Tom and Dave live in Simi Valley and are working on this project at KWHP ( Whiteman Airport in Pacoima, CA). Tom is Dave’s brother-in-law and taught him auto mechanics.  Tom and Dave are both retired. Tom is most skilled at the mechanics, and owns a very classy classic: 1957 Ford Thunderbird that he restored.  Dave’s strength in this endeavor is electronics and is a pilot. We completed most of an RV9A so now we both have significant sheet metal skills.
