them still requires a lightening hole to be cut (and flanged) at the circular location indicated in ink. Following this process (and heat treating) they will be ready for primer paint and fitting. (image via Pioneer Aero Ltd.)

While the left two still require lightening holes to be cut and formed, the example on the right is ready for its coat of primer paint. (image via Pioneer Aero Ltd.)

Priming the Parts:
With the cleaning, inspection and repairs completed on the parts salvaged from BuNo.36175's fin and that of the donor aircraft, it was time to coat them with primer paint, as the following images reveal.
