I need to recreate some forty blades for decorative architectural fans found on the corners of the gables of an old house. The shape is very simple, and I have several complete blades to use as templates. What I didn’t realize is that the thickness of the blades decreases from 1/2 inch at the widest portion (3 inches at the half circle) to about 1/4 inch at the end of the taper. I have a thickness planer and had planned on have to plane 3/4 inch stock to 1/2 inch, but I don’t know how to accomplish the taper in the thickness, short of hand-planing, which is simply not going work time-wise. Any ideas? Thanks.

Run them through the planer on a sled with a 1/4" shim under one edge & create a small fence on either side of the blades to keep them in place
No one should regard themselve as "God's gift to man." But rather a mere man whos gifts are from God.
You can make a sled for your thicknesser. The idea is to raise the front end of the piece into the blades 1/4" higher than the trailing end. Just make a box out of 3/4" ply (so it's stiff enough to support the piece without sagging under the planer's pressure rollers) that slopes like that, put cleats on the ends to keep the piece in place, and run them through until it cuts the whole length.
You can also taper on a jointer if you have one.

sounds liuke they just used some beveled clapboard siding to make them.
or are they tapered in the long direction??
a sketch would help.
to taper them olng wise ( or width wise)
make a sled you and run thru your planer that will hold the board with on end raised up the difference in the thickness of he final blade.

They are tapered lengthwise. The sled idea sounds good. I'll have to play with that, as I'm not quite sure how to do it. Thanks for the advice.
