After building the frame for the starting step, and having ground down the birch plywood to between 1/4 to 3/8" I took it to the radial arm saw and cut a series of kerfs in it so I could bend it around the smaller radius on each end. Lowering the table on the radial arm saw allows me to make the kerfs. Fine line to walk here, cut the kerfs to deep, it will crack and kink, this is going to be painted, so any kinks will really show up after it's painted, don't cut them deep enough, it won't bend properly and still crack, lots of kerfing, bending, rekerfing until you find that happy medium. Had to use 2 pieces of plywood for this, with a joint in the middle, some Bondo to fill in the joint, sand it, more Bondo and it was good. Overkill bondoing the joint, since there will be a carpet runner down the middle of the stairs, should the home owner decide not to go with a runner, we've got our butt covered.didn't think to take pics when this was all clamped up, but here is the end resultafter the starting step riser was done, I laid it on the tread blank I had already glued up, traced the face of the riser, and using a scribes, scribed the tread an inch and a half larger, to accommodate the overhang of the tread over the riserkind of like this.I shaped the nosing, and each end of the tread in the shop, all other cuts were done on the job site, again I didn't think to take pictures of the tread blank and its progress in the shop, sorry. Probably another 6 hours bending this starting step, sanding down the tread blank, ridiousing the nosing, using a 1/2" radius bit in a hand held router, and sanding the flat spot on the tread that the router bit can't catch, the tread is about 1 1/8" thick

Keep the pics coming Kenny...really enjoying all the detail...

Fancy little scribing tool you have there

nice nosing on the stairs!!!
