Did I train you? I've done several things like that on different projects.

Nice work, looks great!

Replaced sparks plugs yesterday. Already did the wires after one fell apart. As I changed them, three disintegrated in my hands. Pretty sure they were the original wires. The plugs didn't look to be much newer:



I mean, GM platinum plugs look to have thinner electrodes, but these were almost wore down to the size of a needle:



All buttoned up and cleaned a little:



Or... so I thought. Took her for a spin, and there was definitely more power, but a hesitation and misfire now. Uh oh. Immediately remembered when tightening the furthest back plug on the driver's side, I heard a crack. Thought maybe the porcelain had cracked? At least it was worth checking out. Perhaps the crack was causing a jump from the plug over to the block? Yeah, was a bit more than that:



Replaced that plug, and geez Louise does this car haul the mail now. It's ridiculous what just plugs and wires did.

[Notloudenuf]

See if they will warranty that plug

Started on some tweeter mounts. Look like crap so far, but just playing around with some ideas. Cut about an inch off of some PVC caps, and JB Welded the rear mount securement brackets for some Image Dynamics XS28 tweeters on there. They're definitely solid after the JB Weld cured. Should allow for some decent aiming once secured to the brackets I'm pondering on making for the doors:





Also drawing up some plans for a multi-piece baffle that will semi-seal the trunk area from the cabin. Effectively reducing some of the road noise these Z06 cars are known for, but also giving a 13" tall by 28" wide angled baffle for mounting two IB subwoofers. And also offering up room on each side for 1/2 cube enclosures to use for midbasses. Updates on this course of action should be arriving soon.

Started putting together a rough template of this multi-piece baffle idea. First step, cut to 17 inches:



Steps two through thirty-four were a bit more complicated:



And now after all that, have to calculate a 200 and 7/8" radius for the top. How in the... well. Easiest way I could come up with to do it, measure out 200 and 7/8 inches:



Got that top arc:



Transferred that final top measurement over to some super thin plywood to mess around with:



Annnddddddd... Chit. It don't fit:



Using the bottom part of this baffle though:



Determines we need to make some adjustments to the extended portion:



Will work on that more tomorrow. Getting dark out for tonight. But so far, I think this will work out.

Chit why not just make a cardboard template? Get some scissors and a pencil and go to town.
