I am building a fairly large table and asked about dealing with the wood movement a few days ago.
After much thought I have decided to securely fasten down the middle of the aprons perpendicular to the grain and fasten the ends of those aprons down with clips.
The aprons parallel the grain have to be able to move .8". I will glue fiberglass dowels into them, and have the dowels ride in blocks attached to the table. Does this seem reasonable?
Questions:
1) As the wood expands, will the holes in the blocks get smaller or bigger? I am guessing the hole will get larger, but I am not certain about that. 2) What woods have minimal movement. Would nice oily teak be good? I have some scraps of that laying around. (I have some lignum vitae also, but that seems like overkill.)
