need a little woodworking advice

i need to make little bracket feet for this casket using 1.75" wide, 7/8" thick rock hard century old white oak. i don't want to use the brad gun, so my choices are mutilating some biscuits and trying to cut little slots on little pieces of wood, making a jig and either cutting splines on the table saw or router table, using corner clamps and gorilla glue and a butt joint. i wonder if making a 8" square, gorilla glue and a spanish windlass is the way to go. i can cut the separate feet out after everything is dry. trying to clamp feet that are only 2" long might be tricky.

instead of biscuits have you thought of 1/4" dowels no slots to cut or biscuit mutilations...also why gorilla glue instead of plain ole woodworking glue?

never used gorilla glue before so i wanted to try it out. guy at ace said he fixed a broken board with it and then tried to break it again and it didn't break at the glue line. dowels might work..i really only need something as a locator, so the joints won't slip during glue-up. i could make some kind of fixture for the drill press so i can put the holes in the exact same place on all 8 pieces.
i'm also worried about the mass quantities of end grain on the top. i'm going to use linseed oil and shellac. hope the end grain doesn't get too dark. maybe have to use some sanding sealer. you should have seen the blade exposure on the table saw when i cut the bevels. scary.

If you're going to use Gorilla Glue, then practice with scrap wood first. I did not take into account the degree of expansion that it does when exposed to moisture the first time I used it and it lead to some quick adjustments I hadn't planned on.

I agree on the doweling and the wood glue. With expansion of gorilla glue the glue lines can become horrendous and let me tell you that standard wood glue can be amazingly strong when applied properly.
