I am working on a simplified version of Northern Tools brake press:

With the lower die at 90 degrees (I am using a piece of scrap angle,
3x3x0.5 wall), I presume the upper die should be less than 90 deg.
Correct? I am thinking of about 80 degree angle. Your thoughts?

My brake press will have a 11.25 length working surface (mainly
because the piece of 1x4 CRS scrap that I have is 11.25 long) and at
this time I am going to try to make it work without the two guide
posts.
