I spent most of the day working on the forge. I had some good progress, some setbacks, but I did manage to get accomplished what I wanted for the day.
As a recap, I was rebuilding the escapement support that I had made a while back. The primary reason that I was remaking it was that I wanted to make sure that I had enough clearance for the verge and foliot. The other reason for remaking it was so that it would more closely resemble a surviving escapement support from the same maker of the clock that originally inspired me.
So the original that I made looked like this...
I started yesterday by making the post. The first step is to mark where the shoulders of the tenon will be. This is the tenon that goes into the clock frame. For a sense of scale, that bar is 1" x 1"
I then taper the tenon down.
Next. to put shoulders on the tenon (to make it easier to square up to the frame...), I use a bolster plate. The metal is heated and hammered into the hole to set the shoulders. This also upsets the metal a bit to make the flare that will go against the clock frame.
After the tenon is done, I switch to making the piece that goes up. This is just a post of about 1/2" width. Just a matter of drawing it out.
Now, I need to do the flare for the base. I do this by putting the piece in the bolster plate and using a square punch to push some of the metal down and out.
With a bit of metal to working with, some work with a ball pien to help define the base a bit more. This was picture was taken before additional cleanup.
I now turn to making the top piece. This is simple techniques of bending, flattening out. The notches in the top were simply made by using a chisel.
This is attached to a crossbar that is in turn connected to the post I created up above.
A picture on the escapement support on the frame. There is still a bit of work to do but night time was setting in. It is very close to being done.
This picture is just to show the size difference with the old one.
It is much higher than the old one. I still need to clean it up a bit. It needs a little more hammer work to straighten it up and some file work to clean it up.
Overall, I am happier with this one than the first one. There are still some minor things I would like to redo. However, in the interest of making progress, I am going to hold off making another. When (if) I complete the clock, I can always remake it. But it should be usable until then.

BTW, it's "when", not "if".
