Doing a glue up of 74" long pieces for a 30" wide table top. Using domino tenon's to help line up height of top across the joints. All the lumber was milled the same thickness on the final pass through the planer. Made sure to final joint the mating edges alternately on the jointer to allow for any variation in 90 degrees. Made sure to square the domino and keep pressure against the top as I made the mortises. Mortises were 2-1/2" from either end, one in the middle and 12-13" between those on either side. 7 mortises in total across each face.
Did a test on some scrap pieces and got a smooth joint. I made sure not to turn a board over inadvertatly. I still get height variation across the joints? I am sure I can clean it up, but....
Not sure what I might be doing incorrectly.
Thanks for any input.
Thanks.
