I am planning to put together a desk top that will be 60" long by 26" wide, thickness 1.25", I am using an average of 5" wide planks of Tiger Oak and surrounding it with 4" wide English Oak with breadboard ends, I had condidered mitre joints at the corners but did not think they would be strong enough. I am thinking along the lines of using slots around all of the tiger oak and using loose strips of wood, no glue, the only place I was going to glue is at the four corners were I was going to use T&G joints, My client keeps his house VERY warm and I have had trouble with movement at the joints in the past, he does not want any of the same problems with this desk, will the method of fixing I have outlined allow enough movement between each piece so any opening will be un- noticable, I am using a hard wax finish with plenty of wax, both sides will be finished the same. The desk top will be well supported.
Any alternatives would be welcome or am I on the right lines?
Just had a thought! should I apply a small dab of glue in the centres of the long side. Also, is there a better finish for a desk than wax, the client does not want a shiny finish.
