Neil, Yes 3003 and I anneal before butchering.
Mike: Well I started on the buck Monday morning and got some of the pieces made then pretty much the next 3 days. Got it pretty much done Thursday morning and then finished some internal flow guiding parts this morning and mounted to the body. My guess is at least 30 hours sheet metal to finish, lots of small detail like trying to get the air to flow somewhat toward the engine inlets and making the mounting hardware, etc. and it still needs at least 4 or 5 more to get it smooth enough to paint but it will do for this year! Got some good training on my little English wheel too. Not "Don Borth quality" but I think he would approve.
