I am building a wooden raster, 7 feet long and 1 foot wide, for our in-the-ground heater in our living room. The design has two pieces along sides which support 64 cross pieces evenly spaced along the length. (see the attached image -this does not show the half-laps, but shows the general design)
I want to use glued half laps to attach the cross pieces resting on the side pieces using half-laps. So that is 128 x 2 half laps, each about a half inch in width and depth.
How can I most quickly make these using a basic tablesaw (I do have a sled), and/or a home made router table (it only has a fence, no tracks), and/or a bandsaw (blades cut a bit rough)?
Mainly I am challenged by: how to repetitively make precise laps along the long pieces
But I am interested in best practices for any aspect of cutting both parts in large quantities.
(I do understand how to a) set my tools to the correct height for these, and b) how to use a stop block to repeatedly cut in the same place using the table sled (but that does not work with a 7 foot length of wood with many slots to make…)
