I’ve got the base completed and am now ready to construct the top. The island is 92” x 42” and I’m looking to build a 3 inch thick end-grain top. I’ve got planers, jointers and ample woodworking experience, but this presents a few special problems that I’m looking for advice on. The cost of the hardwood is such that I can’t “learn as I go” on this one.
My plan is to use a substrate like plywood, stacking three 3/4” sheets together to get a 2.25” base, and then glue the 3/4” walnut end-grain to it, and then glue the full 3” thick walnut end pieces around the edges.
I’ve found very little on the web in the way of advice for something like this, and as a long-time reader I felt it was time to come out of the shadows, create an account and throw my project at the mercy of the lumberjocks.
Some concerns are the seasonal expansion issues and bowing of a top this large. I’ve also found some people suggesting to insert long metal rods to keep things square and true.
As this will be in my kitchen I am more forgiving to a project that comes out less than professional if it takes a turn for the worse, but obviously I’d like to get it right the first time. I’ve seen tops this large built before, and Grothouse Lumber just did that monster nine foot long end grain teak island for This Old House, with a 3 1/4 inch thick top and a super double roman ogee profile.
Any advice you can give me will be much appreciated.
