I purchased my Cozy plans almost one year ago, and I am just now gearing up to start my build. I live in a 3 story townhouse with a garage door in the unfinished basement (aircraft factory) with just enough room to build. I have spent the past year studying, reading and buying tools and equipment. I intend to purchase as many chapters as I can afford with my tax refund this year to get started. I am in the process of procuring materials to build my table. My place of employment uses a 3/4" MDF that is faced on one side (to be the non work surface) with a gray, textured non-slip PVC surface, and the other side is smooth, white melamine. The company regularly discards pieces as large as 4 foot square, and they are very generous when it comes to scrap materials. I intended to use 3 pieces 4' x 4' for each side of my work table. I was uncertain how the melamine and epoxy would interact, so I searched "melamine" here and this was the only thread that came up. I was glad to see that melamine was recommended, but dismayed and left curious by the recommendation against white. So, my question is quite simple. Why not white? If I can get it for free vs. who knows how much from elsewhere, why not use the free stuff? Most of the other fixtures in my shop (a rolling toolcart/workstation, fiberglass and epoxy storage solutions, industrial strength outlet strips, etc) were also free and I would like to continue this trend, but not if it will cause significant troubles or inconveniences down the road. I was planning to pick up the MDF later this week, so some input here would be greatly appreciated. The Toothless Hillbilly
