I'm thinking about what to use for my endcaps on my sonosub I'm planning. I want a nice oak look but don't want to veneer the edges of MDF. Can I use 1 solid peice? Do they come that big? I'll need it to be about 18 1/2" dia. and 1/2"-3/4" thick. What are my options for a nice finish on top and on the edges? I will also roundover the edges from both sides to get a complete roundover. Thanks!
