I actually use a ryobi scroll saw like this one.

It gets me close then I use files to fine tune it. Then I start with 400 grit and go all the way to 2000 and then it's Mothers time. All by hand. Not a lot of fun but it kept us going till I found a job. The Impala emblems were a real big seller for me. I sold over a 100 of just the large 36". I did a few 12" but most were the small ones (I think 8"). I still have the patterns. Then I branched out to casting 1/8th scale model parts. That was (and still is) very lucrative. I'm a pretty diverse guy.
