Standard Z Angles 6-B-1 Z. I cut some blanks 1219 X 90 and bent a 90 deg bend
on the brake in the normal way. Then I put the 100 X 35 spacer with the slot in it
in the brake and bent the other flange as far as I could. I then hammered it over
the rest of the way with a rubber mallet, using a pre-bent 60deg strip to check
as I went along.
Very happy with the result. Two completed, four to go.
3.5 Hours.
