M and D's Victoria's Farmhouse

That is surely a clever idea. Do you mind if folks borrow it?

Anyone can make this. Cut some scrap plywood at the correct angle of the stair rise and run, then fasten it to another scrap that will lay flat on your work table. You can even clamp it down if necessary. I use a heavy elastic band to hold the treads and then start the pickets. One you have a top and bottom post or picket installed correctly the rest go fairly easy. I use a clear plastic drafting square to check that every picket is vertical.
