I don't have a router table, and I am skeptical of my ability to line up tongues and grooves well enough. I wondered if I could make the rails and stiles both with grooves, using small "splines" (if that's the right word) to join them together. I looked online and found a video that suggests just that.
I've got lots of puzzlements. The first is, how deep should I make the grooves? Is 3/8" deep enough? If so, it would be pretty easy to cut "splines" from the same Oak 1x3, since they'd need to be 3/4" wide.
Here's my "off the top of my head" plan.
Do the math, based on the groove depth I choose. Cut the Oak rails and stiles to length. Rout the grooves. (could it be better to rout the full lengths of the stock, then cut to length?) Make the splines. Cut the panels. Should I make them a hair small, I wonder? Or is there something to be gained by having them fit right to the bottom of the groove? Prepare the various surfaces, BEFORE assembly. I assume that any kind of sanding/scraping/planing will be pretty difficult once I glue up the doors. Ease the edges and corners. Glue up the doors, (including gluing in the panel edges I think), clamping the rails and stiles flat on a flat surface in addition to across the width of the door. Struggle with finishing, as usual.
Thanks in advance.
