I have made 3 table tops by doing conventional edge gluing: alternate grain, use biscuits to hold alignment, use TiteBond 3, use of cauls and 25 lb weights to maintain proper pressure to minimize cupping.
What I additionally do is to plane the top once edge glued using my cnc router. I measure the inevitable slight misalignments or cupping of the boards and remove just enough from each side to get a perfectly flat table top. This usually only requires taking about .125 off each side.
Now here is my question…will this cnc planing help to maintain the perfect flatness or might the boards still warp over time?
I plan on making a Dutch Door for the house entry. I will be using very thick pieces of ash (probably12/4) and cnc plane it down to size after edge glued.
Are there any special facts, suggestions, instructions, that I need to keep in mind while doing this project? I’m concerned about warping due to it being an exterior door.
All comments are welcome.
