...for a week and a half's work!
My current shop work is on the Richards House railings, which are covered in more detail in an earlier post.
These are the sculpted bars that will make up the support elements for the two matching diagonal stair hand rails, each finished to about six feet long. The starting stock is seen in the centre, a length of 1 1/2 x 3/8 inch flat, for most about four and half feet long. The ends of these have been flattened out under the air hammer using a Hoffi style crown die. The finished shape is canted to one side, roughly to 2 1/2 x 1/4 inches. Each of the bars has a long tapered section, reducing the width to roughly 1 inch and increasing thickness to about 1/2 inch.
The next step in the process is forging each bar into the curves seen on the layout drawing underneath. The bottom ends of the arches also needs to have a 2 1/2 inch offset step added. This so the finished hand rail will clear a protruding cap stone beside the mounting points.
