I discovered yesterday that the last 2 rounds of "final resin fill coat!" were NOT fully curing.
And so, I had to recoat half the machine- again.
Lovely 100% humidity, old resin and probably not enough wax.
Tried heaters? They drive off moisture as well.
I'm the household member who gets to inter any critters the cats have had their way with.
Funny, the very sweet, runty, orange female was the one who decimated the rodent population!
Ah, a ginga ninja! Very dangerous indeed
I think the issue was that the resin shot off so fast (damn humidity!
) that the wax didn't get enough time to float up.
Hence, gooey surface.
And it took me until my third redhead girlfriend to understand that I was out of my league there
But to the theme...
not sure WHY anyone else would ever have the need to sweat mounting speakers to a convex surface in any reasonable build, but I archive the mess here anyway.
For added fun, the panel the speakers are going on also happens to be only about 3/16" thick (so I could actually bend it the way I wanted it to go.)
I thought a while about what material to use and instead of shaping some foam and gluing that in, I thought why not just make a plywood ring.
6" hole saw for outer cut, 4 1/2" saw for inner.
Make a half depth cut with the 6" to have a pilot hole to maintain concentric ring and scoring of outer cut also.
Switch to 4 1/2" and make full cut to knock out center, switch back to 6", finish outer cut and remove ring!
I also ran the router around both sides of the inside ring, to make extra space for the speaker cone (just in case) on one side and on the other side to accommodate the screen.
I just used some KwikMesh that I had left over from doing the bird block on the eaves of the workshop and the house.
I also had to shape in some concave to the rings so they would sit squarely on the inside of the panel and actually hold the screen down while the glue was setting.
Tip the machine onto its nose, add a few lead shot bag dive weights to hold the rings and screen in place and voila!
Both sides are getting a gloss coat again to get a flatter surface after another sanding.
Finally getting really close to being able to put some electronics in this thing.
Till next time... don't forget your mask!
