I'm working on the design of a round dining table top using ambrosia maple cross cut disk from a tree about 24" in dia. The table is 41" in diameter. I cut the wafers 3" thick about 2 years ago and they are reasonably dry now. The table top will look pretty much like a jigsaw puzzle of 26 irregular shaped pieces ranging in size from 20" to 4". I have the layout drawn for cutting the pieces with my CNC router. Now I need to offset the cut lines inward a small amount to allow for the glue joint and any other clearance needed to get a fit that is not too tight or loose.
Any idea on what kind of gap I should leave between each piece, I'm thinking around .05 I've not decided on the glue type but it's going to be too big to glue in one attempt.
In case you are wondering, I'll use the CNC to true up the outside edge and flatten the top after the glue up. Also, just for information, none of the disk split while drying and only have radial hairline cracks that will fill easily, probably with epoxy, maybe colored.
The base will be welded steel and I am considering putting a steel ring around the outside edge of the top. The chairs will be steel and maple.
Thanks,
Perry
