My opinion is that its not made from seperate pieces of wood but the moulding is not one cutter either, looking at it then it would not be that hard to make a new piece using two cutters. A rebate type cutter for the inside step then a quarter round cutter for the outside radius. N

Hello and thank you all for the welcome and the responses.
It's definitely not two pieces of wood.
I will be replacing a large section and adding another 25 feet or so of railing.
I think I will first try the table saw first for the ledge and then use the router for the bead.
Will report back with how it goes.

Do the step with A router cutter, it will give far better finish than a saw blade will. N

Looks like a job for a shaper?

Maybe originally it was run on a spindle, big cutter, to make just short pieces, that needs imagination, two cutters will do it so close you wont see the difference. N
