Here's some good news and some bad news. But first let me say that I can't recall the last time I've ever dropped anything, as in anything at all.
I wish there was some way to blame this on Bwaslo, but after thinking about it all night, I can't seem to pin this on him. And that's a real shame!
I finished gluing up the CNC'ed 2 cu ft test boxes and went to Bwaslo's house to help wire everything up......another 104 degree day......so we worked inside. Woofer sits in nice, waveguide sits in nice, binding posts, crossover, and then Mr. Bwaslo brings out the insulation made of denim (there's a reason I mention that).
I rip the insulation into pieces with my hands and stuff it in the boxes.
After both boxes were complete, we decided to listen to his other DIY horns first because they were already wired up. They sounded great! Next up, my freshly cut 65lb mdf boxes with nice sanded sharp edges along the bottom. I picked one up, moved a little.....yep....it slipped. Tried to grab it, and pushed my leg forward to try and slow it down as it fell. The top of the box went forward and the sharp back edge slid down my shin and peeled the skin back like a banana peel! And of course the back top corner hit the floor. That's and end over end fall!
It was by luck that his wife had her earphones on upstairs and didn't hear anything!
So anyway, the good news is that the waveguide proved strong enough with only 4 screws and a 5lb compression driver mounted on the back to handle a significant fall at a funky angle that would have put a lot of pressure on just a couple of the screws. The bad news is that the skin on my leg can not!
And the box now has a dent that I must fix. But no damage to the components. I suppose this was a good test for the waveguide and I donated some of my skin to prove it.
Luckily (I guess), I'm a landscaper and my shins get beat to heck all the time and constantly have wounds. So it just doesn't bother me that much. This one looked worse than it actually was. Normally I just grab onto the flapping skin and rip it off while it still burns a bit. But my leg was at an angle and the edge of the box must have cut in deeper as it fell. Basically I couldn't rip off all the skin and took scissors to it last night when I got home.
Before I left Bwaslo's home, we were picking up all the tools and stuff. I kept noticing that my hands had a strange slippery feel to them. Like after you use silicone caulking. Mr. Bwaslo wondered if it was due to me working the denim insulation with my hands. The drop really bothered me because I really don't drop anything. So today I decided to open one of the speakers up and get out the insulation. Sure enough, my hands now feel the same slippery way. It must be the glue type material that holds the denim insulation together. I really don't know. Add that to a just sanded mdf box and there's a recipe for a fall.Edited by Erich H - 7/8/12 at 10:27am
