well, tops are done. I had to grind/polish last weekend, when temps were sitting at 32-34 and windy...so that kind of sucked. In the end, I looked like a big, frozen trash bag, since I made my own makeshift poncho out of leftover black poly - and the mist from the waterfeed coated everything in a thin layer of ice. The whole time I was miserable; cold, wet...thinking to myself this isn't going to work. Well, the wife and I couldn't be happier how our first tops came out!. I still need to put a final urethane sealer/polish coat, but other than that these things are complete. To reiterate what others have said before me, you'll be very surprised at how much mess you can make, how heavy these things truly are - and how much you will appreciate all of that in the end when you have a hand/self-made, beautiful countertop in your home.
Thanks again to all those that have contributed to this thread before me.
Sorry, crappy camera phone photo. I'll try and get some better quality shots up soon.
