I hauled in all the steel parts to Johnson Sandblasting yesterday around 5:00 in the evening... About 11:00 this morning, my phone rang; the parts were already sandblasted and ready for pickup! Talk about fast service!
I ended up picking up some primer and paint at Menards and got to work this afternoon. Here's my progress so far. I'm hoping to have the siren completely primed, painted, clear-coated, and decals applied by the end of this week, as well as having it assembled on the test stand. I'm still waiting on new drivers and some parts to repair the rear cover, but hopefully I'll get that all taken care of and assembled onto the rest of the siren by the end of March.
The cabinets still need a few components ordered before they're ready to go. I will of course get them primed and painted sometime soon, likely in March, and have the whole thing ready for a test run by April.
