After spending the last week or so on the CAD program and cranking out some parts for friends on the lathe and the mill, I'm finally back on CRLS. I needed to clean up the inside of the doors so the acoustic sheet would adhere to the surface. After I got the doors back from the blaster, there was still a lot of the original factory asphalt based material on the inner surface of the skin. Blast media won't really touch that stuff, so out came the scraper. Some of the gunk chipped off readily, but most was stuck pretty tight. I quickly tired of using a putty knife and hammer, so while my better half was out running errands, I asked her to stop by HF and pick up a pneumatic scraper. Turned out to be the best 20 bucks I've ever dropped there. I generally have low expectations for their tools, but this one is a solid piece. Took me longer to scrounge up an air fitting and install it than it did to remove the rest of the door crud.

After scraping and wiping down the surface, I cut the Rattle Trap to length and started laying it in. It conforms pretty well with the shop at 70 degrees and it didn't take long to cover the entire inner door surface. I always cover the seams with aluminum Shurtape because when the acoustic material gets warm, it will "bleed" droplets of the black asphaltic material. Covering it with aluminum tape seals the seams and edges and locks in the pookey.

I mocked up the door bottom again and drilled a hole thru the door jamb and one in the speaker box for routing the speaker wires when the time comes. I cut a length of 1/2" thin wall chromoly tubing to run between the jamb and the speaker box. I'll weld the tube into the door jamb and then seal around the other end in the speaker box. Since the tube runs downhill, there should be no way for moisture to enter the enclosure. Now I just have to repeat the process on the driver side door.
