I don't know why you'd want my feeble attempts at instructions when those websites have whole pages of far better stuff than I can put in a few sentences, plus illustrations. but here goes...

Put masking tape down the center of your limbs. (Unless you just like sanding pencil marks off of your bow's back.) Measure your limbs to find the exact center and draw a line right down center of the bow, from one end to the other. Measure 1/2" wide for your limb tips. Draw a line from each side of the tips to the base of the limbs at each end of your handle.

Cut away everything that doesn't look like a bow. Sand the edges smooth. Sand a 1/16-3/32" radius on all the corners.

Then the hard part. Roughing the limbs' thickness and doing the tiller. Your choice whether to do a flatbow or deep stack "D" belly. I like flatbows myself.

First mark 1/2" thick at the tips and draw a taper line from the tips to the limb fadeouts. Cut off excess wood. File in some string nocks into your limb tips so you can string the bow for tillering. You do have a long tillering string, I expect. Now you're ready to work on tiller. Remove wood from the belly until each limb bends smoothly and evenly, and both limbs bend the same amount. Work each limb down carefully with a wood rasp, and then with scrapers when you start getting close, until you hit the draw weight you want.

Shape your nocks and limb tips the way you want them and be sure to polish the string nocks really smooth. Rough string nocks will flat eat up strings in short order.

Sand out all rasp/file marks with finer and finer grit sizes. Finish off with 500 grit. I like to take a piece of smooth steel rod and burnish the wood, but it's not necessary. Apply finish of your choice.
