[TheForge] sheet metal brake

[Bob Ehrenberger]

I just uploaded pictures of my brake dies to a folder labeled Sheetmetal 
brake.

Because my press has such a large ram I needed a blade that was at least 4 
1/2" long to give me clearance.  The closest thing I had was a section of 
grader blade which was 1/2" x 5 1/4". The hardest part of the project was 
flattening out the camber in the grader blade. It took a lot of heat to get 
something that big hot enough.  I also forged the edge of the blade to 
center it on the bar.  Not knowing what the blade is made of I anneled it in 
vermiculite before welding.

So far I have just bent a couple of test pieces, it did them with ease.  I 
may have to add a spacer to the V block if I want to do a bend close to the 
edge of a sheet, I guess I'll see.  By spacer, I mean another piece of angle 
iron with shorter sides which would put the center line closer to the edge.

I've thought about doing this for a couple years, so most of the design has 
been worked out in my head just waiting to be implimented.
