You have to take your progress anyway you can. It's still 'frosty' here in Tucson also, I get up at 5, work till about 10 or 11 in the shop (or easy bake oven as some people call it) and then do my regular work about 8 or 10 hours. It's slow going but it's going.
Frustrating, I'd love to take a week off and hammer it out. It will be really interesting to see your project finished. Drive, crunch, trim. I think that describes a lot of aero mods.
Texas engineering, yehaa!
