A new chassis for a Bachmann U33B
#3
After the dimensions were scribed onto a piece of .015" piece of brass sheet and cut out I began forming the bends. I started with the sides, clamping them between two 1/4" square bars in a vise and bending them over and flattening them out with a small hammer.

   

This shows the first two bends completed.

   

A 3/4" wide block was used for the next two bends.

   

   

The assembly was then clamped in the vise long ways as shown. The tops of the sides should be flush with the top of the vise. This will make the floor pannels higher than the sides so they will be up inside the frame rails. Then bend the ends down.
