Looking for ideas on simplifying the process of making L-shaped flat mouldings (a "flat crown") that are applied to cabinets as a top-mount option.
The face portion is about 3" tall, the cleat is likewise about 3" wide, all made from whatever 3/4" material matches the doors. Just for context, these are contemporary flat-slab kitchens that do not go all the way to the cieling, so we attach these top of the cabinet by screwing them from the top down (no visible nail/pin holes).
We're going to need to be assembling 100-300lf per day of this material, and we need a process that will work for prefinished materials such as melamine and high gloss acrylic overlays as well as with painted plywoods/MDF.
We prefer to make these in 8-12ft sticks depending on what the chosen material will allow.
We've considered grooves and lamello biscuits, and just assemble with squeeze clamps. Pocket screws will work but nobody wants to hit a pocket screw on the miter saw out in the field. I don't think anyone makes a fiberglass screw that's strong enough for this.
Should we look into investing in machinery that makes slide-connectors work here?
