I am going to edge a piece of 3/4” plywood with a 1×4. I am trying to figure out if it would be stronger to have the tongue on the plywood or the groove. or doesn’t it make much difference??? I can cut the 1×4 on the router table, but not sure if I can handle a good sized chunk of plywood (finished panels to be 39×78) on the table. I think I might be better off cutting hand held (I have a over sized base to keep the router from tilting—but it only fits my smaller router so I might be better off with the grove in the plywood)

any thoughts??

I’d put the groove in the plywood so as to not have problems chipping the veneer.

I usually put the tongue on the banding by putting the tongue on first and then cutting to width.

I would just put a work support to either side of the router table and cut the groove in the plywood there. 78” isn’t small but with simple supports to help out you shojldn’t have any problems on the router table.

I go with Jim. Put the tongue on the 1 X 4. You can use a guide clamped on the plywood to guide the router as you cut the grove in the edge. I would use a slot cutting router bit with a bearing and have the bearing ride on the clamped on guide.
Another alternative is to use biscuits for alignment and support.
